string

Use grok-4.6 through a supported SpaceXAI or partner model surface.

input

object

Text or supported image input sent through the Responses API or equivalent supported client.

reasoning_effort

string

Choose low, medium, high, or xhigh; high is the documented default.

tools

array

Optional function, web search, X search, or code-execution tools supported by the active surface.
