The Power of the React Loop: Zero-to-Production Guide
Introduction Most LLM systems are fundamentally reactive: you ask a question, they generate an answer, and that’s it. If the first answer is wrong, there’s no self-correction. If the task requires multiple steps, there’s no iteration. If results don’t meet expectations, there’s no refinement. The React Loop changes this paradigm entirely. It transforms a static, one-shot LLM system into a dynamic, iterative agent that can: Sense its environment and gather context Reason about what actions to take Act by executing tools and generating responses Observe the results of its actions Evaluate whether it succeeded or needs to try again Learn from outcomes to improve future iterations The core insight: ...
