OpenAI builds and deploys advanced AI models like GPT-4o for autonomous agents and workflows.
Weave Router
About Weave Router
Weave Router dynamically selects the most cost-effective AI model for each step of an agent’s workflow while reserving higher-quality models for critical tasks. It evaluates task complexity, cache costs, and model performance in real time to route requests efficiently. The system includes classifiers that assess task difficulty, monitor for stalls or loops, and prioritize subscriptions with available quota. Benchmarks indicate it solves tasks faster and at lower cost than comparable routers, with performance measured across standardized coding and QA tasks. Integration is handled via a single command that detects supported IDEs and configures routing automatically. The tool is designed for teams using AI agents in software development workflows.

Frequently asked questions about Weave Router
What does Weave Router do?
Weave Router dynamically selects the most cost-effective AI model for each step of an agent’s workflow, routing requests to cheaper models when sufficient while reserving higher-quality models for critical tasks.
Who is Weave Router designed for?
The tool is designed for teams using AI agents in software development workflows, particularly those seeking to optimize costs and performance in coding and QA tasks.
How does Weave Router integrate with existing tools?
Integration is handled via a single command that automatically detects supported IDEs like Claude Code, Codex, and Cursor, and configures routing without requiring changes to existing workflows.
What classifiers does Weave Router use?
It uses a complexity classifier to assess task difficulty in milliseconds, a cache-aware classifier to evaluate cost savings, and an escalation classifier to monitor for stalls, loops, or missed completions.
Does Weave Router prioritize subscriptions with available quota?
Yes, the system prioritizes subscriptions with available quota, draining flat-rate seats before routing to other models.
How does Weave Router measure performance?
Performance is measured across standardized coding and QA tasks, with benchmarks comparing task completion speed, cost, and quality against alternatives like Astra and OpenRouter.
