ReAct and Reflection in AI

ReAct: The “Think and Do” Agent

The ReAct (Reason + Act) framework gives AI a structure for interacting with the world. It’s powerful for tasks where an AI needs to use tools, fetch data, or navigate environments. But here’s the catch: once it produces an answer, there’s no mechanism to check if it was wrong.

Reflection: The “Learn From Mistakes” Agent

Instead of stopping after one answer, a reflective agent has a feedback loop. Reflection gives AI something like metacognition — the ability to think about its own thinking. The tradeoff is that it’s slower and more expensive (more processing steps).
