SpaceXAI: Grok 4.6 (batch)

SpaceXAI: Grok 4.6 (batch) is a paid model from x-ai that accepts text, image, and file inputs. It offers a 500,000-token context window and allows up to 450,000 completion tokens, so a single request can carry long documents and return very long outputs. It supports tool calling and reasoning. Structured output support is not listed, so teams that need schema-conformant responses should verify this before committing. Pricing is $1.6 per million input tokens and $4.8 per million output tokens. That makes it worth shortlisting for buyers who need long context, multimodal file handling, and tool use, particularly for workloads that generate large outputs, where the output rate matters most. The gap is evidence: it has no independent benchmark coverage yet, so its quality relative to alternatives is unproven. Treat it as a candidate for pilot testing on your own tasks rather than a pick based on published scores.
