What stands out

What its maker marketed at launch, and what people found later, each with its source.

  • Four-level reasoning effort incl. xhigh

    Configurable reasoning effort low / medium / high / xhigh (default high) on one model id.

    Source: docs.x.ai

  • 500K context at unchanged price

    500K-token context with text+image input; launched at the same $2/$6 price as Grok 4.6 while claiming notable gains.

    Source: docs.aws.amazon.com

  • Mixed independent benchmark results

    Found after launch

    Early third-party evals showed a more mixed picture than xAI’s claims, still behind top Claude/GPT-6 models on several tasks.
