Weave Router directs AI requests to cheapest model — saves 40% on costs
Weave has built an intelligent router that sends coding requests to the most appropriate AI model based on task complexity. The system uses RL-training on thousands of agent-traces to determine when expensive frontier models like Claude Opus are needed and when cheaper alternatives like DeepSeek or GLM are sufficient — achieving 40% cost savings without quality loss.
WHY IT MATTERS
Cost control becomes critical as AI becomes standard tooling for development. Intelligent model routing sets a new standard for how to optimize LLM usage in production, and the idea is generalizable far beyond coding agents.
