To people asking why, this is a good lesson on the Collison’s ambitions. Stripe is one of the best API companies in the world. They know how to serve high volumes of latency and availability sensitive requests. They’ve abstracted the financial rails for payments and now want to abstract the rails for LLMs.
They’re the perfect company to own OpenRouter.
Tokens are simply a lightweight valuable asset. Stripe can serve as the middleman as well as anyone. They know how to route to many providers (payment rails) with huge differences in service characteristics. LLM providers are far easier.
Then they can work this into an offering where users can subscribe to tokens and use them across services. It solves one of the core monetization challenges of every AI company: how do you price when your costs are variable on usage, but nobody can make sense of charging by token?
From here, they can start hosting their own models and competing as an AWS for tokens. They can be the best provider of $OPEN_MODEL, or their own, and optimize for you.
You'd be surprised how little volume of api calls payments companies get compared to advertising companies or consumer internet companies. Stripe aren't especially well placed to own this asset on a technical level. That doesn't make this a bad acquisition per se, but there is no magic stripe can inject here as far as infra/technology is concerned.
You'd be surprised how antiquainted many of them are. I don't mean Stripe or Braintree but the long tail of terrible terrible credit card processors. If I hear "Chase Payment Gateway" I shudder.
Stripe's APIs are very good. They could be better, but it's difficult to change the underpinnings of financial infrastructure. A lot of risk, little incentive to move, and you're designing something that has to last (and make sense) for 15+ years in the future.
I worked on this at Stripe in 2022. We were the first teams to start building v2 APIs and data models to solve exactly this problem. The first target launch date (in Feb 2022) was November 2022. It was launched in May of 2025.
My reporting line, as an EM, was Netflix, Oracle, Oracle. No one had startup experience. It was drenched in politics. The engineers were largely brilliant, kind, and hardworking.
I still love the company and believe in Patrick. Believe me, he deeply understands what you're saying and wants it to be the best it can be. But it was clear to me, even then, that they'd lost a lot of what made them special. They could maintain it, but I wasn't sure they could do it again. Banking-as-a-Service was one opportunity, Link was another, and now this will be a third. We'll see. (I say this with a lot of love for Stripe and Stripes.)
Coincidentally, I had a conversation with a recruiter at Anthropic and saw them doing something very similar. They were starting a new team in a new vertical and wanted someone with experience running an org of 100+ people. I would bet real money that it will be a fraction of the product/impact it could be (though still probably make money!)
I mean. They used to be good. When they started out their docs were absolutely far above the competition. They aren’t now, and Stripe has lived long enough that they’ve seen themselves become the villain.
Feature bloat definitely made their API and product docs harder than the early days. Stripe Checkout would have saved my teams days, but I agree, they need to go back to their roots and make the 99% use case very easy.
(Not picking on you here, you just provided a well-written peg for a popular narrative. I'm aiming to sharpen my own thinking here & perhaps learn something.)
This seems like a stretch given the rise of local inference, especially the Prism Labs rumors from a few weeks ago.
One way I think about LLMs is they are akin to fancy databases in that they are software of which you can ask questions and get answers if you ask properly. Oracle & SQL Server are akin to OpenAI and Anthropic, and there are analogues for MySQL, PostgreSQL, SQLite, MongoDB, PlanetScale, etc. (This is an analogy, it's not going to be a perfect fit.)
In that view, would it make sense for someone to say that their credit card processor just bought the company that makes their ODBC driver? Would anybody suggest that the TPS of their RDS instance is a lightweight asset?
I don't see this as strategic beyond the obvious idea that Stripe wants to get closer to AI, and they haven't been able to get the market to care about their natural linkage to AI (Radar).
> they can start hosting their own models and competing as an AWS for tokens
The financial pressure of doing this has caused cuts to core product teams at the richest companies (which Stripe isn't!). I would not want my payments processor to go down this road and to get worse at processing payments.
Your simplification itself is compressing away the meaningful point, and then you're confused about your own over-simplification.
Stripe is not a "credit card processor", and that's not the point of OP's comment. The point is that being the intermediary between merchants and processors is the valuable expertise in terms of an OpenRouter acquisition.
It's been a few years, but I used to work on almost exactly this (not at Stripe, but we processed hundreds of billions annually). If you're a big enough merchant (or Stripe itself), you can choose to send a credit card transaction to any one of potentially many processors, each of which have their own performance characteristics (one may approve at a higher rate, the other may charge better fees, etc). All of this subject to attributes of the transaction itself (ticket size, geography, card type, many others). You know quite a bit about the transaction itself before you send it out, so you can build up routing knowledge to optimize for whatever thing you care about (usually transaction success rates or fees).
See how this starts to look a lot like OpenRouter with money instead of tokens? I'm not sure I 100% believe that's how it'll shake out, but there is a transferable skillset.
> would it make sense for someone to say that their credit card processor just bought the company that makes their ODBC driver? Would anybody suggest that the TPS of their RDS instance is a lightweight asset?
Would is make sense to say that their online bookstore now sells Ethernet cables, bidets, and delivers groceries? Sells _cloud infrastructure_??
Amazon made two transitions:
1. Amazon the online bookseller => Amazon "The Everything Store"
2. Amazon the online retailer => Amazon the Cloud Services company
I believe what Stripe is doing here is closer to (1). "We are good at high-throughput APIs that wrap complexity with thin margins. We did it for credit cards, then ~all payment methods, now other digital bits."
In this context, tokens are much, much easier than international payments.
Now: Is it outlandish for their customers?
Not really. Every engineer knows stripe as an engineering company. I don't think Stripe is what it once was, but it's certainly a generational company. You're asking engineers—who broadly have a positive impression of Stripe—to use this product they already know. OpenRouter gets the positive brand association (trust) of Stripe; Stripe expands into a new domain whose technical needs are extremely similar.
Ok, at first I didn’t get it and thought it would make sense if stripe just wants to build payments for agents, but on a second thought your idea about “once buy tokens — use everywhere” is very good one!
Here are some things that are abundantly clear to me.
1.) LLMs are useful for programming
2.) Open models are excellent and will continue to improve
3.) Economies of scale and ease of access mean self hosting is out of the question for a large number of users
This means that even if the largest labs are not worth trillions and a large amount of the data center build out is not as valuable as the builders project and GPU/RAM prices plummet, it will not matter at all for this business. People will want to buy cheap open source tokens from a centralized trusted provider.
