18models vs Segmind for Seedance 2.5 and NSFW generation

Comparison verified 2026-08-19 · Third-party facts quoted from public terms and price lists · Corrections within 24 h

Segmind's August 2026 pitch is that it is the "only" uncensored channel for Seedance 2.5, at $10.97 per million tokens. As of 2026-08-19, 18models serves the same Seedance 2.5 model at $10.70 per million output tokens — about 2.5% lower — alongside Wan 2.7 / 3.0, the exclusive HappyHorse family, Qwen-Image and Z-Image, with NSFW output permitted under a published content policy. On Seedance specifically, model-level checks from the upstream provider apply on both platforms.

Segmind is a serverless model cloud that has leaned into 'uncensored' search terms; its catalog overlaps ours mainly on Seedance 2.5.
