The Extractions API is now live in alpha on OpenRouter. Use it to pull specific details out of text, images, and PDFs by describing the fields you need, like the names in an email or the total on a receipt, and get each one back as structured data. Read the guide: openrouter.ai/blog/announcem…

Some other OpenRouter ships today: → A new homepage! openrouter.ai → Router rankings page: openrouter.ai/rankings/route… → Live 7-day analytics on the new Auto Router's model usage: openrouter.ai/openrouter/aut… We are just over 100 people now and hiring all over the place: openrouter.ai/careers
OpenRouter is officially part of Stripe! No single lab will build all the intelligence the world needs. We’re building OpenRouter so every developer and business can choose the best of it, wherever it comes from. Every model stays on equal footing. With Stripe, we can bring that choice to the millions of businesses that run there. Long term, we aim to connect the rails that move the economy’s money with the rails that move its intelligence, and build the best developer experience for both.

It’s official! Excited for what’s next.
OpenRouter is officially part of @stripe today! More than 10 million developers and companies use OpenRouter, and as they build with more models across more workloads, they need control over what it costs and where their data goes. OpenRouter has built that operating infrastructure to help run AI across every model and provider, with access to new models, uptime through outages, and enforced spend and data policies for each team. Joining Stripe, which has spent years running critical infrastructure for businesses around the world, means we can build it faster and support companies at every scale. Our commitment to neutrality stays the same. Models and providers compete on quality, reliability, and price. You decide what works for your business.

Companies & users spending $100+/mo on OpenRouter now use a median of 6 model families, double a year ago. A thread & video on model neurodiversity, and why it's accelerating 👇

Our new routing algorithm dramatically raises the floor for inference on open-weight models. Early head-to-head results vs. the old router: ~20% faster time to first token ~20% higher throughput ~40% fewer fallbacks ~60% fewer rate-limit errors
We just shipped our biggest improvement to our provider router since the founding of OpenRouter. Before, we prioritized mostly based on price. The new router now rewards the best quality inference for the actual cost of a request, so requests stay cheap but are also fast and reliable. Providers that deliver more value automatically win more traffic, so every provider has a reason to keep improving. And every time a provider gets better, so does your inference on OpenRouter.

Proud to work at OpenRouter. Now more than ever we need many voices, perspectives, and intelligence. The future is multi-model.
The biggest lie in AI is that the future belongs to one winner. Every technology wave starts with one company promising that one walled garden is all you'll ever need. And every time, market forces and creativity break the walls down. I cofounded OpenSea and now OpenRouter around the opposite bet: humanity will refuse to be locked in. Intelligence was never meant to belong to one lab, one model, or one gatekeeper. The future of AI is open, plural, and yours to choose.

Reminder to check our Security Center to audit your API keys. The AI platform hacks around the internet yesterday were mostly targeting LLM API keys, which have liquid black markets that been developing for years. Startups storing crypto wallet keys will also be at risk.
Today we're launching the first-ever gateway Security Center. @OpenRouter now lets you audit all your keys in one place, see which ones are safe to remove, browse keys by level of risk, and control an IP allowlist.

Don’t know what I’m more happy about..getting to work with @Codydearkland again, or that @Railway agents just got more models to pick from. ✨✨
We're adding @OpenRouter support to Priority Boarding users in Railway @OpenRouter lets you access wider models for all things agent, whether its our harness in a Cloud Agent, or our bots. Models like @grok 4.7, @Muse Spark 1.3 and more What models do you want next?

We audited our own OpenRouter account and found 1,000+ active API keys for 85 employees. Many hadn’t been used in months. 🫣 So we built the Security Center. It shows every key across your workspaces and flags which ones are risky and why. You can disable, archive, or cap up to 500 at once.

What is a decision model? Jev by @typesafeai answers yes/no and multiple-choice questions, with a confidence score. Much of software development are a sequence of decisions, and Jev is 10x cheaper and faster than an LLM. Let’s understand this through practical examples:

Code mode's having a moment (some more litigiously than others). We're building it into Seer @sentry. It's faster, cheaper & acts for you. Pointed it at 54 JS issues → triaged them all, clustered dupes, archived the 20 noisy ones with a comment each. Shipping soon 😇

Every app has a long tail of bugs. Seer is quietly clearing them from the @sentry CLI — 11 last week. First to fall: sentry alert issues view crashed with a TypeError when a rule had no conditions. Seer shipped the guard. → github.com/getsentry/cli/pul…

Finally enabled Sentry + Cursor automation last night. Woke up this morning to around 30 PRs to review, but once I get through this initial wave of error log noise, the implications are pretty incredible; a fully self-debugging and self-healing application.
