Second Thought: Reasoning in Parallel as LLM Agents Act and Observe
The paper tests whether an agent can keep reasoning while its action is out in the environment.
Second Thought forks four auxiliary reasoning branches after each Thought phase, runs them alongside the main ReAct loop, then merges them when the observation returns. The authors report lower average turn counts across all nine model-benchmark pairs they tested. Main-thread decoding fell in six pairs, by up to 43%, with Pass@1 mostly unchanged and two significant gains. HF Daily Papers' note
