Reflexion embodies metacognitive refinement, where the model generates an initial output, then adopts a critical lens to evaluate its strengths, weaknesses, coherence, and alignment with the query. Based on this introspection—scoring aspects like clarity, completeness, or creativity—it iterates revisions, incorporating improvements until convergence on an optimal version. This closed-loop polishing is akin to an author's multiple drafts, yielding sophisticated results with minimal external input, particularly suited to creative writing, code optimization, or analytical reports.
Examples
User Prompt: Refine a persuasive essay on remote work using Reflexion. AI Response: Draft 1: Benefits listed. Reflect: Lacks counterarguments. Refine: Added rebuttals to productivity concerns with data; Strengthened conclusion.
User Prompt: Optimize SQL query using Reflexion. AI Response: Initial: Basic SELECT. Reflect: Inefficient joins. Refine: Added indexes hint, reduced to subquery; Performance: 50% faster simulated.
User Prompt: Polish a product description using Reflexion. AI Response: Draft: Features bullet. Reflect: Too dry. Refine: Wove in storytelling, sensory language; Engagement score up.
User Prompt: Self-edit a poem using Reflexion. AI Response: Version 1: Raw lines. Reflect: Rhythm inconsistent. Refine: Meter adjusted, metaphors deepened for emotional impact.
