xAI Models

Use xAI Grok language models in Spice with an xAI API key, and grok-4.3 as the default model.

To use a language model hosted on xAI, specify xai path in the from field and the associated xai_api_key parameter. When no model is specified in the from field (i.e., from: xai), the default model is grok-4.3.

Param	Description	Default
`xai_api_key`	The xAI API key.	-
`xai_usage_tier`	xAI usage tier (0-4). Used for rate limit defaults.	-

Example:

models:
  - from: xai:grok-4.3
    name: xai
    params:
      xai_api_key: ${secrets:SPICE_GROK_API_KEY}

Refer to the xAI models documentation for more details on available models and configurations.
