GoKawiilWeave Router 2.0 matches GPT-6 Astra performance at half the cost
Weave OS released Weave Router 2.0, an open-source model router that dynamically switches between LLMs for coding agents like Claude Code or Codex. On Terminal Bench 4.0 and SWE Atlas benchmarks, the router matched GPT-6 Astra's pass rates while running at roughly 52-54% of its cost and 2.2-2.5x faster. The company attributes the gains to a new routing architecture, a larger training dataset, and improved cache-eviction calculations.
