Seedance 2.5: release date, confirmed specs, and API access
Updated July 16, 2026
What ByteDance has officially confirmed
Seedance 2.5 was previewed on stage at Volcano Engine's developer conference on June 23, 2026. One capability was demonstrated and explicitly confirmed: 30-second single-shot generation — one continuous take, generated in a single pass. That is a structural change from Seedance 2.0, which builds longer videos by extending shorter segments.
That's the full list. Everything else you may have read — including on sites presenting themselves as official Seedance products — is unconfirmed.
How 2.5 differs from Seedance 2.0
The confirmed and best-supported differences, against 2.0's known capabilities:
| Seedance 2.0 (current) | Seedance 2.5 (confirmed/expected) | |
|---|---|---|
| Single-shot duration | 4–15s per segment, extendable | 30s confirmed |
| Reference inputs | Up to 9 images, 3 videos, 3 audio files | Expansion rumored, unconfirmed |
| Max resolution | 4K | 4K expected; 10-bit color rumored |
| Native audio | Yes | Expected to carry over |
Full breakdown with sample clips: Seedance 2.5 vs 2.0. We'll run identical prompts on both models within 24 hours of release.
The baseline: what Seedance 2.0 produces today
To calibrate expectations for 2.5, here is the current model's output with the exact prompts used — multi-modal referencing is the line's signature capability:
Choreographed fight scene
Reference the character actions and camera language from Video 1, generate a fight scene between Image 2 and Image 1. Image 2 is the character on the left, Image 1 is the character on the right. With intense background music.
Product ad: golden horse pendant
Reference the running form of the horse from Video 1, generate a golden horse galloping on a grassland, then freeze-frame its magnificent running pose, transforming into a horse-shaped gold pendant.
Logo reveal in a neon skyline
The background is a neon-lit futuristic urban sky corridor with vehicles and holographic ads intertwined. Reference the girl from Image 2, first use a medium shot to show the girl releasing silver floating lanterns with holographic projections, then the camera pulls back to reveal floating lanterns filling the sky. The scene gradually blurs, then the Logo from Image 1 appears.
FPV dive concept video
Reference the camera movement from Video 1 to create a concept video for a tech park. Use the high-rise building from Image 1 as the visual center, with the same first-person diving perspective, highlighting the tech aesthetic of the park.

Release timeline
- Jun 23, 2026— Official preview at Volcano Engine's conference; 30s single-shot generation demonstrated.
- Late Jul – early Aug 2026 (estimate)— Expected public release, based on ByteDance's historical preview-to-launch gap. Not an official date.
- Launch + days — Third-party API availability (kie.ai, fal.ai) typically follows Volcano Engine within days for Seedance releases.
Where the API will land first
Based on how Seedance 2.0 rolled out, expect this order: Volcano Engine / BytePlus(ByteDance's own cloud) first, then aggregators like kie.ai and fal.ai. Consumer access runs through Jimeng (即梦) domestically and Dreamina internationally.

Frequently asked questions
- When is Seedance 2.5 coming out?
- ByteDance has not announced an exact date. The model was officially previewed on June 23, 2026 at Volcano Engine's developer conference. Based on the gap between preview and release for previous Seedance versions, most observers expect late July to early August 2026. We update this page the day anything changes.
- What has ByteDance officially confirmed about Seedance 2.5?
- The on-stage preview confirmed 30-second single-shot generation — up from the segment-based approach in Seedance 2.0. Other circulating specs (native 4K, expanded reference inputs) have not been officially confirmed and should be treated as rumors.
- Will Seedance 2.5 have an API?
- Almost certainly. Seedance 2.0 is available through Volcano Engine/BytePlus and third-party providers like kie.ai and fal.ai. We expect the same channels for 2.5, with Volcano Engine first and third parties following within days. Note: global API availability for ByteDance video models has been interrupted before over copyright disputes, so a delay outside China is a real risk.
- How much will Seedance 2.5 cost?
- Unknown until launch. Seedance 2.0 API pricing lands well below Google's Veo family per clip, and ByteDance has consistently priced aggressively. We'll publish a measured cost-per-clip test within hours of API availability.
- Can I try Seedance 2.5 for free?
- Not yet — it isn't released. When it ships, official access will be via Jimeng/Dreamina and Volcano Engine. We'll offer a free watermarked test generation on this site the day the API opens. Join the waitlist on our generate page to get one email at launch.
