DeepMMSearch-R1: Empowering Multimodal LLMs in Multimodal Web Search

Summary

The article presents DeepMMSearch-R1, a novel multimodal large language model designed to enhance web search capabilities by integrating both image and text search functionalities. This model addresses the limitations of existing retrieval-augmented generation methods by enabling dynamic query crafting and multi-turn web searches. The authors introduce a two-stage training pipeline that includes a supervised finetuning phase and an online reinforcement learning optimization, supported by a new multimodal visual question answering dataset. Extensive experiments demonstrate the model's effectiveness in knowledge-intensive benchmarks, providing insights into improving multimodal web search applications.
