Replicate is a general-purpose model hosting platform with a huge catalog and pay-per-second billing; adult content is at best tolerated per model, never promised.

When Replicate is the better choice
Replicate is great for experimenting across many models and for SFW production. If a model you rely on there is removed or gains a safety checker, your product breaks — which is the risk 18models is built to remove.
Moving to 18models
- Get an API key and $5 of test credit (contact); one key covers every model.
- Map your calls:
POST /ent/v2/generatewithmodel,prompt, media arrays andparams, then pollGET /ent/v2/tasks/{task_id}. Field tables in the docs; Novita users have a step-by-step guide. - Run your prompt regression set on Wan 2.7, HappyHorse or Seedance 2.5 and compare unit costs on /pricing.
- Read the Content Policy — minors and real people are banned absolutely and screened; if your app respects those lines, nothing else changes.
FAQ
Is NSFW allowed on Replicate?
Replicate's terms prohibit non-consensual and illegal sexual content and reserve the right to remove models. Some community models may generate adult content, but there is no platform-level allowance you can build a business on.
Why does 'in writing' matter?
Because your payment provider, app-store reviewer or investor will ask. A published content policy that says what is allowed — and what is banned absolutely — is the difference between a tolerated workload and a supported one.
Does 18models offer the same Wan models as Replicate?
18models serves the official Wan 2.7 family (t2v, i2v, r2v, video edit) and Wan 3.0 early access, plus HappyHorse, Seedance 2.5, Qwen-Image and Z-Image — all NSFW-permitted under one policy.
