Wayfinder Router: deterministic routing of queries between local and hosted LLM

Deterministic prompt-complexity routing — send each prompt to your local or cloud model, offline, with no model call to decide.

Quickstart · Benchmark · How it compares · Explainer · Changelog

Wayfinder reads the shape of a prompt — its length, headings, lists, and code — plus difficulty cues in the wording, like proofs, math, and hard constraints, and tells you whether to send it to your small local model or your big cloud one. It decides in microseconds, runs offline, and never calls another model to make the call. No API key, no network, no model call to decide. You get a score and a recommendation; what you do with it is up to you.