$7 billion for a business with little overhead that is already within their core competency and has strategic growth potential seems like a very good deal.
What does openrouter actually do though? They buy a bunch of tokens from token providers and allow you to easily route queries between token processors?
This seems like the kind of thing that you can have Claude write in an afternoon for whatever service you're running. I don't see the value.
Unfortunately we don't really know anything about OpenRouter or Stripe's numbers. They're both private companies. AFAIK there really isn't much information publicly available about how profitable or not OpenRouter actually is, or whether it has a little or a lot of overhead. So I can't really say whether $7B is reasonable or inflated. It seems like an enormous number, and my hunch is like all the other enormous numbers floating around in the AI space it's probably inflated by the hype bubble. But we just don't know.
Broadly I agree with you. It seems like they have an in-demand product and there could be a sustainable business there at least in principle. But whether it's a $7B business or a $70M business I can't say.
depends what the tulips are. tokens? private growth stage shares?
openrouter is involved with a lot of scammy crypto personalities. maybe they are the tulips people have been manic about for too long. maybe the collisons are the tulips.
You're asking how someone missed llms. On this website? That demonized them for years and is only now fighting the cultural battle to accept them as useful?
I wonder if this deal is primarily just to buy payment volume.
OpenAI just announced earlier this week that Ayden would become their payment provider (when it was previously Stripe).
And OpenRouter has a large percentage of overall AI payment volume for all the major labs.
Both OpenAI and OpenRouter represent ~$100B in payment volume, whereas Stripe in total doing ~$2T. Two customer doing ~5% of your total volume who didn’t even exist a few years ago, must be kind of scary for Stripe.
OpenAI is a large company, and large companies go multi processor for payments. I would check the press release carefully, and see if you can confirm that Adyen is taking all of OpenAI's volume, of even a majority of it.
Adyen just bought Orb [0], a usage-based billing company, for $335M, specifically so they could position themselves as the payments choice for AI companies.
Stripe would lock in volume but how exactly are they monetizing that? Any margin the get from OpenRouter is money extracted from OpenRouter’s revenue (which is now theirs.)
7 billion one off for 100 billion annually? If I am understanding that correctly it feels like a no brainer to me…
Also if you think about it differently… OpenRouter is adjacent to what Stripe is but for getting access to AI models. If they dont mess this up they could invest in openerouter and grow that 100b pie.
How can a middle man for api calls be worth so much? Their market share can’t be very large right? For comparison, $7B is more than market cap of Lyft, Dolby, and Alaska Airlines. What is happening?
It's an inflated number due to the AI market, but their selling point is distribution.
Many people and businesses want to experiment with different models, but they don't want to sign up for a dozen different services. Businesses can make it difficult to approve new vendors. If your company is looking at 5 different vendors for tokens and teams can't agree to switch together, OpenRouter comes along with a unified interface and a single billing point.
They also become the point to add value-add services on top in a portable way. They already offer some things like automatic JSON repair, but I can see them adding functionality like leak detection tools, monitoring, alerts, and other patterns that a company can set up once and use with all of the models theirs teams need.
What I'm not so sure about is their moat. They have the brand recognition, but it seems rather easy for someone else to build what they've built. I'm a little confused about why Stripe didn't just build the same thing internally. Acquiring this company gives them an instant boost of 10 million customers for their AI business, which might be key to some financial goal they've got.
As a nobody I like OpenRouter because it lets me quickly test out all of the emerging open weight models. I normally use Claude Code but if I run out of usage I'll pull up GLM 5.2 or Deepseek V4 in OpenCode via OpenRouter. Occasionally I'll run Claude's work by a Google/OpenAI model through OpenRouter. If Claude Code becomes too expensive I now know I'll be pretty comfortable with open weight models.

Isn't that ripe for being picked off by aws or azure? Both already have marketplaces where vendors can offer whatever cloud services they want. Both already offer first party inference service, and have contracts with all the stodgy corps where it's "difficult to approve new vendors". Not to mention they have IAM and SSO built in. Good luck bolting that onto a third party vendor like openrouter.
Exactly , not even small startup anywhere in us , eu or nearby will be ok to send data to China, but with open router you can create a no China provider selector with one llm call and start using Chinese llms without paying to vendors a single cent .
What’s the angle for stripe , electrify over tokens exchange is the new money flow , and stripe wants to monetize it. 5% tax on any llm token is an amazing deal
Openrouter is very transparent about where your requests are going. Every single one is logged.
You decide the routing if you want.
I trust it because there are at least 7 billion on the line. If it came out that they were violating their contract and sending company secrets to China when they promised they won’t, they would lose literal billions for basically no gain, and possible criminal charges.
Why on earth would you think they are sending data to China after you click that toggle when they have every reason not to?
For one, openai and anthropic are the top two AI labs and therefore have some reputation at stake. Openrouter is like aliexpress. Any fly-by night vendor can get listed on there.
I prefer using OpenRouter because the money I pay them in premium is far less than the money I lose by not using it on other providers. On OpenRouter, I can switch dollars between models. But for the providers, after evaluating I'm stuck with some number of credits on ones I don't use. This kind of intermediation is actually super useful to me. I must imagine that they can also provide other things that are of value like provider quality measures, ability to swap providers during downtime, etc.
You can't really compare market caps like that. Addressable market or market share is only one piece of the puzzle, and the other companies you mention are in very different kinds of markets, with very different kinds of products, with very different kinds of costs and margins.
A valuation just reflects what someone thinks about the future cash flows of the business.
But yeah, it does feel a bit crazy; unsurprisingly, AI hype affects valuations of AI companies too. On the other hand, I can see the idea that some people might be betting on the idea that the big US labs are bloated and spend too much money, and that the real money is going to be in serving open-weight models, and/or in automatically combining and routing to different models based on the task at hand.
the providers you route to will of course have their own policies, which openrouter surfaces to you through the webui and api. you can even configure automatic routing to select providers based on your policy preferences.
If your data is leaking to OpenRouter, how many companies would be OK with that? So I doubt OpenRouter are peeking inside the workloads that flow through their proxy. However, they do publish "Top Models by Task" ranking[1] so maybe you have a point.
You could just as easily ask yourself how can a middle man for people finding web pages be worth so much, but here we are, and Google is worth something like $4 trillion, mostly on the back of search.
As it turns out, it's very valuable to be the intermediary between a large number of people who want something and a commoditized market of providers. It's the middleman who captures most of the margin.
