Weave reads every turn your agent takes and sends it to the cheapest model that’ll get it right — saving the frontier ones for when it counts.

Cost and time are per trial. Quality is pass@2: a task counts if either of two attempts passed. Router and Astra are paired; OpenRouter is a separate run on the same tasks and graders. Charts share a scale within each metric.

How it works

Most routers answer one question. This one answers four.

From the blogWeave Router 2.0: Astra quality at half the cost

  • How hard is this turn?

    A complexity classifier trained on 10× the sessions of 1.0 scores it in single-digit milliseconds.

  • Will switching cost more than it saves?

    Cache-aware. It only routes down when the saving beats the cost of rebuilding the cache.

  • Is the cheap model actually finishing?

    An escalation classifier watches the task. Stall, loop, or miss → back to a frontier model.

  • Which subscription has quota?

    Claude inside Codex. GPT inside Claude Code. It drains the flat-rate seats you already own first.

Integration

Your tools stay the same.

One command detects Claude Code, Codex, and Cursor and configures each. Add the keys or subscriptions you want to route across.
