Prompt Engineering Lab

See exactly how prompt strategy affects LLM output — zero-shot vs few-shot vs chain-of-thought vs ReAct.

Prompt Strategy

⚡ Zero-Shot

Direct question with no examples — relies purely on model knowledge.

📖 Few-Shot

Provide 2–3 examples before the question to guide the model's format and reasoning style.

🧠 Chain-of-Thought

Instruct the model to think step-by-step before answering — improves reasoning accuracy.

🔄 ReAct

Reason + Act pattern: the model alternates between Thought, Action, and Observation before concluding.