Now, AI models are not a commodity yet. But things seem like they might be heading that direction. And in a world where they are, Stripe probably wants to be that guy sitting in the middle.
The market cap of any business operating in the physical realm has to account for enormous liability, especially for one like an airline. Also, their operating costs are huge with much less ability to scale, resulting in much lower potential increase in margins.
OpenRouter raised money at a $1.3 billion valuation a few months ago, if the NYTimes reported valuation is accurate.
Going from a $1.3b valuation to a $7b exit in a couple months is an amazing return for those investors. I hope the OpenRouter employees got some decent equity out of this
The reason OpenRouter can build value even if there are 100 clones is switching costs and flexibility. AWS Bedrock may be great for large enterprises, but flexible startups will use OpenRouter for ease, and now they have Stripe's distribution. Once you use OpenRouter, you won't switch because you become embedded in the logs and cost-saving systems.
A large missing link for AWS Bedrock is Gemini model support [0]. And this is a vital feature, because Gemini itself (as far as I'm aware) does not have a real-time daily or weekly hard spend cap in the case of misconfigured or compromised callers [1][2].
Meta's closed source models, too, are only available on OpenRouter (and it's touted as a first-class recommendation on [3]).
So, in many ways, OpenRouter is the only game in town to access some of the highest-funded model families on the market through a single API endpoint.
I'm unsure why AWS is ceding this territory (there have to be ways to allow users to opt into the lesser governance inherent in using third party providers, while not diminishing the brand's governance requirements). But, since they are, it's a meaningful opportunity left open.
Well, you have the logs and specific cost control measures and setups in place. You would lose all that in the event you attempted to switch, plus Stripe owning OpenRouter gives them stronger distribution and further solidifies the switching costs in the broader integrated solution Stripe offers - https://s-1.vercel.app/posts/what-stripe-can-become-broader-...
Historically acquisitions have never really been good for customers. Time for me to look for an OpenRouter alternative? At least they're also as easy to switch from as the model providers they proxy.
No, Stripe's mega plan is to create a consolidated internet offering for internet-first businesses, not price gauging, the masterminds behind this are not corporate suits, rather founders that deeply understand business strategy - https://s-1.vercel.app/posts/what-stripe-can-become-broader-...
Stripes founders aren't suits but they're just as eager to make money. Their payments business is low margin and they're hungry for anything higher margin they can attach.
Yeah, Amazon didn’t let its low margin retail business prevent them from taking high margins in AWS. I’m not sure why it is assumed Stripe would stay low margin.
Margin is not necessarily important. You would much rather be Amazon and take 50% of e-commerce at a small margin than be a SaaS with 80 +, but your market is inherently tinier.
Plus, the ads business built on top of retail is better than AWS and retail. AWS is great, but ads is higher margin, grows with retail, and is something you see across so many aggregators.
Everyone seems to be asking why this a great strategic fit for Stripe.
Stripe can now provide tools to every product that sells metered AI usage and take a cut. This isn't about extracting a small percent on the tokens flowing from your coding agents to your model of choice. It's about all the products that are going to come to market and monetize metered usage.
Want to analyze your 2026 tax return? Use VisorAI's Tax Agent and pay only for what you use. Stripe provides all the accounting, payment processing, ships money to vendors, and takes a bit off the top. Trillions of dollars moving from the labor market to the token market? It's $10B per point in fees for every trillion.
I vividly remember back in 2023/2024, I was sitting on my sofa thinking, "there has to be a market to abstract data access layer, something like Terraform but for LLM provider to avoid vendor lockin". Only if I had access to capital to build something like that at that time, I could have been my try for an AI start up.
Stripe seems to appear to be attempting to compete with the US Federal Reserve as the core dollar payment processor while also dipping into the same for tokens. Core value exchange platform, dollars, tokens, whatever. A bit of a less exciting version of Dune. “The transaction volume must flow.”
Perhaps the US State Dept. used it's strong relationship with Stripe to encourage this purchase as a geopolitical move. They've done so before with companies like eBay and Microsoft to neuter the P2P telephone access network that was "Skype".
Both are in the business of putting a single API key in front of a fragmented ecosystem and charging a convenience fee. This middleman business is naturally coalescing.
The nature of the ecosystem also means that pricing is closely tied to "procurement" which could be routing, limits, whatever at a company level.
If stripe wants to be _the_ one that charges that fee, they either have to continuously try to ensure that all the different middlenen use stripe (most of them do!) but even better is to acquire the largest middleman.
You don't want someone else who happens to do all the routing+limits+policies, end up not using stripe. They already have this hold in existing stripe financial products where they apply all the policies, and everything goes through them.
It is also an easy deal from an investor point of view.
The strategy here is that the same services that Stripe offers for payments have corollaries in the LLM world. Security, user management, perhaps injection attack monitoring, etc.
However I think they dearly overpaid for this as the core technology behind Stripe (fraud detection and integration with global banks) is hard to replicate. Even with the features mentioned above I think the technologies behind OpenRouter are vastly easier to replicate, perhaps even trivial now.
I don't really understand the value -add, so far "smart" routing currently produces worse results at higher cost and static routing can be done yourself trivially. Plus the risk of sending the most sensitive data you have to a third party.
This kind of makes a lot of sense. While my first stake was surprise that a proxy is valued at such a high rate, But it really comes down to the terms if open router is allowed by their terms to see the prompts and responses, Then that's very, very valuable data today for any model improvements and other opportunities that people might be looking for.
I'm surprised OpenRouter went for 7B, while fal.ai just raised at $8b, despite fal having far less traffic (semrush reports ~5x more traffic to openrouter). They seem like very parallel businesses, just with focuses on different models (creative models vs LLMs).
If someone from Stripe / OpenRouter is listening, please let me provide Open Router OAuth to my users and let me take a cut of their usage. Apple takes 30, I would take whatever the users are willing to pay. 5 to 15 is reasonable.
What value are you providing that you'd take some further cut? You could take the money from the user via stripe and then pay your own openrouter bill instead.
I'm still amazed at Apple's 30%, it's just so brazenly high (like: "fuck you, we're Apple, we do what we want and you'll lick it up"). Unfortunately, too, other companies follow Apple's lead, and so this massive rent seeking percentage has become normalised.
