@iamzhe says minirouter/fusion is live: it classifies each request with TypeSafe Jev, then routes to a model matched to type and complexity. Codex lists their presets and routers in the model picker. They also fixed long prompts not caching automatically in Claude Code.

Codex lists their presets and routers in the model picker. They also fixed long prompts not caching automatically in Claude Code. Small update for https://t.co/xXR4JLt377 today: 1. minirouter/fusion is live. It classifies each request with Jev by @typesafeai, then routes to a handpicked model matched to the task's type and complexity. How Jev or TypeSafe is used, in the post's own words: “It classifies each request with Jev by @typesafeai, then routes to a handpicked model matched to the task's type and complexity.” The post does not name a separate audience. It is for people reading what @iamzhe shows here (it links to minirouter.sh; it includes media).
