PerceptRL framework boosts MLLM visual perception with agentic RL

Researchers have developed PerceptRL, a novel framework designed to enhance the visual perception capabilities of multimodal large language models (MLLMs). This system addresses limitations in fine-grained visual perception by using a multi-agent pipeline to extract verified errors from image captions and convert them into question-answering pairs with rule-based rewards. PerceptRL also incorporates multi-turn inspection with visual tools to tackle complex perceptual issues and corrects spatial operations to improve accuracy in tool-use scenarios. In evaluations across seven benchmarks, PerceptRL achieved a 71.6% average accuracy, significantly outperforming base models and leading frontier vision-language models. AI

IMPACT Enhances MLLM visual perception, potentially improving performance in tasks requiring detailed image understanding and tool use.

    PerceptRL: Making Visual Perception Rewardable in MLLMs from Answers to Interactions

    arXiv:2610.37471v1 Announce Type: cross Abstract: Fine-grained visual perception remains a bottleneck during post-training of multimodal large language models (MLLMs), as perceptual errors can constrain gains from reasoning-focused optimization. Although image-caption pre-trainin…
