Overview
What is MiniMax M3 AI
MiniMax M3 is an open-weight frontier model built for coding, agentic tool use, and long-context work. It accepts native text, image, and video input, and its MSA architecture cuts per-token compute at 1M context to about 1/20 of the previous generation.
Open-weight frontier model
Released with open weights, model ID minimax/minimax-m3, focused on coding and agentic tasks.
MSA architecture, 1M context
Multi-Sparse-Attention keeps 1M-token context affordable — about 1/20 the per-token compute of the prior generation.
Native multimodal input
Accepts text, image, and video input with text output.

MiniMax M3 FAQ
Common questions about M-Chat, MiniMax M3, Thinking, web search, and local validation.
What is M-Chat?
M-Chat is an independent web chat and research site for MiniMax M3. It is not MiniMax official infrastructure.
Which model does the chat use?
The chat backend uses MiniMax M3, model ID minimax/minimax-m3.
Does MiniMax M3 support multimodal input?
MiniMax M3 is described as supporting text, image, and video inputs with text output. M-Chat is validated for text chat.
What does Thinking do?
Thinking enables extended reasoning for prompts that need deeper analysis.
How does web search work?
The server calls Tavily search and provides the search result context to MiniMax M3 before the answer is generated.
Is MiniMax M3 free to use?
MiniMax M3 is released as an open-weight model, and M-Chat gives every signed-in user 10 free credits to try it. Beyond that, access is paid: OpenRouter and the official MiniMax API bill per token, and M-Chat sells credit plans.
How much does MiniMax M3 cost?
On OpenRouter, MiniMax M3 lists at $0.30 per 1M input tokens and $1.20 per 1M output tokens during its launch discount. The official MiniMax API is tiered by input length, with higher rates above 512K tokens. Verify live pricing before budgeting.
Is MiniMax M3 open source?
MiniMax M3 ships as an open-weight model you can download and self-host, but the release stops short of a full open-source license. Check MiniMax's terms before building a commercial product on the weights.
Is MiniMax M3 good for coding?
MiniMax M3 targets coding and agentic work, scoring 59.0% on SWE-Bench Pro and 66.0% on Terminal-Bench 2.1 in MiniMax's release. It narrowly leads the open-access group on SWE-Bench Pro, though closed models like Claude Opus 4.8 score higher.
How does MiniMax M3 compare to GPT-5.5 and Claude Opus 4.8?
MiniMax reports M3 just ahead of GPT-5.5 on SWE-Bench Pro and stronger on BrowseComp. Claude Opus 4.8 leads on raw coding (about 69.2% on SWE-Bench Pro) but costs far more. M3's pitch is near-frontier quality at a fraction of the price.
What is MiniMax M3's context window?
MiniMax M3 has a 1M-token context window, larger than many peers such as Kimi K2.6 at 256K. That makes it practical for full-repository analysis, long transcripts, and tool-heavy agent sessions inside a single prompt.
How do I use the MiniMax M3 API?
MiniMax M3 uses the model ID minimax/minimax-m3. M-Chat routes chat through OpenRouter's unified API, so you can reach the same model with an OpenRouter key and that model ID.
