RouteLens is a Node.js diagnostic tool for Microsoft Foundry Model Router. It sends configurable prompts through two Azure OpenAI runtime paths (Chat Completions and Project Responses), logs every response to JSONL, and surfaces differences in model routing decisions, latency (p50/p95), throughput (tokens/sec), and error rates.
Track the latest model releases on Microsoft Foundry — with a changelog of announcements plus runnable capsules (README + notebook) per release, organized by publisher.
Add a description, image, and links to the foundry-models topic page so that developers can more easily learn about it.
