An advanced prompting technique that combines Reasoning and Acting: the model alternates between thinking step by step and executing concrete actions (such as calling a tool or API), observing the result before continuing to reason.
In GENAI-L (Domain 3) it is presented as an advanced technique alongside chain-of-thought. It is the conceptual basis for how AI agents work: the model decides which tool to use, invokes it, observes the result, and decides the next step.
ReAct prompting is a concept that can show up on the exam. Check the full guide to see it in context.
