MiniMax M3

by MiniMax

MiniMax M3 is an open-weight multimodal model released June 2026, combining frontier coding performance with a 1M-token context window and native image and video understanding. It is positioned as the first open-weight model to bring frontier coding, million-token context, and native multimodality together in one architecture. The model is built around roughly 428 billion parameters with about 23 billion activated per token, using MiniMax Sparse Attention to cut per-token compute at 1M-token scale to roughly one-twentieth that of the previous generation, with more than 9 times faster prefill and more than 15 times faster decoding versus M2. It undergoes mixed-modality training from the start for deeper fusion across text, image, and video. M3 targets long-horizon agentic and coding tasks, scoring 59% on SWE-Bench Pro and 83.5 on BrowseComp. It supports multiple reasoning modes through the thinking parameter and is designed for tool use, computer use, and document and chart parsing across extended contexts.

Get started

Call MiniMax M3 through the Opper gateway with one API key. Let your coding agent set it up, or call it directly β€” Opper is drop-in compatible with the OpenAI, Anthropic, and Google AI SDKs.

Set it up with your agent

Copy this and paste it into your coding agent β€” Claude Code, Cursor, Codex, and more β€” and it'll wire up Opper for you.

Or call it directly

import OpenAI from "openai";
const client = new OpenAI({
apiKey: process.env.OPPER_API_KEY,
baseURL: "https://api.opper.ai/v3/compat",
});
const completion = await client.chat.completions.create({
model: "minimax/m3",
messages: [{ role: "user", content: "Hello" }],
});
console.log(completion.choices[0].message.content);
