MiMo-V2.6-Flash-RL

Handles text, image, video and audio input in one model, with a 1M-token context for long repositories and agent runs. An open 311B mixture-of-experts model from XiaomiMiMo.

About

What it is: MiMo-V2.6-Flash-RL is a text generation model from XiaomiMiMo. It is one checkpoint in the MiMo-V2.6 series that balances efficiency, and its training relied on reinforcement learning. It is a sparse mixture-of-experts model with 309B total and 15B activated parameters, and it takes text, images, video and audio.

Who it suits: Developers and research teams who want a large open model for coding, agent work and long documents, and who have the hardware to host it.

Industry | Who uses it | How they use it | Example
Software | Developers | Feed a long repository or tool trace into one request | Review a codebase in a single context
AI research | Researchers | Study reinforcement learning at scale on an open checkpoint | Compare it with other open models
Agents | Agent builders | Run multi-session agent tasks that need a long memory | A coding agent that works across sessions
Media | Analysts | Ask questions about video or audio together with text | Summarize a recorded meeting

If you only need a small model on a laptop, you can skip it, since the weights run to about 311 GB.

Where to use it:

• Windows, macOS or Linux with Python, for downloading the files
• Python programs that use the transformers library
• Xiaomi's own API platform, Studio and Desktop app, which the card lists

Use case | Who | What they get back
Long-context coding | Developers | Answers drawn from up to 1M tokens of code and traces
Multimodal questions | Analysts | Replies based on images, video or audio plus text
Agent runs | Agent builders | A model trained on coding, agent, visual and cybersecurity tasks

How to set it up:

• Python, to run the Hugging Face download tool
• About 311 GB of disk space for the weights
• Server-class hardware that can host a 311B model

1. Install the Hugging Face hub tools with pip.
2. Download the model files with the hf command.
3. Follow the model card for how to run it.

pip install -U huggingface_hub
hf download XiaomiMiMo/MiMo-V2.6-Flash-RL

How to use it: Once the model is loaded in a serving setup, you send it text, and optionally images, video or audio, and read the reply. The card says it supports a 1M-token context, so long inputs fit in one request.

Example: You paste a large repository and ask "Which files handle user sign-in, and what would break if I rename the session table". The model reads the whole input in one pass and answers with the files and the likely effects.

For newcomers and experts: This is a huge model, so the first small step is to read its model card and try Xiaomi's hosted options before planning your own server. Downloading the weights alone takes about 311 GB.

Training mixed coding, general agent, visual and cybersecurity tasks in a single reinforcement learning run. It used asynchronous GRPO, with 1,568 prompts and 16 rollouts per step. Groupwise grading ranks passing solutions to favor shorter paths. A 5-layer multi-token prediction block works as a speculative decoder.

Text, image, video or audio goes in
MoE routes to 15B active parameters
Model reads up to 1M tokens
Answer comes back

Good to know:

• License: MIT
• Cost to run: none named, but the weights are about 311 GB and need strong hardware
• Data it reaches: downloads files from Hugging Face, then runs where you host it
• Not for: small machines, since the model is a 311B mixture-of-experts design

Get the model

Download its files with Hugging Face's command line:

pip install -U huggingface_hub
hf download XiaomiMiMo/MiMo-V2.6-Flash-RL

Then follow the usage in its model card. Nothing in this kit runs by itself.
