The company describes it as an open-weight, natively multimodal model for reasoning across text and images. Gateway users can access it with one AI Gateway API key, without creating a separate Mistral account. The model identifier is mistral/mistral-large-4.
Vercel lists support through the AI SDK, OpenAI-compatible Chat Completions API, Responses API, and Anthropic Messages API. It also says developers can select the model in a coding agent connected to AI Gateway, or configure one with npx vercel ai-gateway setup. The announcement documents availability and integration routes; it does not establish pricing, benchmark results, or comparative model quality.
