MMR1-Math-v0-7B is a Large Multimodal Model specialized in mathematical tasks. Remarkably, MMR1-Math-v0-7B achieves state-of-the-art performance among open-source 7B multimodal models, competing effectively even against proprietary models with significantly larger parameter sizes—all trained using only 6k carefully curated data instances.

Key Highlights:

SOTA Performance: Sets a new state-of-the-art benchmark on math-related multimodal tasks among open-source 7B models.
Minimal Training Data: Remarkably achieves top-tier performance with just 6k high-quality samples from public training datasets.
Efficient Training with GRPO: 6 hours of RL training with 64 H100s for 15 epochs.
Public and High-Quality Data: Publicly sourced datasets, rigorously filtered and balanced across both difficulty and mathematical problem types.
Balanced Data Strategy: Uniform sampling of data based on both task difficulty (filtering out overly simple problems) and mathematical reasoning diversity.

Evaluation Results

We evaluated our model using VLMEvalKit on four mathematical reasoning benchmarks: MathVista_MINI, MathVision, LogicVista, and MathVerse_MINI.

We also include results on the MathVerse_MINI_Vision_Only_cot (MathVerse_V) subset to maintain consistency with the VLMEvalKit leaderboard. The table below compares our model's performance against various open-source and proprietary models.

Quick Start

python

Batch inference

python

            {"type": "text", "text": "What are the common elements in these pictures?"},
        ],
    }
]
messages2 = [
    {"role": "system", "content": "You are a helpful assistant."},
    {"role": "user", "content": "Who are you?"},
]
# Combine messages for batch processing
messages = [messages1, messages2]
# Preparation for batch inference
texts = [
    processor.apply_chat_template(msg, tokenize=False, add_generation_prompt=True)
    for msg in messages