I can totally agree that Apple sucks for doing this, but you seem to insinuate they started this. As always Apple wasn’t first not even tenth: Nintendo, Steam, Xbox, Kindle all did it prior to “the platform economy” 3)
yeah, i bet this seems like a good deal in a few years, we'll see. remember Poe haha that was a similar kinda thing but openrouter waited until the market was mature
Free model usage is controlled by the LLM provider, not OpenRouter. Both parties have their own incentives to allow it and that would not change with different owners.
Terrible news for the market. Even as someone who dislikes AI, it's terrible. Stripe is a horrible company and more market consolidation is very worrisome.
Hope someone clones it and they take a loss at it.
I had consistent problems (5 months back) with OpenRouter and other providers. And very hard to debug. I used the provider directly (Google) and worked perfectly.
They do reach out pretty quick when your usage takes a huge dive after you move to one of the single provider plans that offer hard to believe possibly unsustainable value.
Why would PayPal acquiring OpenRouter make it any more of a monopoly than it is? Not saying it is or isn't, but OpenRouter isn't even a financial company.
That's not a very common pattern, to be honest. A bunch of people have been experimenting with automatic model routing recently but mainly as a cost optimization, since tokens for the best models have got expensive once you start piping millions of tokens through them.
I haven't seen much evidence that model routing is being widely used yet. I think it's still more of an experimental mechanism right now.
OpenRouter is a proxy, not an automatic router. Rather than building API clients for five different AI providers, you build one client to OpenRouter, and switching models become extremely easy. This matters when new models are coming out virtually every day.
Dumb question but aren’t they all OpenAI API compliant? I thought that was pretty standard, eg I know Anthropic works with it. Also Claude Code can work with different models, they’re probably not using OpenRouter for that?
Effectively but not quite. Anthropic does mostly support the OpenAI API but there are minor feature gaps. You have to use Anthropic's bespoke API to use everything (which may or may not be important to you).
There are some gotchas with it too. e.g. The "system" role message isn't supported in the Anthropic API. It's not the biggest deal but it's a potential footgun.
On the other hand, the openrouter SDK + API takes care of this for you: Their one gateway has ways of enabling provider-specific features. You can switch the model name and pretty much be good to go.
Claude Code does not work with other models out of the box. You need a wrapper around Claude Code that translates other model requests + respondes to what the harness expects.
All the model companies except kind of Anthropic (and even they half-assedly do) implement the OpenAI API. It's not an open standard but, like the S3 API, it effectively is.
And, to answer your question, no. The existence of a common API makes it trivial to change zero code and send requests to a different model.
The Anthropic messages API is a competing standard (it's just better than the OpenAI API which even OpenAI has moved away from) and some Chinese providers use it as their standard.
It's more complicated than that. Lots of providers use an "OpenAI-ish" API, but many of them have subtle differences in things like tool calling or thinking blocks. OpenRouter normalizes the wire format.
OpenRouter does more than just proxying; they also aggregate providers for open-weight models, which has a stabilizing effect on pricing and gives you protection against a single provider's downtime.
no. i don't know if openrouter even guarantees consistent protocl across models.
the value of openrouter is it offers centralized billing. you can route your calls to any provider you want, test a whole bunch of models against each other, and you just get one bill from openrouter. switching to a new model, or a new provider of the same model, doesn't mean setting up a new billing account with a new provider.
I see, that make sense, thanks for the explanation. Because otherwise I was thinking their whole business model would be just to provide an API tool library.
I think that OpenRouter's goal is to have the user pick the model, so there's manual configuration for the user control and cost benefit. Maybe you meant OpenCode Zen? But let's be honest, "AI" is definitely incredible, not "hilarious", or "so bad".
To people asking why, this is a good lesson on the Collison’s ambitions. Stripe is one of the best API companies in the world. They know how to serve high volumes of latency and availability sensitive requests. They’ve abstracted the financial rails for payments and now want to abstract the rails for LLMs.
They’re the perfect company to own OpenRouter.
Tokens are simply a lightweight valuable asset. Stripe can serve as the middleman as well as anyone. They know how to route to many providers (payment rails) with huge differences in service characteristics. LLM providers are far easier.
Then they can work this into an offering where users can subscribe to tokens and use them across services. It solves one of the core monetization challenges of every AI company: how do you price when your costs are variable on usage, but nobody can make sense of charging by token?
From here, they can start hosting their own models and competing as an AWS for tokens. They can be the best provider of $OPEN_MODEL, or their own, and optimize for you.
You'd be surprised how little volume of api calls payments companies get compared to advertising companies or consumer internet companies. Stripe aren't especially well placed to own this asset on a technical level. That doesn't make this a bad acquisition per se, but there is no magic stripe can inject here as far as infra/technology is concerned.
Agree, even in the payments space usage-billing metrics providers like Chargebee / Lago etc get order(s) of magnitude more data than payment.
Granted payments and associated ledges require a level of consistency that other systems do not require, but that is orthogonal to high volume.
You'd be surprised how antiquainted many of them are. I don't mean Stripe or Braintree but the long tail of terrible terrible credit card processors. If I hear "Chase Payment Gateway" I shudder.
Do people feel Stripe APIs are really that good? I’ve always found them unintuitive, tons of options, weird edge cases, breaking occasionally, etc.
I’m sure payments are convoluted, but I’d still imagine they could be meaningfully easier for the bulk 80% of use case?
Yes, Stripe is extremely good at what they do. Payments are complicated.
Payments themselves are so much complicated. Payments to support multi-currency, jurisdictions, countries, scenarios, that's complicated.
I'm friends with a payment docs writer. Holy crap are payments complicated.
Stripe's APIs are very good. They could be better, but it's difficult to change the underpinnings of financial infrastructure. A lot of risk, little incentive to move, and you're designing something that has to last (and make sense) for 15+ years in the future.

Coincidentally, I had a conversation with a recruiter at Anthropic and saw them doing something very similar. They were starting a new team in a new vertical and wanted someone with experience running an org of 100+ people. I would bet real money that it will be a fraction of the product/impact it could be (though still probably make money!)
I have implemented the Swift payment Spec and I can tell you having this abstracted in a nice API is so much better.
I expect many of the warts in the API surface are there because they want to avoid changing things for fear of breaking someone else's business.
I mean. They used to be good. When they started out their docs were absolutely far above the competition. They aren’t now, and Stripe has lived long enough that they’ve seen themselves become the villain.
Stripe has the worst payment APIs, except for all the others.
Feature bloat definitely made their API and product docs harder than the early days. Stripe Checkout would have saved my teams days, but I agree, they need to go back to their roots and make the 99% use case very easy.

