SpaceXAI: Grok 4.3 (batch)

SpaceXAI: Grok 4.3 (batch) is a model from x-ai that accepts text, image, and file inputs. It offers a 1,000,000-token context window and allows up to 900,000 completion tokens, so it can take in large documents and return long outputs in a single request. It supports tool use and reasoning. The listing does not specify structured output support or whether the weights are open, so confirm both before relying on them. At $1.00 per million input tokens and $2.00 per million output tokens, this is a paid model with low per-token rates. That makes it worth shortlisting for high-volume or long-context jobs where cost per token matters. The batch label suggests it is meant for bulk processing, though the facts here do not describe how batching works. It has no independent benchmark coverage yet, so its quality is unproven. Test it on your own tasks before committing.
