OpenRouter Launches Next-Generation Model Routers Auto Router and Auto Code
OpenRouter has released a new generation of model routers, including Auto Router for general Q&A and agents, and Auto Code for coding agents. The company claims that Auto Code's benchmark performance is close to Opus 5.5, at 74% lower cost, with p90 latency of only 0.65s; during testing, compared with the previous-generation router, invalid tool calls were reduced by 4x, agent response truncation decreased by 50%, and latency was reduced by 3x. The new routers support showing the basis for routing decisions on a per-request basis, and will still seek the most cost-optimal option when the model list is restricted.

Real world, not just benchmarks.
In our beta, we observed 4× lower invalid tool calls, a 50% reduction in cut off agentic responses, and 3x lower latency vs the previous router.
With built-in feedback loops, the more people who use OpenRouter, the better it will get.