This seems like a stretch given the rise of local inference, especially the Prism Labs rumors from a few weeks ago.
One way I think about LLMs is they are akin to fancy databases in that they are software of which you can ask questions and get answers if you ask properly.

It's been a few years, but I used to work on almost exactly this (not at Stripe, but we processed hundreds of billions annually). If you're a big enough merchant (or Stripe itself), you can choose to send a credit card transaction to any one of potentially many processors, each of which have their own performance characteristics (one may approve at a higher rate, the other may charge better fees, etc). All of this subject to attributes of the transaction itself (ticket size, geography, card type, many others). You know quite a bit about the transaction itself before you send it out, so you can build up routing knowledge to optimize for whatever thing you care about (usually transaction success rates or fees).
See how this starts to look a lot like OpenRouter with money instead of tokens? I'm not sure I 100% believe that's how it'll shake out, but there is a transferable skillset.
> would it make sense for someone to say that their credit card processor just bought the company that makes their ODBC driver? Would anybody suggest that the TPS of their RDS instance is a lightweight asset?
Would is make sense to say that their online bookstore now sells Ethernet cables, bidets, and delivers groceries? Sells _cloud infrastructure_??
Amazon made two transitions:
1. Amazon the online bookseller => Amazon "The Everything Store"
2. Amazon the online retailer => Amazon the Cloud Services company
I believe what Stripe is doing here is closer to (1). "We are good at high-throughput APIs that wrap complexity with thin margins. We did it for credit cards, then ~all payment methods, now other digital bits."
In this context, tokens are much, much easier than international payments.
Now: Is it outlandish for their customers?
Not really. Every engineer knows stripe as an engineering company. I don't think Stripe is what it once was, but it's certainly a generational company. You're asking engineers—who broadly have a positive impression of Stripe—to use this product they already know. OpenRouter gets the positive brand association (trust) of Stripe; Stripe expands into a new domain whose technical needs are extremely similar.
Ok, at first I didn’t get it and thought it would make sense if stripe just wants to build payments for agents, but on a second thought your idea about “once buy tokens — use everywhere” is very good one!
unless it's all just tulip mania, then they just spent $7B on nothing
Here are some things that are abundantly clear to me.
1.) LLMs are useful for programming
2.) Open models are excellent and will continue to improve
3.) Economies of scale and ease of access mean self hosting is out of the question for a large number of users
This means that even if the largest labs are not worth trillions and a large amount of the data center build out is not as valuable as the builders project and GPU/RAM prices plummet, it will not matter at all for this business. People will want to buy cheap open source tokens from a centralized trusted provider.
$7 billion for a business with little overhead that is already within their core competency and has strategic growth potential seems like a very good deal.
What does openrouter actually do though? They buy a bunch of tokens from token providers and allow you to easily route queries between token processors?
This seems like the kind of thing that you can have Claude write in an afternoon for whatever service you're running. I don't see the value.
people are lazy
people don't want to maintain infra (ie adding new models all the time)
people want their queries to work without thinking
if a provider goes down, openrouter queries dont (ideally)
it's really not that complex to understand
Unfortunately we don't really know anything about OpenRouter or Stripe's numbers. They're both private companies. AFAIK there really isn't much information publicly available about how profitable or not OpenRouter actually is, or whether it has a little or a lot of overhead. So I can't really say whether $7B is reasonable or inflated. It seems like an enormous number, and my hunch is like all the other enormous numbers floating around in the AI space it's probably inflated by the hype bubble. But we just don't know.
Broadly I agree with you. It seems like they have an in-demand product and there could be a sustainable business there at least in principle. But whether it's a $7B business or a $70M business I can't say.
depends what the tulips are. tokens? private growth stage shares?
openrouter is involved with a lot of scammy crypto personalities. maybe they are the tulips people have been manic about for too long. maybe the collisons are the tulips.
why did they miss the market that is OpenRouter?
You're asking how someone missed llms. On this website? That demonized them for years and is only now fighting the cultural battle to accept them as useful?
I wonder if this deal is primarily just to buy payment volume.
OpenAI just announced earlier this week that Ayden would become their payment provider (when it was previously Stripe).
And OpenRouter has a large percentage of overall AI payment volume for all the major labs.
Both OpenAI and OpenRouter represent ~$100B in payment volume, whereas Stripe in total doing ~$2T. Two customer doing ~5% of your total volume who didn’t even exist a few years ago, must be kind of scary for Stripe.
https://www.reuters.com/business/retail-consumer/rise-ai-sho...
https://stripe.com/newsroom/news/stripe-2025-update
OpenAI is a large company, and large companies go multi processor for payments. I would check the press release carefully, and see if you can confirm that Adyen is taking all of OpenAI's volume, of even a majority of it.
Adyen just bought Orb [0], a usage-based billing company, for $335M, specifically so they could position themselves as the payments choice for AI companies.
[0] https://www.withorb.com/
Stripe would lock in volume but how exactly are they monetizing that? Any margin the get from OpenRouter is money extracted from OpenRouter’s revenue (which is now theirs.)
7 billion one off for 100 billion annually? If I am understanding that correctly it feels like a no brainer to me…
Also if you think about it differently… OpenRouter is adjacent to what Stripe is but for getting access to AI models. If they dont mess this up they could invest in openerouter and grow that 100b pie.
$100b is payment volume, not revenue. Stripe gross revenue from those payments would be on the order of tenths of a percent of that.
Plus the platform fee that OpenRouter makes? 5 billion a year?
I think volume is itself good and help Stripe negotiate lower rate with banks etc.
> Two customer doing ~5% of your total volume who didn’t even exist a few years ago, must be kind of scary for Stripe.
Shopify uses Stripe no? Probably good volume discount though.
Adyen*
>OpenRouter represent ~$100B in payment volume, whereas Stripe in total doing ~$2T.
That is a much higher % than i expected.
How can a middle man for api calls be worth so much? Their market share can’t be very large right? For comparison, $7B is more than market cap of Lyft, Dolby, and Alaska Airlines. What is happening?
https://stockanalysis.com/list/mid-cap-stocks/
It's an inflated number due to the AI market, but their selling point is distribution.
Many people and businesses want to experiment with different models, but they don't want to sign up for a dozen different services. Businesses can make it difficult to approve new vendors. If your company is looking at 5 different vendors for tokens and teams can't agree to switch together, OpenRouter comes along with a unified interface and a single billing point.
