AI Disclosure

All images produced by Thumbly are generated by an AI model. They are not photographs, do not depict real events, and may contain artifacts or inaccuracies.

Model and providers

We use OpenAI's image generation model and moderation API. Inputs (prompts and reference images) are sent to OpenAI for processing. OpenAI does not use API content to train its models by default.

Content policy

Every prompt is screened by OpenAI's moderation API and our own blocklist before a credit is spent. We block sexual, violent, hateful, and impersonation content. Users may not generate likenesses of public figures without consent.

Disclosure on YouTube

YouTube's rules require creators to disclose "altered or synthetic content" that could mislead viewers. Most thumbnails do not require disclosure, but you should review YouTube's guidance for your specific video.
