SpaceXAI: Grok 4.7

SpaceXAI: Grok 4.7 is a model from x-ai that accepts text, image, and file inputs. It offers a 500,000-token context window and can produce up to 450,000 tokens in a single completion, which suits long documents, large codebases, or extended multi-part outputs. It supports tool use and reasoning. Its listing does not specify structured output support or open-weight availability, so teams that depend on either should confirm before committing. Pricing is $2.00 per million input tokens and $6.00 per million output tokens, and there is no free tier. The model has no independent benchmark coverage yet, so its quality relative to alternatives is unproven. It belongs on a shortlist for buyers who need very long context, large outputs, and multimodal file handling with tools and reasoning. Those buyers should run their own evaluations before adopting it, because published scores are not available to guide the choice.
