API: OpenAI-compatible, base URL https://api.aimlapi.com/v1

MiniMax M3 is the flagship reasoning model from MiniMax, built for agentic workflows, long-document processing, coding tasks, and complex multi-step reasoning at scale. It supports a context window of up to 1 million tokens, one of the largest available in production, and introduces multimodal input support alongside a reasoning architecture designed for frontier-tier performance.

Where previous MiniMax models excelled at conversational tasks and general instruction-following, M3 was purpose-built for environments where context depth, tool-use reliability, and sustained reasoning across long sessions actually matter. It's the first MiniMax model explicitly positioned at the agentic frontier.

Context window: 1,000,000 tokens
Multimodal: Yes (text + image input)
Tool calling: OpenAI-compatible function calling

Use cases

MiniMax M3 is documented as suited to coding tasks, including bug fixing, frontend/backend development, performance optimization, and long-horizon coding work. It is also suited to agentic workflows, including autonomous task decomposition, tool invocation, multi-step reasoning, and automated workflows. It is documented for multimodal use cases such as long-form video understanding, image and video input, and computer use on desktop applications. It is also described as suitable for office-style workflows and design or creative workflows.
