Commercial use #

Summary
Reviewed Europe consumer terms assign output rights to users to the extent allowed by law. Not a copyright or third-party clearance guarantee; API/business terms are separate.

Source review: 2026-10-21

Privacy #

Summary
API training is disabled by default; standard abuse logs can last 30 days, and Responses state has separate retention. Consumer terms permit improvement use with a training opt-out. Do not equate these regimes.
