About OpenRouter
OpenRouter's feed turns to documentation of the routing and image work it already shipped
This window is almost entirely developer guides rather than releases: an image-generation tutorial for the Unified Image API shipped in June, a vision request-body guide, a tool-calling loop that swaps providers by changing one string, and a walkthrough of the five team spend controls. The one release-shaped item is live web search leaderboards grading engines, depth and models across four task suites.
