Iterative self-improvement framework for language models through feedback and refinement

Core Idea: SELF-REFINE is a framework that enables language models to improve their own outputs through a continuous cycle of generation, self-evaluation, and refinement, without requiring external feedback or additional training.

Key Elements

Framework Components

• Initial Generator: The LLM produces a first draft response to a given prompt
• Self-Feedback Generator: The same LLM evaluates its own output and provides specific feedback
• Output Refiner: The LLM revises its initial output based on the self-generated feedback
• Iterative Process: The cycle can repeat multiple times until satisfactory quality is achieved

Self-Refinement Cycle

1. Initial Generation: Model produces an initial response to the input prompt
2. Self-Critique: Model analyzes its own output for errors, inconsistencies, or areas for improvement
3. Feedback Formulation: Model articulates specific, actionable feedback about the output
4. Refined Generation: Model creates an improved version incorporating the feedback
5. Iteration: Steps 2-4 can repeat until convergence or quality threshold is met

Implementation Methods

• Role-Playing: The model adopts different personas for generation and critique
• Structured Prompting: Using standardized templates for each phase of the process
• Quality Criteria: Explicit definition of evaluation dimensions (correctness, completeness, etc.)
• Halting Mechanism: Determining when the refinement process should terminate

Key Advantages

• Independence: Works without human feedback or external evaluators
• Versatility: Applicable across diverse tasks and domains
• Efficiency: Uses the same model for all three roles (generation, feedback, refinement)
• Scalability: Can be applied to any LLM without architectural modifications
• Continuous Improvement: Enables progressive enhancement of outputs

Differences from Similar Techniques

• vs. Reflexion: Focuses on improving specific outputs rather than agent behavior
• vs. Constitutional AI: Doesn't require separate training or reinforcement learning
• vs. Human Feedback: Operates without external input or evaluation
• vs. Simple Revision: Includes explicit feedback generation as a separate step

Application Domains

• Content Creation: Writing, summarization, creative text generation
• Programming: Code generation, documentation, bug fixing
• Problem Solving: Mathematical solutions, logical puzzles
• Information Synthesis: Research summaries, literature reviews
• Integration with Agents: Component within broader reasoning frameworks like ReAct
