About Grok 4.3 Vision

Large-context vision model from X.ai

Grok 4.3 Vision is a vision model developed by X.ai, the AI division associated with xAI. It carries the internal model identifier grok-4.3 and is available as a first-party offering, meaning it is served directly by X.ai rather than through a third-party provider. The model supports a context window of 2,000,000 tokens, which also matches its maximum response size, making it suited for tasks that involve very long documents or large volumes of input data.

Grok 4.3 Vision is designed to handle vision-related tasks, enabling it to process and reason about image content alongside text. Its exceptionally large context window makes it particularly applicable to use cases that require analyzing extensive materials in a single pass, such as document-heavy workflows or multi-image analysis. The model was released in March 2026 and is currently available on MindStudio without requiring users to manage their own API keys.
