MiniMax M2.1

by MiniMax

MiniMax M2.1 is a 229-billion-parameter Mixture-of-Experts model released in December 2025 under a modified MIT license. It was tuned for robustness in coding, tool use, instruction following, and long-horizon planning across agentic workflows. The model shows strong multilingual programming, scoring 72.5 on SWE-bench Multilingual and 74.0 on SWE-bench Verified, with 88.0 on MMLU-Pro and 83.0 on GPQA-D. It reaches an average VIBE score of 88.6 (with 91.5 on VIBE-Web and 89.7 on VIBE-Android), reflecting robust full-stack and native mobile development capability. The sparse architecture supports faster inference and responsive agentic loops, and MiniMax positions M2.1 as matching or approaching leading proprietary coding models on real-world software engineering tasks.

Get started

Call MiniMax M2.1 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: "novita/minimax-m2.1",
messages: [{ role: "user", content: "Hello" }],
});
console.log(completion.choices[0].message.content);
