## MMSearch-R1-7B

### Introduction
MMSearch-R1-7B is a search-augmented LMM trained with end-to-end reinforcement learning, equipped with the ability to invoke multimodal search tools on demand. In 2025-08, we update this model by integrating improved reasoning capabilities. Please check our [blog](https://www.lmms-lab.com/posts/mmsearch_r1_improved/).

### Model Details

- Architecture: Qwen2.5-VL-7B base model, fine-tuned with Reinforcement Learning (GRPO)
- Model type: Multimodal Large Language Model with Search-Augmentation
- Languages: English(primary), multilingual(partially)
- License: Apache license 2.0
- Paper: [MMSearch-R1: Incentivizing LMMs to Search](https://arxiv.org/abs/2506.20670)
