### Adaptive Thinking
:::note
When using `reasoning_effort` with Claude Opus 4.7, all values (`low`, `medium`, `high`, `xhigh`, `max`) are mapped to `thinking: {type: "adaptive"}`. To use explicit thinking budgets with `type: "enabled"`, pass the native `thinking` parameter directly.

### Effort Levels
Claude Opus 4.7 supports five effort levels: `low`, `medium`, `high` (default), `xhigh`, and `max`. These give you finer-grained control over how much reasoning the model applies to a task. Pass the effort level via the `output_config` parameter.
Claude Opus 4.7 supports four effort levels: `low`, `medium`, `high` (default), and `xhigh`. These give you finer-grained control over how much reasoning the model applies to a task. Pass the effort level via the `output_config` parameter.
`xhigh` is a new effort level introduced with Opus 4.7 that sits between `high` and `max`. `max` is available on Claude Opus 4.6 and 4.7 only.
`xhigh` is a new effort level introduced with Opus 4.7 that sits above `high`. The `max` effort level is Claude Opus 4.6 only and is not available on 4.7.
