What is Insight-V
Insight-V is a multimodal model jointly launched by researchers from Nanyang Technological University, Tencent, and Tsinghua University, capable of enhancing the long-chain visual reasoning abilities of multimodal large language models. Based on a scalable data generation pipeline, it produces high-quality reasoning data, adopts a multi-agent system to decompose visual reasoning tasks into two steps: reasoning and summarization, and combines a two-stage training process to significantly improve the model's performance on visual reasoning benchmarks. The design of Insight-V includes progressive data generation, multi-granularity evaluation, and an iterative DPO algorithm, enabling the system to demonstrate outstanding performance in complex visual reasoning tasks.

Technical Principles of Insight-V
- Progressive Long-Chain Reasoning Data Generation: Based on powerful multimodal models, it collects single-step reasoning results and generates the next reasoning action based on historical reasoning results.
- Multi-Granularity Evaluation: It uses ground-truth answers to filter reasoning data, excluding data with incorrect final answers. A reasoning step scoring model scores the quality of the reasoning data and divides the data into subsets of different quality levels.
- Model Design: Specifically generating detailed, step-by-step reasoning processes. Adapting to inaccuracies in the reasoning path, selectively incorporating or ignoring certain elements.
- Training Strategy: Supervised fine-tuning of the two agents to cultivate step-by-step reasoning and summarization abilities. Based on multi-round DPO training and sampling, simulating an online environment to improve model performance.
