- Model name change from "roo/sonic" to "grok-code-fast-1" across both providers
- Updated xAI model list with new Grok-4, streamlined Grok-3 models, and removed beta/legacy models
- Added information about prompt caching support and free access through Roo Code Cloud

The prompt caching section lacks sufficient detail about how to use this feature. Consider adding information about how to enable prompt caching or reference relevant documentation for implementation details.
| Prompt caching is available for select Grok models including `grok-4`, `grok-3`, `grok-3-fast`, `grok-3-mini`, and `grok-3-mini-fast`. This feature can reduce costs and improve response times. | |
| To enable prompt caching in Roo Code, set the `prompt_caching` parameter to `true` in your model configuration. For example: | |
| ```json | |
| { | |
| "provider": "xai", | |
| "model": "grok-4", | |
| "prompt_caching": true | |
| } |
If you are using the Roo Code SDK, refer to the Roo Code documentation for implementation details and advanced configuration options.

| The "roo/sonic" model is being renamed to **"grok-code-fast-1"** (officially "Grok Code Fast"). The model will be updated by **August 29th**. This is the same powerful coding model, just with its official xAI name. The model remains **free** when accessed through Roo Code Cloud during the promotional period. |

The hardcoded date 'August 29th' will become outdated after the transition. Consider either removing the specific date after the transition is complete or adding the year to make it clear this refers to a past event.

Typo: The admonition block syntax appears to have an extra colon. It reads '::::info Grok Code Fast - Free Access in Roo Code', but should likely be ':::info Grok Code Fast - Free Access in Roo Code'.
