What is allowed
NSFW output is permitted under the 18models Content Policy: fictional adult content, including explicit sexual content, is allowed; content involving minors (in any style) or real, identifiable people is prohibited absolutely and screened on both input and output. Upstream providers apply their own checks in addition to ours — a task rejected upstream fails and is refunded automatically.
- Reference images of real, identifiable people are prohibited for NSFW generation (Content Policy §2) — use generated or licensed fictional characters as references.
- Reference-to-video is capped at 10 seconds when a video reference is included; video edit keeps the input duration up to 10 seconds.