They also become the point to add value-add services on top in a portable way. They already offer some things like automatic JSON repair, but I can see them adding functionality like leak detection tools, monitoring, alerts, and other patterns that a company can set up once and use with all of the models theirs teams need.
What I'm not so sure about is their moat. They have the brand recognition, but it seems rather easy for someone else to build what they've built. I'm a little confused about why Stripe didn't just build the same thing internally. Acquiring this company gives them an instant boost of 10 million customers for their AI business, which might be key to some financial goal they've got.
As a nobody I like OpenRouter because it lets me quickly test out all of the emerging open weight models. I normally use Claude Code but if I run out of usage I'll pull up GLM 5.2 or Deepseek V4 in OpenCode via OpenRouter. Occasionally I'll run Claude's work by a Google/OpenAI model through OpenRouter. If Claude Code becomes too expensive I now know I'll be pretty comfortable with open weight models.

Isn't that ripe for being picked off by aws or azure? Both already have marketplaces where vendors can offer whatever cloud services they want. Both already offer first party inference service, and have contracts with all the stodgy corps where it's "difficult to approve new vendors". Not to mention they have IAM and SSO built in. Good luck bolting that onto a third party vendor like openrouter.
I can actually restrict how much is spent using a sensible user interface with openrouter. That’s a real pain with aws
You don't want to spend 2 hours in the IAM and Role control panels?
Yeah, but at least currently, openrouter has the latest open source options way faster than AWS does.
I'd suspect it's related to the rise of good/cheap Chinese models, and OpenRouter is the best way to use them without jumping through a ton of hoops.
Exactly , not even small startup anywhere in us , eu or nearby will be ok to send data to China, but with open router you can create a no China provider selector with one llm call and start using Chinese llms without paying to vendors a single cent .
What’s the angle for stripe , electrify over tokens exchange is the new money flow , and stripe wants to monetize it. 5% tax on any llm token is an amazing deal
> but with open router you can create a no China provider selector
why on earth would you trust no data is sent to China? just because you clicked a toggle?
Openrouter is very transparent about where your requests are going. Every single one is logged.
You decide the routing if you want.
I trust it because there are at least 7 billion on the line. If it came out that they were violating their contract and sending company secrets to China when they promised they won’t, they would lose literal billions for basically no gain, and possible criminal charges.
Why on earth would you think they are sending data to China after you click that toggle when they have every reason not to?
By that logic, how can you trust OpenAI and Anthropic not to do the same?
For one, openai and anthropic are the top two AI labs and therefore have some reputation at stake. Openrouter is like aliexpress. Any fly-by night vendor can get listed on there.
The Chinese providers also have reputations at stake
Not all reputations are equal.
I prefer using OpenRouter because the money I pay them in premium is far less than the money I lose by not using it on other providers. On OpenRouter, I can switch dollars between models. But for the providers, after evaluating I'm stuck with some number of credits on ones I don't use. This kind of intermediation is actually super useful to me. I must imagine that they can also provide other things that are of value like provider quality measures, ability to swap providers during downtime, etc.
Optionality. This positions Stripe well to compete in AI compute, model development, apps... This is not a simple 1+1=2 merger.
You can't really compare market caps like that. Addressable market or market share is only one piece of the puzzle, and the other companies you mention are in very different kinds of markets, with very different kinds of products, with very different kinds of costs and margins.
A valuation just reflects what someone thinks about the future cash flows of the business.
But yeah, it does feel a bit crazy; unsurprisingly, AI hype affects valuations of AI companies too. On the other hand, I can see the idea that some people might be betting on the idea that the big US labs are bloated and spend too much money, and that the real money is going to be in serving open-weight models, and/or in automatically combining and routing to different models based on the task at hand.
LLM traces are supposedly very valuable. I imagine OpenRouter has one of the most extensive and diverse set of traces in the world.
openrouter prompt and i/o logging is off by default https://openrouter.ai/docs/guides/privacy/data-collection
the providers you route to will of course have their own policies, which openrouter surfaces to you through the webui and api. you can even configure automatic routing to select providers based on your policy preferences.
Oh that's very interesting. Thanks for the link.
If your data is leaking to OpenRouter, how many companies would be OK with that? So I doubt OpenRouter are peeking inside the workloads that flow through their proxy. However, they do publish "Top Models by Task" ranking[1] so maybe you have a point.
[1] https://openrouter.ai/rankings#task-spend
The top models by task is self reported. It’s based on the referrer header or some custom one I forget at this moment.
If you don’t include that it just doesn’t count those tokens.
You could just as easily ask yourself how can a middle man for people finding web pages be worth so much, but here we are, and Google is worth something like $4 trillion, mostly on the back of search.
As it turns out, it's very valuable to be the intermediary between a large number of people who want something and a commoditized market of providers. It's the middleman who captures most of the margin.
Now, AI models are not a commodity yet. But things seem like they might be heading that direction. And in a world where they are, Stripe probably wants to be that guy sitting in the middle.
If any of those companies put Ai into their pitch they too would be worth billions
You've already seen Long Island Blockchain, now get ready for... Alaska AI Lines!
I landscape gardens... With AI.
Pay me.
Cursor got bought for $60B. This is simply how AI companies are valued.
When there is a bidding war for a company, I don’t think fundamentals matter as much anymore..
A good year for Alaska Airlines is 5% sales growth. OpenRouter is growing that much per week I'm guessing.
Their market share is as big as it gets for that type of AI business.
The market cap of any business operating in the physical realm has to account for enormous liability, especially for one like an airline. Also, their operating costs are huge with much less ability to scale, resulting in much lower potential increase in margins.
OpenRouter raised money at a $1.3 billion valuation a few months ago, if the NYTimes reported valuation is accurate.
Going from a $1.3b valuation to a $7b exit in a couple months is an amazing return for those investors. I hope the OpenRouter employees got some decent equity out of this
They should just hold Stripe stock, plus there are always liquidation preferences so it is not so black and white
The reason OpenRouter can build value even if there are 100 clones is switching costs and flexibility. AWS Bedrock may be great for large enterprises, but flexible startups will use OpenRouter for ease, and now they have Stripe's distribution. Once you use OpenRouter, you won't switch because you become embedded in the logs and cost-saving systems.
AWS Bedrock - Microsoft Teams
OpenRouter - Slack
https://s-1.vercel.app/posts/why-openrouter-can-be-the-next-...
