Seedance 2.5 Spicy is live on Siray. The endpoint family covers text-to-video, image-to-video, and reference-driven video, bringing the full three-variant set to the adult creative pipeline.
What's in the Endpoint Family
The three variants are bytedance/seedance-2.5-t2v-spicy, bytedance/seedance-2.5-i2v-spicy, and bytedance/seedance-2.5-ref2v-spicy. All three share the same core parameters.
Parameter | Value |
size | 480p, 720p |
duration | 4–30 seconds (ref2v also accepts -1) |
audio_enable | Available |
Resolution ceiling | 720p — no 1080p, no 4K |
The 30-second duration ceiling is the standout capability here. Alongside Wan 3.0 Spicy, it is the longest single-call generation available on Siray's uncensored endpoints. That length matters for scenes with extended motion, slow builds, or narratives that do not want a hard cut in the middle.
The Trade-Off to Know
30 seconds at 720p is a real exchange. Seedance 2.0 Spicy reaches 1080p and 4K; Wan 3.0 Spicy reaches 1080p. Seedance 2.5 Spicy tops out at 720p while matching the longest duration on the platform.Which one fits depends on what the project needs:
- Longest duration, resolution not critical → 2.5 Spicy or Wan 3.0 Spicy
- Maximum resolution up to 4K → 2.0 Spicy
- 30 seconds and 1080p, with published per-tier rates → Wan 3.0 Spicy
- Multiple requirements in one project → generate per-scene and cut in post

Pricing
Billing rates for Seedance 2.5 Spicy have not been published. The rate is not the same as 2.0 Spicy (which has a different per-second structure) and should not be estimated from the general 2.5 endpoints either — the Spicy variants use separate fee schedules. Run a short test clip to calibrate your budget before scaling.
