ProtoReasoning: Unlocking Cross-Domain Reasoning in LLMs Through Abstract Prototypes When we train large models to solve math problems, they spontaneously master story creation—new research reveals abstract reasoning prototypes as the key to cross-domain generalization. Abstract reasoning patterns The Bottleneck and Breakthrough in LLM Reasoning Recent advances in Long Chain-of-Thought (Long CoT) trained Large Reasoning Models (LRMs) demonstrate remarkable cross-domain generalization. For example: DeepSeek-R1 transfers skills from math/coding to STEM and creative writing Logic-RL migrates logical puzzle-solving to mathematical reasoning Yet the mechanism behind this cross-domain generalization remained mysterious until ByteDance Seed and Shanghai Jiao Tong University researchers identified shared abstract …
