Seedance 2.5 Spicy vs Wan 3.0 Spicy: Tied Specs, Split Price

Both endpoints market themselves as "uncensored, full-featured" video generation. That used to translate into a real spec difference — one topped out lower than the other. It doesn't anymore. Once the resolution ceiling is tied, the decision comes down to price, and the two aren't close.

Key Takeaways

• Seedance 2.5 Spicy now supports 480p / 720p / 1080p — a correction from the older "720p max" understanding. Wan 3.0 Spicy has offered the same three tiers all along.
• Both run duration up to 30 seconds; Seedance 2.5 Spicy's ref2v variant also accepts -1 for auto-length.
• At matching resolution and duration, Wan 3.0 Spicy runs 2.5x-3.4x cheaper than Seedance 2.5 Spicy.
• Wan 3.0 Spicy's 15% Launch Week discount is a different number from Wan 3.0 plain's 25% discount — don't conflate the two.

Spec Parity: The Ceiling Is Tied

Seedance 2.5 Spicy's size field now enumerates 480p / 720p / 1080p — the same ceiling as Wan 3.0 Spicy. This is worth stating plainly because it's a change: Seedance 2.5 Spicy previously topped out lower. It doesn't now. Duration on both runs 2-30 (Seedance 2.5 Spicy) or 4-30 (Wan 3.0 Spicy) seconds, with Seedance 2.5 Spicy's ref2v variant additionally accepting -1 for an auto-determined length.

Neither endpoint is "the higher-spec" choice anymore. If you're picking between them on resolution alone, that reasoning no longer applies.

The Real Split: Price

Seedance 2.5 Spicy bills off a token formula — $0.01391 per 1K tokens, where tokens scale with resolution, duration, and frame rate (dropping to $0.00832/1K with video input) — and carries no discount badge. Wan 3.0 Spicy bills min(input video, 5s) + output duration at a flat per-second rate, already discounted 15% off list ($0.065/$0.130/$0.260 → $0.055/$0.110/$0.220).

Run the numbers on a 5-second clip and the gap is stark: at 720p, $1.51 (Seedance 2.5 Spicy) vs. $0.55 (Wan 3.0 Spicy). At 1080p, $3.696 vs. $1.10. That's 2.5x to 3.4x cheaper on Wan 3.0 Spicy, and the gap widens at higher resolution.

One capability note, not a pricing factor: Seedance 2.5 Spicy's ref2v variant accepts an audios reference array (1-10 clips) that its plain (non-Spicy) ref2v doesn't have. If a scene needs a locked voice alongside a locked face, that's a Seedance-specific extra — but it doesn't change the per-second math above.

A Directive Prompt on the Cheaper Endpoint

model: alibaba/wan-3.0-t2v-spicy
size: "1080p"
duration: 8
prompt: "cinematic close-up, warm bedroom lighting, slow camera pan,soft focus transitions between shots"

Same request shape as any other Wan 3.0 call — the discount doesn't require a different integration, just the -spicy suffix on the model string.

Developer Note

Both endpoints sit behind the same request shape as the rest of the Siray catalog — swap the model string between bytedance/seedance-2.5-t2v-spicy (or -ref2v-spicy) and alibaba/wan-3.0-t2v-spicy (or -i2v-spicy/-ref2v-spicy) and the rest of the call stays the same. One API key covers both.

⚠️ Don't mix up the discounts: Wan 3.0 plain gets 25% off during Launch Week; Wan 3.0 Spicy gets 15% off. This piece only covers the Spicy tier's 15% number — see our Wan 3.0 Launch Week pricing breakdown for the plain-tier 25% figure, which is a separate discount entirely.
