One endpoint. Every model. Always the right one. A drop-in proxy for Anthropic, OpenAI, and Gemini that picks the best model for every request: using a tiny on-box embedder, not a vibes-based prompt. Built by Weave: The #1 engineering intelligence platform, loved by Robinhood, PostHog, Reducto, and hundreds of others. Point Claude Code, Codex, Cursor, or your own app at localhost:8080. The router: - 🎯 Routes per request. A cluster scorer derived from Avengers-Pro 1 picks the right model from your enabled providers, every turn. - 🔌 Speaks everyone's API.

Community take
Routing between models breaks prompt caching, likely offsetting per-token cost savings and making the system more expensive overall.
