What is ReAct Prompting?

ReAct Prompting is one of the well-known prompting techniques used to interact with artificial intelligence models.

• Prompt Type: Reasoning-Based
• Definition: The AI alternates between reasoning about a step and taking an action, like searching, to solve a problem.
• Typical Use Case: Fact-finding or research tasks requiring external information and logical steps.
• Advantages: Combines reasoning and action for accurate results; effective for dynamic tasks.
• Disadvantages: Depends on reliable external sources; can be slow due to iterative process.
• Implementation Tips: Include clear instructions for reasoning and action steps, like “think then search,” to streamline the process.
• Skill Level Required: Advanced – Requires understanding of how to structure reasoning and action steps, plus access to external sources.

Examples:

1. “To find the population of Tokyo, think ‘I need the latest data,’ search for it, then report the number.”
2. “To identify the tallest mountain, think ‘I need a reliable source,’ search, and provide the answer.”
3. “To find the release date of a movie, think ‘I need to check a database,’ search, and share the result.”
