OpenRouter adds :nitro fastest-provider routing
AI summary
OpenRouter is promoting its :nitro suffix on X: appending :nitro to any model slug routes a request to whichever provider is currently serving that model fastest. In a demo using DeepSeek V4.1 Flash, described as its most-used coding model, the same prompt reportedly took 6.8s without :nitro and 3.9s with it. The figures come from a post the OpenRouter account reshared, so they are vendor claims rather than independently verified results.
In-depth insight
Developers can get faster inference without changing code, though speed-first auto-routing may trade off against other provider attributes.
