## [SpaceXAI: Grok 4.3 (batch)](https://ailoot.ai/models/en/x-ai-grok-4-3-u003a-batch/)

Grok 4.3 is a text-and-image model for instruction-driven work, reasoning and tool-connected tasks, with a 1,000,000-token context. It provides function calling, structured output and selectable reasoning effort in the producer’s documented configuration.

About the model

This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.

Grok 4.3 is the producer’s general-purpose model emphasizing instruction following and tool use. Its model card accepts text and images, generates text and specifies a 1,000,000-token context window. The listed capabilities include function calling, structured outputs and configurable reasoning, with batch processing supported in the manufacturer’s service.

The current detailed model specification lists none, low, medium, high and xhigh reasoning effort, with low as the default. None skips the reasoning stage; the other choices allocate thinking before the answer. These are settings of the exact producer model card, distinct from the effort lists and defaults of later Grok releases.

For long-document analysis, provide the relevant material and define the sections or findings the answer should return. The context can hold a large working set, but the task still benefits from priorities and an explicit deliverable. Ask for the conclusion, the supporting passage and any unresolved condition instead of treating a long context as a substitute for a clear question.

For visual material, identify the object, chart feature or page detail to inspect and explain how it relates to the written task. A useful result ties the observation to the question. If a conclusion also depends on external information, provide that evidence separately so the model can distinguish what the image shows from what another source establishes.

In a function-based workflow, the model generates a proposed call from the tool definitions. The application executes the function and returns the result. Keep the function’s inputs, the returned observation and the next model step connected. For a code or data task, request a result that states what was proposed and what the application actually observed.

Structured output can turn a document extraction or analytical report into defined fields. The producer’s schema support covers common data types and bounded constraints, while some advanced constraints depend on model behavior. Give each field a clear meaning and validate the result against the application’s needs. A schema-shaped result still needs evidence for its content; a proposed action still needs execution by the surrounding workflow.