A large missing link for AWS Bedrock is Gemini model support [0]. And this is a vital feature, because Gemini itself (as far as I'm aware) does not have a real-time daily or weekly hard spend cap in the case of misconfigured or compromised callers [1][2].
Meta's closed source models, too, are only available on OpenRouter (and it's touted as a first-class recommendation on [3]).
So, in many ways, OpenRouter is the only game in town to access some of the highest-funded model families on the market through a single API endpoint.
I'm unsure why AWS is ceding this territory (there have to be ways to allow users to opt into the lesser governance inherent in using third party providers, while not diminishing the brand's governance requirements). But, since they are, it's a meaningful opportunity left open.

Well, you have the logs and specific cost control measures and setups in place. You would lose all that in the event you attempted to switch, plus Stripe owning OpenRouter gives them stronger distribution and further solidifies the switching costs in the broader integrated solution Stripe offers - https://s-1.vercel.app/posts/what-stripe-can-become-broader-...
Historically acquisitions have never really been good for customers. Time for me to look for an OpenRouter alternative? At least they're also as easy to switch from as the model providers they proxy.
No, Stripe's mega plan is to create a consolidated internet offering for internet-first businesses, not price gauging, the masterminds behind this are not corporate suits, rather founders that deeply understand business strategy - https://s-1.vercel.app/posts/what-stripe-can-become-broader-...
Stripes founders aren't suits but they're just as eager to make money. Their payments business is low margin and they're hungry for anything higher margin they can attach.
Yeah, Amazon didn’t let its low margin retail business prevent them from taking high margins in AWS. I’m not sure why it is assumed Stripe would stay low margin.
Well, they should be motivated by profit, especially if they can create an integrated solution, the convenience means everybody wins.
I don’t think you understand just how much money Stripe currently makes.
Doesn’t make them high margin, though.
Margin is not necessarily important. You would much rather be Amazon and take 50% of e-commerce at a small margin than be a SaaS with 80 +, but your market is inherently tinier.
Plus, the ads business built on top of retail is better than AWS and retail. AWS is great, but ads is higher margin, grows with retail, and is something you see across so many aggregators.
https://s-1.vercel.app/posts/marketplaces-airbnb-future-foun...
Everyone seems to be asking why this a great strategic fit for Stripe.
Stripe can now provide tools to every product that sells metered AI usage and take a cut. This isn't about extracting a small percent on the tokens flowing from your coding agents to your model of choice. It's about all the products that are going to come to market and monetize metered usage.
Want to analyze your 2026 tax return? Use VisorAI's Tax Agent and pay only for what you use. Stripe provides all the accounting, payment processing, ships money to vendors, and takes a bit off the top. Trillions of dollars moving from the labor market to the token market? It's $10B per point in fees for every trillion.
Congrats to the OpenRouter team.
I vividly remember back in 2023/2024, I was sitting on my sofa thinking, "there has to be a market to abstract data access layer, something like Terraform but for LLM provider to avoid vendor lockin". Only if I had access to capital to build something like that at that time, I could have been my try for an AI start up.
> Earlier this year, Atallah described OpenRouter as the AI equivalent of Stripe.
Not sure I understand how this is strategically aligned for Stripe but certainly an interesting comparison.
OpenRouter uses Stripe to handle payments [1], so this acquisition hopefully will reduce OpenRouter's cost while increasing Stripe's revenue.
[1] https://stripe.com/newsroom/news/openrouter-and-stripe
> Every company in the Forbes AI 50 that monetizes does so on Stripe.
That’s chilling.
Stripe started as a result of the PayPal Mafia.
"In 2011 the company received a $2 million investment, including contributions from Elon Musk, PayPal founder Peter Thiel" [1].
Also fun fact from the Founder's Wikipedia page
"In November 2024, Collison was criticized for visiting Israel and posting an image with the Israeli flag,[31] amid the Gaza war."[2]
[1] https://en.wikipedia.org/wiki/Stripe,_Inc. [2] https://en.wikipedia.org/wiki/Patrick_Collison
Stripe seems to appear to be attempting to compete with the US Federal Reserve as the core dollar payment processor while also dipping into the same for tokens. Core value exchange platform, dollars, tokens, whatever. A bit of a less exciting version of Dune. “The transaction volume must flow.”
Perhaps the US State Dept. used it's strong relationship with Stripe to encourage this purchase as a geopolitical move. They've done so before with companies like eBay and Microsoft to neuter the P2P telephone access network that was "Skype".
Yea they love centralized brokers, exchanges, etc.
Both are in the business of putting a single API key in front of a fragmented ecosystem and charging a convenience fee. This middleman business is naturally coalescing.
The nature of the ecosystem also means that pricing is closely tied to "procurement" which could be routing, limits, whatever at a company level.
If stripe wants to be _the_ one that charges that fee, they either have to continuously try to ensure that all the different middlenen use stripe (most of them do!) but even better is to acquire the largest middleman.
You don't want someone else who happens to do all the routing+limits+policies, end up not using stripe. They already have this hold in existing stripe financial products where they apply all the policies, and everything goes through them.
It is also an easy deal from an investor point of view.
The strategy here is that the same services that Stripe offers for payments have corollaries in the LLM world. Security, user management, perhaps injection attack monitoring, etc.
However I think they dearly overpaid for this as the core technology behind Stripe (fraud detection and integration with global banks) is hard to replicate. Even with the features mentioned above I think the technologies behind OpenRouter are vastly easier to replicate, perhaps even trivial now.
Congrats to all parties. Makes me more likely to use openrouter and excited for where stripe is heading.
I don't really understand the value -add, so far "smart" routing currently produces worse results at higher cost and static routing can be done yourself trivially. Plus the risk of sending the most sensitive data you have to a third party.
Even ignoring routing, it's still very 'nice' to be able to buy almost any model in one place.
Amazing for enterprises, or companies who are letting users choose from a variety of models for ai tools.
I don't think you understand what Openrouter's product is.
This kind of makes a lot of sense. While my first stake was surprise that a proxy is valued at such a high rate, But it really comes down to the terms if open router is allowed by their terms to see the prompts and responses, Then that's very, very valuable data today for any model improvements and other opportunities that people might be looking for.
Does this mean they will be censoring openrouter?
Is there an open source alternative for when the censoring begins?
I'm surprised OpenRouter went for 7B, while fal.ai just raised at $8b, despite fal having far less traffic (semrush reports ~5x more traffic to openrouter). They seem like very parallel businesses, just with focuses on different models (creative models vs LLMs).
