How much detail would you like?
Practical
Helps you to check the desired behavior and technical performance together.
Example scenario: After an adjustment, a team compares both unwanted answers and the quality of permitted specialist answers.
After adjustments, compare technical tasks and behavioral requirements with the same test setup.
At a glance
- Core
- Alignment Tax refers to possible performance losses caused by alignment measures compared to a comparative version. The effect depends on model, procedure, task and measurement. It is neither an inevitable consequence of alignment nor a monetary levy.
- Use
- 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.
- 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.
