AI agents use evaluator-optimizer loops for refined output generation

The evaluator-optimizer pattern involves one AI agent generating output while another evaluates it and provides feedback in a loop, aiming to refine the response. Anthropic refers to this as the evaluator-optimizer, while Google frames it as a generator-critic loop for correctness and an iterative refinement loop for quality. Both approaches require a clear exit condition to prevent excessive costs and system hangs, with a maximum iteration count being a crucial safety measure. AI

IMPACT This pattern can improve the quality and correctness of AI-generated outputs by introducing iterative refinement and critique.

    Evaluator-Optimizer: Generate, Critique, and Refine in a Loop

    <p><strong>Short version:</strong> The evaluator-optimizer pattern has one agent generate output while another evaluates it and gives feedback, in a loop. Anthropic calls it evaluator-optimizer. Google splits the same idea into a generator-critic loop for correctness and an itera…
