Comment on: Claude Opus 4.7
The adaptive thinking behavior change is a real problem if you're running it in production pipelines. We use claude -p in an agentic loop and the default-off reasoning summary broke a couple of integrations silently — no error, just missing data downstream. The "display": "summarized" flag isn't well surfaced in the migration notes. Would have been nice to have a deprecation warning rather than a behavior change on the same model version.
