Keep request-level `reasoning.effort` unchanged to preserve the prompt prefix for caching. Check the [compatibility limits](https://developers.openai.com/api/docs/guides/reasoning#change-reasoning-mid-conversation) before adopting this feature.207- **Changing reasoning effort:** If your application changes effort between responses, use `configuration_update` items in standard, single-agent requests.
