Summary: A Show HN posted workweave/router, a model router for agentic systems that selects a model per prompt in under 50 ms and integrates with Claude, Codex, and Cursor through an endpoint change. The project claims 40 to 70 percent cost reduction; the figure is the author's own and unverified. The repository has about 287 stars.
Why it matters: Per-prompt model routing is a common cost lever for agent harnesses, but the savings claim needs independent measurement.
