• 2025.11.14: We have released the MiMo-VL-Miloco-7B and MiMo-VL-Miloco-7B-GGUF. Enjoy it!

Introduction

Welcome to Xiaomi MiMo-VL-Miloco — the first open-source multimodal model built to actually understand what’s happening at home!

🤗 Why you’ll love it:

• Built on MiMo-VL-7B: a rock-solid vision–language backbone with reliable video understanding and instruction-following.
• Home-savvy by design: it spots everyday activities (esports, workouts, watching TV, reading, and more) and reads common hand gestures like the V sign, thumbs-up, open palm, OK, and even the shaka hand sign.
• Base skills intact: with a mix training strategy of SFT and RL, we boost home-scene smarts while keeping the model’s generality and transferability in great shape.

🌟 Training recipe:

We use a carefully tuned two-stage pipeline to nail home-scene skills without sacrificing general abilities.

Stage 1: Supervised Fine-Tuning (SFT)

This stage focuses on boosting the model’s core capabilities in home scenarios. Even with a limited training set, we strike a good balance between sample-efficient learning and fast inference:

• Chain-of-thought supervision: we add chain of reasoning so the model learns structured knowledge about home scenarios.
• Token-budget-aware reasoning: training with “budgeted” reasoning encourages concise, straight-to-the-point answers at inference.

Stage 2: Reinforcement Learning (RL)

Building on fine-tuning, this stage introduces GRPO-based reinforcement learning to enhance the model’s overall performance:

• Efficient Training Data: we employed the Time-R1 data strategy (our work accepted at NeurIPS 2025) to build efficient training datasets across multiple domains.
• Keep-it-general: specialize for home tasks while preserving broad understanding and language generation.

In short: Xiaomi MiMo-VL-Miloco is your friendly, sharp-eyed model roommate—great at recognizing what’s going on around the house, and still ready for the wider world.

😉 Model Recomendation

Both versions of the MiMo-VL-Miloco-7B model are now open-sourced:

• MiMo-VL-Miloco-7B

  • Recommended for most users to experience and utilize.

• MiMo-VL-Miloco-7B-GGUF

  • This is the mixed-precision quantized version of MiMo-VL-Miloco-7B. It is recommended for evaluation and use in compute-constrained environments.

Performance

Evaluation of Home-Scenario Undersatnding Capabilities (F1-Score)

• MiMo-VL-Miloco-7B achieves leading performance in both gesture recognition and common household scene understanding.

Results of general capability evaluations

In household scene understanding, we prioritize video and image perception alongside the model’s reasoning ability.

• Across three video benchmarks (Video-MME, Video-MMMU, Charades-STA), the base model shows clear improvements.
• On MMMU-Pro, a general-capabilities benchmark, the base model also saw significant improvements (10+%).
• Surprisingly, as video and image understanding improved, we observed corresponding gains on the text-only task MMLU-Pro.
• We see a modest performance dip on tasks such as document understanding, OCR, and mathematics; this is in line with expectations and does not affect the model’s intended use cases.

Deployment

Thinking Control

We follow the same approach as MiMo-VL. Users can control the thinking mode by appending /no_think to queries:

• Thinking mode (default):

  "Explain the relationships between the objects in the image and infer the likely next action."
  

• Non-thinking mode:

  "Transcribe the handwritten note exactly as shown. /no_think"
  

Gradio Demo

• Installation

pip install -r requirements.txt

• Deployment

cd demo
CKPT_PATH="checkpoint_path" python app.py

Mode Switching

In the interface, you can click Smart Home mode to switch to the home scenario mode.
