A stealth reasoning model dubbed Ox Alpha just dropped for free on OpenRouter, sending AI circles into a frenzy over who actually built it. Designed for heavy coding and sustained agentic workloads, the model earned high praise from Stripe CEO Patrick Collison. Theories on its origin currently point to Chinese lab Z.ai or Microsoft's unreleased MAI.
Stripe just confirmed it's acquiring AI model routing startup OpenRouter for a reported $7.5 billion, a massive jump from its $1.3 billion valuation in May. OpenRouter connects 8 million developers to over 400 AI models. Why it matters: Beyond processing payments, Stripe is buying a front-row seat to AI token spending and developer demand.
OpenRouter just rolled out Fusion, an API feature that queries multiple models in parallel, adds web search, and synthesizes a final response using a judge model. In testing, a budget panel of three smaller models scored nearly on par with Anthropic's flagship Fable 5 at roughly half the cost. It effectively turns model diversity into a plug-and-play research team.
MiniMax just launched M2.7, a reasoning-focused model that autonomously handled 30% to 50% of its own reinforcement learning workflow, including debugging and metric analysis. It hit a 66.6% medal rate on MLE Bench Lite and scored 56.22% on SWE-Pro. Why it matters: it marks an early shift toward recursive self-improving agent architectures, available now via API.
