The Grok 4.20 and Grok 4.20 Multi-Agent models are no longer available in the Windsurf model selector. These were previously available and are essential for high-reasoning and collaborative agent tasks. Please restore access to these xAI models.
Steps to Reproduce:
Open Windsurf on macOS.
Open the Cascade panel.
Click the model selection dropdown.
Search for grok-4.20 or grok-4.20-multi-agent.
Observe that these models are missing from the list.
Expected Behavior:
The flagship Grok 4.20 series models should be selectable for use within the Cascade chat and coding workflows.
Suggested Technical Fix:
Please verify if the integration needs to be updated to the latest stable xAI model IDs (e.g., grok-4.20-reasoning) or if the multi-agent variant requires the newer /v1/responses API endpoint.
