Fable 5 always uses adaptive thinking and defaults to `high` effort. `/think off` and `/think minimal` use `low` effort because the model does not support disabling thinking. ## Claude Sonnet 5 Use `anthropic-vertex/claude-sonnet-5` with Vertex's `global`, `us`, or `eu` endpoint. Sonnet 5 defaults to adaptive thinking at `high` effort and supports `/think off` or the native `/think xhigh|max` levels. OpenClaw publishes its 1,000,000-token context window and 128,000-token output limit automatically. Catalog pricing follows Vertex's introductory global rate of `$2/$10` per million input/output tokens through August 31, 2026, then `$3/$15` from September 1. The `us` and `eu` multi-region endpoints use Vertex's documented 10% premium.
