claude-smart-router

Switches Claude Code to the right model for every prompt with a sub-millisecond local classifier.

claude-smart-router

Claude Code uses one model for everything, so simple questions burn the expensive model and hard ones can land on the cheap one. Classifying each prompt with another model call adds ~800ms to every message.

claude-smart-router classifies locally instead, in under a millisecond, from prompt length, keywords, code blocks, file references and numbered steps — zero API calls, zero added cost.
