Luma AI uses a multi-layered moderation system that combines AI filters with human oversight to screen prompts and generated videos on Dream Machine and the Dream Machine API for policy violations.

According to Luma's own API documentation, the moderation system applies to all video generations on the platform and via the API, covering categories such as harmful content, graphic violence, and sexually explicit material. API customers can customize the moderation settings to match their market and user base. Appeals for incorrectly flagged content can be submitted to Luma's moderation team via email. The system is described as combining automated AI filters with human review.
