Weave Engineering Intelligence launched Weave Router 2.0 to route coding agent requests across Claude and GPT models based on what’s available. On Terminal-Bench 4.0 and SWE-Atlas, it matched GPT-6 Astra at half the cost. It now uses a task-complexity and quota-aware classifier to switch models only when estimated savings exceed the rebuild cost.

In other words, the stack is getting more careful about where code runs and what it can do, because the outside world is increasingly saying no.
