Love walking up to Omabot emailing me about work it's done overnight. @patrickc suggested adding Ori as an agent option last night, connected me with OpenRouter CEO @alexatallah, and I kicked off Omabot to do the work. We'll ship to edge today. THE FUTURE IS AWESOME! https://t.co 51K views · 450 likes · 11 reposts · 35 replies Open on X →

10/ Stripe brings a large customer network, data on how internet businesses grow, and years of experience running trusted global infrastructure.

8/ Stripe is that company. They are the best financial infrastructure platform in the world. Their API set the standard that developer products, including ours, have been measured against ever since.

9/ For years, OpenRouter has been called “Stripe for LLMs.” Both companies share common DNA: we abstract complex infrastructure and market dynamics into delightful APIs, and we obsess over the developer and user on the other side of it.

6/ We envision a healthy AI ecosystem where many models thrive, where AI neurodiversity is a strength, where a lab or an inference provider with a breakthrough can reach millions of developers, and where no single model becomes the default by inertia.

4/ OpenRouter exists to give users every model on equal footing, provide open signals about how they’re used in the market, help developers orchestrate them together, and make them observable and manageable at scale.

1/ Stripe has signed an agreement to acquire OpenRouter. OpenRouter will continue to operate as it is: same name, same product, same roadmap, same mission.

OpenRouter is joining Stripe: https://t.co/hiH0kDB3hG. As anyone who uses it knows, @OpenRouter is a truly delightful developer tool. It is by far the best way to use new models and manage multiple inference providers.
