MiMo V2.5 Pro

by Xiaomi

Released 35 days after MiMo-V2-Pro · All Xiaomi releases

MiMo V2.5 Pro is Xiaomi's flagship text reasoning model optimized for the agent era, built on 1.02 trillion parameters with 42 billion active per token. Released in April 2026, it brings notable gains over its predecessor in general agentic capability, complex software engineering, and long horizon task completion. The model sustains long trajectories spanning hundreds to thousands of tool calls while holding coherence across its full 1 million token context window. Training used a three phase post-training recipe: supervised fine-tuning on curated data, domain specialized reinforcement learning, and multi-teacher on-policy distillation that merges specialist strengths across coding, reasoning, and tool use. Its hybrid attention architecture interleaves sliding window and global attention at a 6:1 ratio, with three lightweight Multi-Token Prediction layers that roughly triple output throughput at inference. MiMo V2.5 Pro reaches frontier level performance while spending roughly 40 to 60 percent fewer tokens than comparable models on benchmark trajectories, shown through tasks like building a Rust compiler and a full featured desktop video editor running to thousands of lines of code. It is open-sourced under the MIT license on Hugging Face, allowing commercial deployment, continued training, and unrestricted fine-tuning.

Get started

Call MiMo V2.5 Pro 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: "deepinfra/XiaomiMiMo/MiMo-V2.5-Pro",
messages: [{ role: "user", content: "Hello" }],
});
console.log(completion.choices[0].message.content);
