WaveSpeed is a large multi-model inference platform (1,000+ models, one key) that added a Spicy collection for high-volume adult video; policy-wise it neither promises nor forbids legal adult output.

When WaveSpeed is the better choice
If you already run SFW workloads on WaveSpeed and only need occasional adult image-to-video, staying on one platform is convenient. If adult output is your product — and someone will ask you for the policy that permits it — you need it in writing.
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.
