Reasoning levels
Which level to choose
xAI names these settings reasoning effort. Price per token is the same at every level. Higher levels usually use more output tokens. docs.x.ai (opens in a new tab)
Smaller context (500K) than most 2026 frontier models
Higher rates above 200K tokens
Tools and MCP connectors that fit
xAI API: xAI API only: remote MCP in the Responses API, the native SDK and the Speech to Speech API. Streaming HTTP and SSE. Not the Grok app, Grok Bot or Grok Build. docs.x.ai (opens in a new tab). These official remote MCP servers fit that rule. We have not tested each server with this model. A server that publishes a client list is left out when this lab is not on it.
