Grok 4.3 (batch)

A reasoning model from xAI that processes text and image inputs, with a 1-million-token context window.

Strengths

Handles instruction-following tasks and agentic workflows with strong factual accuracy across multimodal inputs.

Best for

Applications requiring extended context for reasoning over long documents, conversations, or instruction chains where image understanding is also needed.

Limitations

Superseded by Grok 4.5 and Grok 4.6 for frontier reasoning capabilities; Grok Build 0.1 is more efficient for code-specific tasks.
