Model Routing
What I built
Provider interfaces, model routing/pins, fallback, circuit state, budgets/rate limits, caching, streaming and observability.
Result
Implemented provider routing, fallback, streaming and caching. A recorded 40-request replay served 17 cache hits; latency and reference-cost conditions are documented below.
Evaluation setup and selected results
A recorded 40-request live replay served 17 cache hits and made 23 model calls. The implementation includes routing, fallback, streaming and observability. Cache-hit counts describe avoided calls; they do not establish an end-to-end latency or billed-cost reduction.

About the evidence
Based on source review and saved project artifacts. Recorded measurements apply to the stated model, dataset and configuration; they are not claims of a current production deployment.
