Researchers have developed a new post-training reinforcement learning method called TRAAC (Think Right with Adaptive, Attentive Compression) to address under- and overthinking in large language models. TRAAC uses self-attention mechanisms to identify and prune redundant reasoning steps, while also learning to allocate a reasoning budget based on task difficulty. When applied to the Qwen3-4B model, TRAAC achieved significant accuracy gains across various tasks, including AIME, AMC, GPQA-D, and BBEH, while simultaneously reducing the length of reasoning steps.
