Second Thought: Reasoning in Parallel as LLM Agents Act and Observe

Researchers have introduced a framework called Second Thought that allows LLM agents to perform reasoning tasks in parallel with environment actions. By moving beyond the traditional sequential ReAct model, this method prevents system idle time and enables continuous deliberation while the agent waits for external feedback. This improvement aims to increase the efficiency and responsiveness of AI agents tasked with complex, multi-step operations.
