The Agentic Loop and the ReAct Pattern
About this video
The agentic loop (reason, act, observe) in motion.
The ReAct pattern (Reason + Act) organizes an agent as a repeating three-step loop: reason about what to do, take an action with a tool, and observe the result. Introduced by Yao and colleagues in 2022, it interleaves reasoning and acting so the model can plan, consult external sources, and fix its own mistakes as it goes.
Video transcript
- 0:01 An agent does not answer in one shot.
- 0:03 It plans the next step, calls a tool and reads the result.
- 0:07 It repeats the loop until the goal is met, then answers.
