Grok 4.3 (batch)

Grok 4.3 is xAI's frontier general-purpose model available in a batch processing variant with a 1-million-token context window.

Strengths

The batch mode reduces latency for non-real-time workloads and pairs with the large context window to handle long documents and code repositories in a single request.

Best for

Processing large documents, analyzing extended code repositories, and batched inference tasks where latency is not a constraint.

Limitations

Later releases including Grok 4.5, 4.6, and 4.7 have superseded this model for general-purpose and software engineering tasks; for coding work specifically, Grok Build 0.1 is the dedicated alternative.
