Aurora's content policy
Aurora has fewer content restrictions than image generators from OpenAI, Google, or Meta. This means greater creative freedom for users, but it has also drawn criticism for potential misuse. xAI positions this as respecting user autonomy, while critics argue it requires stronger guardrails.
