by MiniMax

Released 58 days after MiniMax M2 · All MiniMax releases

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.

Uptime and availability

MiniMax M2.1 runs on a single route through the Opper gateway today, so its availability is that provider's availability.

100%route uptime, last 30 days
Single route, no failover target within this model.

Name a second model in the same request and the gateway tries it on retriable errors, so a busy hour never has to reach your users. Set up a fallback chain.

Measured over the last 30 days from each provider's official status feed via StatusGator. Refreshed hourly. See uptime for every provider Opper monitors.

Data handling per route

Each route hosting MiniMax M2.1 has its own privacy posture, residency, and GDPR terms. Postures are maintained by Opper with a last-verification timestamp.

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 — 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 a coding agent like Claude Code, Cursor or Codex 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);
