SpaceXAI: Grok 4.7

SpaceXAI: Grok 4.7 is a paid model from x-ai that accepts text, image, and file inputs. It offers a 500,000-token context window and can return up to 450,000 tokens in a single completion, which suits long documents, large codebases, or lengthy generated output. It supports tool use and reasoning. The listing does not document structured output support or whether the weights are open, so confirm both before relying on them. At $2 per million input tokens and $6 per million output tokens, it is a reasonable shortlist candidate for teams that need very long context and large outputs with tools and reasoning, and that are willing to pay for it. Its blended benchmark score of 79.2 rests on a single independent benchmark, so its standing is thinly evidenced. Treat that number as a starting point, and test the model on your own workloads before committing.
