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)
| Level | When to use it, per xAI | AA index | Tokens/s |
|---|---|---|---|
| low | No per-level advice published | – | – |
| medium | No per-level advice published | – | – |
| high default | No per-level advice published | – | – |
| xhigh | No per-level advice published | – | – |
Our rule of thumb: Simple or speed-critical work: low. Standard work: the lab's default. Complex work: high. Use xhigh or max only when your own tests show a gain, as OpenAI and Anthropic both advise. developers.openai.com (opens in a new tab)platform.claude.com (opens in a new tab)

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.
Same type, closest on quality index and blended price. A similarity, not a ranking.
