    Definition

    RLAIF uses AI evaluations as a basis for reinforcement learning.

    A training approach in which an AI system generates evaluations, critiques, or preference labels from which a reward model or other feedback signal is derived for subsequent optimization with reinforcement learning.

    Simply explained

    An AI evaluator assesses responses; feedback is generated from this, with which a model continues learning.

    Why it matters in practice

    The term helps to select, develop, evaluate AI systems in a well-founded manner and realistically assess their technical risks.

    Example from business

    An AI critic evaluates response pairs based on human-defined principles; from this, a reward signal is generated for further optimization of a model strategy.

    Limits and pitfalls

    • Considering AI feedback as independent or error-free, equating RLAIF with any use of synthetic preferences or fully autonomous alignment, or removing human guidelines, audits, and oversight.

    Origin & history

    RLAIF became known in works on Constitutional AI and scalable alignment from 2022 onwards.

    Use in mid-sized companies

    • Possible application: An AI critic evaluates response pairs based on human-defined principles; from this, a reward signal is generated for further optimization of a model strategy.
