Switch friction
- Provider overlap exists on Novita AI; start route-level A/B tests there.
- Cheapest tracked output pricing is tied, so migration risk shifts to quality, latency, and provider packaging.
- Check replacement coverage for Structured outputs and Code execution before moving production traffic.
- Qwen3.6-35B-A3B adds JSON / Tool use in local capability data.
