OpenRouter is basically a payment system for LLM tokens. Yes, it does route TCP connections from you to an inference providers' cloud, too, but what is way more important is that it routes money from your wallet to inference providers'wallets.
The latter is the core business of Stripe. For them, buying OpenRouter to become the premier channel for LLM token money makes perfect sense. At least if you assume that the current state of labs offering heavily subsidized subscriptions directly is only temporary and the future lies in people buying tokens and switching between models fluidly - and I consider that the future, in light of the recent developments with Kimi K3.
I had assumed they’re just reselling inference, where they’re “routing money” the way Walmart is “routing money” from my wallet to whoever makes Cheez-Its.
Are they doing something unique from resellers there?
They are reselling inference. That is not a novel concept, indeed, a stationary merchant like Walmart does conceptually the same. Although since inference doesn't require any stockkeeping, I would rather compare it to Amazon Marketplace.
But it's been novel for inference services when OpenRouter was founded. And nowadays they have a considerable foothold in the market. There are competitors, but the one everyone knows is OpenRouter.
And since they do not need to maintain any stock, don't need to do anything with queries but route them through 1:1, the most complex thing they do from a business perspective is that they collect your money and route the right amounts to various inference providers that served you.
Not sure how I feel about this. I'm a fan of OpenRouter; it's a super convenient way to work with a bunch of different model providers. Good usage tracking etc. as well.
If Stripe acquires them, I worry that they'll slowly destroy the service, like they did with LemonSqueezy 2 years ago.
As Visa/MasterCard stock price is partly a reflection of the economy at large, I suspect Stripe wants their company valuation to be a reflection of the AI economy.
See projects.dev by Stripe. My best hunch is - Stripe wants to get in on the infrastructure/rails layers being built for AI. They aren't sure what that is going to be exactly (nobody does). OpenRouter seems like a safe bet.
OpenRouters moat is that a) everyone knows it, but not their gazillion competitors, and b) their API URLs and key are already configured in your OpenCode/Oh-my-Pi/whatever harness or agent you use.
As long as they offer stable services and do charge the same API prices as competitors (or even less maybe, since they have the most inference providers on board, because OpenRouters' prime popularity also exists with inference providers) you do not really have an incentive to go through the hassle of changing all your configurations.
What you just wrote isn't a moat at all. One is marketing, the other is a find/replace.
A "moat" is something that protects your product that is really hard to overcome. Like a migrating your database to another vendor, for instance... Or finding your friends and the people you follow on another social media service.
