Novita is a broad model aggregator (Wan, Qwen, Z-Image and hundreds more) that was widely treated as permissive until its August 2026 AUP update put sexually explicit generation out of bounds.

Price check
Wan 2.6 on Novita listed at about $0.100/s for 720p (≈$0.50 per 5-second clip); 18models Wan 2.7 720p is $0.113/s and HappyHorse 480p $0.048/s. On images Novita is cheaper (Z-Image ≈$0.005, Qwen-Image ≈$0.02 vs our $0.017 / $0.035) — but neither can be used for explicit output there.
When Novita is the better choice
If your workload is strictly SFW and image-heavy, Novita's image prices are lower and its catalog is broader. The moment adult output is part of the product, their terms no longer cover you.

- Read the Content Policy — minors and real people are banned absolutely and screened; if your app respects those lines, nothing else changes.