LLMs have zero margin.
Media models have crazy margin.
Have you seen FAL's pricing? It's absurdly marked up. 50% or more.
Ramp LLM Router Stripe LLM Router(?)
What’s up with finance companies getting into LLM routers?
They have the unique advantage of seeing where money is flowing and are positioning for the most likely future based on their analysis.
If someone from Stripe / OpenRouter is listening, please let me provide Open Router OAuth to my users and let me take a cut of their usage. Apple takes 30, I would take whatever the users are willing to pay. 5 to 15 is reasonable.
For the first part they have https://openrouter.ai/docs/guides/overview/auth/oauth (which I haven't used). That gives you an openrouter key for that user (openrouter bills the user).
What value are you providing that you'd take some further cut? You could take the money from the user via stripe and then pay your own openrouter bill instead.
I'm still amazed at Apple's 30%, it's just so brazenly high (like: "fuck you, we're Apple, we do what we want and you'll lick it up"). Unfortunately, too, other companies follow Apple's lead, and so this massive rent seeking percentage has become normalised.
I can totally agree that Apple sucks for doing this, but you seem to insinuate they started this. As always Apple wasn’t first not even tenth: Nintendo, Steam, Xbox, Kindle all did it prior to “the platform economy” 3)
I mean, the problem isn’t the rent seeking. It’s the licking it up part.
I'll save you $7b.
https://api.anthropic.com https://api.openai.com/v1
As an openrouter user this is better than most alternatives I guess
Le sigh.
The enshitification will be inevitable. Soon this wonderful resource will no longer exist.
yeah, i bet this seems like a good deal in a few years, we'll see. remember Poe haha that was a similar kinda thing but openrouter waited until the market was mature
We buying inflation burritos with tokens ain't we
RIP free deepseek access.
Free model usage is controlled by the LLM provider, not OpenRouter. Both parties have their own incentives to allow it and that would not change with different owners.
The free DeepSeek depended on full data sharing straight to China.
Le sigh.
The enshitification will be inevitable.
Back to my own brain for my coding projects.
Terrible news for the market. Even as someone who dislikes AI, it's terrible. Stripe is a horrible company and more market consolidation is very worrisome.
Hope someone clones it and they take a loss at it.
Also someone start counting days until they implement mandatory KYC and AML into request processing.
I had consistent problems (5 months back) with OpenRouter and other providers. And very hard to debug. I used the provider directly (Google) and worked perfectly.
OpenRouter should first fix their support.
No support exists when things go wrong!
They do reach out pretty quick when your usage takes a huge dive after you move to one of the single provider plans that offer hard to believe possibly unsustainable value.
This is even before them acquiring PayPal. If Stripe bought PayPal in 2022, it would be immediately blocked. Not this time.
One of the only near monopolies that is seemingly allowed and it is even praised.
But who cares. Nothing to see here (as long as AGI is coming it doesn't matter anyway).
Why would PayPal acquiring OpenRouter make it any more of a monopoly than it is? Not saying it is or isn't, but OpenRouter isn't even a financial company.
I am saying it is a near monopoly as Stripe is the one that is close to acquiring PayPal in the first place. [0]

I still find it hilarious that AI is so bad you need something to sit in front of it to pick models for you. And that's a normal, accepted thing.
That's not a very common pattern, to be honest. A bunch of people have been experimenting with automatic model routing recently but mainly as a cost optimization, since tokens for the best models have got expensive once you start piping millions of tokens through them.
I haven't seen much evidence that model routing is being widely used yet. I think it's still more of an experimental mechanism right now.
OpenRouter is a proxy, not an automatic router. Rather than building API clients for five different AI providers, you build one client to OpenRouter, and switching models become extremely easy. This matters when new models are coming out virtually every day.
Dumb question but aren’t they all OpenAI API compliant? I thought that was pretty standard, eg I know Anthropic works with it. Also Claude Code can work with different models, they’re probably not using OpenRouter for that?
Effectively but not quite. Anthropic does mostly support the OpenAI API but there are minor feature gaps. You have to use Anthropic's bespoke API to use everything (which may or may not be important to you).
There are some gotchas with it too. e.g. The "system" role message isn't supported in the Anthropic API. It's not the biggest deal but it's a potential footgun.
On the other hand, the openrouter SDK + API takes care of this for you: Their one gateway has ways of enabling provider-specific features. You can switch the model name and pretty much be good to go.
Claude Code does not work with other models out of the box. You need a wrapper around Claude Code that translates other model requests + respondes to what the harness expects.
Does that means if by any chance all frontier model companies agrees to use an open protocol for the API open router would go out of business?
All the model companies except kind of Anthropic (and even they half-assedly do) implement the OpenAI API. It's not an open standard but, like the S3 API, it effectively is.
And, to answer your question, no. The existence of a common API makes it trivial to change zero code and send requests to a different model.
The Anthropic messages API is a competing standard (it's just better than the OpenAI API which even OpenAI has moved away from) and some Chinese providers use it as their standard.
It's more complicated than that. Lots of providers use an "OpenAI-ish" API, but many of them have subtle differences in things like tool calling or thinking blocks. OpenRouter normalizes the wire format.
OpenRouter does more than just proxying; they also aggregate providers for open-weight models, which has a stabilizing effect on pricing and gives you protection against a single provider's downtime.
no. i don't know if openrouter even guarantees consistent protocl across models.
the value of openrouter is it offers centralized billing. you can route your calls to any provider you want, test a whole bunch of models against each other, and you just get one bill from openrouter. switching to a new model, or a new provider of the same model, doesn't mean setting up a new billing account with a new provider.
I see, that make sense, thanks for the explanation. Because otherwise I was thinking their whole business model would be just to provide an API tool library.
I think that OpenRouter's goal is to have the user pick the model, so there's manual configuration for the user control and cost benefit. Maybe you meant OpenCode Zen? But let's be honest, "AI" is definitely incredible, not "hilarious", or "so bad".
I don’t think it “being bad” is the motivation. It’s about saving money and pooling cheaper resources.
>I still find it hilarious that AI is so bad you need something to sit in front of it to pick models for you. And that's a normal, accepted thing
My lord. Of all the terrible, uniformed takes the HN posters are spewing, this is the worst one I've seen in a while.
The anti-AI crowd really are clueless, eh?
No, you don’t. But most have fomo and use them.
