How do frontier LLM systems perform self-evaluation and self-correction?

Self-evaluation systems allow LLMs to critique, verify, and revise their own outputs before delivering final responses.

One of the major limitations of early LLMs was their inability to reliably recognize mistakes.

Modern systems increasingly incorporate self-evaluation pipelines where models:

Self-correction architectures typically involve:

Producing an initial response.

Evaluating correctness, completeness, and safety.

Generating revised alternatives.

Checking against rules, tools, or external data.
