xAI: Grok Latest
xAI: Grok Latest accepts text, image, and file inputs and offers a 500,000-token context window with up to 450,000 completion tokens. It supports tool calling and reasoning, which fits agent workflows and multi-step tasks. Structured output support is not listed, so teams that depend on strict schema responses should test that behavior before committing. Pricing is $2.00 per million input tokens and $6.00 per million output tokens. The benchmark evidence is thin: a blended score of 5.8 drawn from a single independent benchmark, with an AI Index reading of 11.4. One data point is not enough to rank it confidently against alternatives, so its quality remains largely unproven. Shortlist it if long documents, very long generations, or mixed image and file inputs are central to your work, and run your own evaluations before choosing it on quality.
