tiershift: policy-bounded LLM cost router

Jev scores each request on eleven dimensions (difficulty, stakes, safety and more) and YAML thresholds map the scores to model tiers; TypeScript and Python SDKs plus an HTTP proxy.

Notes

~180 ms routing decision; flagship quality at 40% lower cost on 120 prompts ($7.95 versus $13.23 per 1k), $0.04 per 1k routing overhead.
