    Why it matters in practice

    Helps you to check the desired behavior and technical performance together.

    Example

    Example scenario: After an adjustment, a team compares both unwanted answers and the quality of permitted specialist answers.

    Pitfalls and limits

    • Count any rejection as a drop in performance; assume universal percentages; use unsuitable comparison models.

    Origin & history

    Bai and co-author:innen investigated 2022 RLHF for the targeting of helpful and harmless assistants. The work reports improvements on almost all NLP evaluations considered; performance losses are therefore not a common obligatory consequence.

    Use in mid-sized companies

    • After adjustments, compare technical tasks and behavioral requirements with the same test setup.
