arXiv:2601.00215v2 Announce Type: replace-cross Abstract: Reinforcement learning with verifiable rewards has driven major gains in LLM reasoning, and it is intuitive to assume this recipe will transfer well to multimodal models. However, multimodal models do two things: first, perceive what is in an image, then reason about what it implies. Because these stages are graded jointly, it is hard to tell how much room reasoning alone has to grow. We study this on algorithmic visual puzzles, where both components are necessary and show that perception, not reasoning, is the binding constraint. Repla
This research is emerging as multimodal AI models become more prevalent, and distinguishing their perceptual limitations from reasoning capabilities is crucial for future development and deployment.
Understanding the bottlenecks in multimodal LLMs, specifically identifying perception as the current limiting factor, allows for more targeted research and development efforts to improve their performance and applicability.
The focus of multimodal AI development and evaluation shifts towards enhancing perceptual capabilities rather than solely concentrating on advanced reasoning architectures.
