Show HN: Open-source model routing for coding agents at Astra-level performance
Summary
Show HN discusses an open-source model routing system for coding agents, featuring Weave Router 2.0 which alternates between LLMs to improve cost and speed. The post details architectural advances (hidden Markov model with bucketed model selection), increased training data, and smarter cache-eviction to beat frontier models on multiple benchmarks. The project is open source and includes hosted options for testing.
