Seedance Version History — From 1.0 to 2.5 (and the Seedance 3.0 release date question)
Every Seedance video model release from ByteDance on one timeline. Seedance 2.5 was officially launched by ByteDance Seed on July 31, 2026 and is now API-accessible through current BytePlus documentation under dreamina-seedance-2-5-260628. This site's generator still uses Seedance 2.0 and Seedance 2.0 Fast. Seedance 3.0 has no announced release date.

30-Second Verdict
- 1Seedance 2.5 was officially launched by ByteDance Seed on July 31, 2026. The launch post said BytePlus ModelArk API access was coming soon; BytePlus subsequently published live API documentation listing `dreamina-seedance-2-5-260628` as a supported enhanced model.
- 2Current verified status — September 8, 2026: Seedance 2.5 is API-accessible through BytePlus documentation. Seedance 2.0 remains a supported Seedance 2.x API model, and this site's generator still uses Seedance 2.0 and Seedance 2.0 Fast.
- 3Seedance 3.0 has no announced release date. As of August 2, 2026, ByteDance has not published any roadmap, specifications, or timeline for a Seedance 3.0 release — any "Seedance 3.0 release date" you see quoted today is speculation, not reporting.

Seedance 2.1
HistoricalRumored May 2026 — superseded by 2.5 launch
A May 2026 Pandaily report cited ByteDance sources promising a ~20% quality lift over 2.0. The 2.1 label never became a shipping product and was superseded by the Seedance 2.5 announcement (Jun 23, 2026) and official launch (Jul 31, 2026).
- Never formally launched — no Volcengine Ark page, no consumer surface, no API access
- Reported ~20% quality lift target (Pandaily, May 2026)
- Superseded in ByteDance's public roadmap by Seedance 2.5
Seedance 2.5

Seedance 3.0
Speculative · Not announcedNo announced release date
ByteDance has not announced a Seedance 3.0 release date. As of August 2, 2026, no public roadmap, no specifications, no timeline, and no Volcengine Ark placeholder for Seedance 3.0 exists. The newest official Seedance generation is 2.5.
- Based on ByteDance's historical cadence (1.0 → 2.0: 8 months; 2.0 → 2.5 launch: 5.5 months), a 3.0 release would not be expected before 2027 at the earliest
- Any "Seedance 3.0 release date" or specifications quoted today are speculation, not reporting
- Sites selling "Seedance 3.0 access" (e.g. seedance3ai.net and similar) are unaffiliated with ByteDance
Seedance 2.5 API is documented live by BytePlus
Seedance 2.5 launched on Jimeng AI and Doubao Pro on July 31, 2026, but the BytePlus ModelArk endpoint is not yet callable. 2.5 keeps the same unified multimodal audio-video architecture as 2.0, so prompts, camera direction, and reference-input patterns you learn on 2.0 will carry forward.

Side-by-side capability comparison
Capabilities for Seedance 1.0, 2.0, and the officially launched 2.5 across seven dimensions. 2.5 entries reflect the ByteDance Seed launch post (July 31, 2026) and the BytePlus ModelArk model card and rate card published the same day.
| Capability | Seedance 1.0 | Seedance 2.0 (current API) | Seedance 2.5 (launched · API pending) |
|---|---|---|---|
| Max clip duration (single pass) | 5-8 seconds | 4-15 seconds | 30 seconds (confirmed by launch post, Jul 31, 2026) + multi-round extension for longer sequences |
| Max resolution | 720p | Up to 2K (native 480p/720p/1080p/4K rate rows documented) | 480p and 720p in the published rate card; 1080p and 4K not confirmed in launch materials |
| Native audio | No | Yes (stereo, BGM + SFX + voiceover + lip-sync) | Yes — same unified multimodal audio-video architecture as 2.0, extended to 30-second clips |
| Multimodal reference input | Text + single image | @-reference: 9 images + 3 videos + 3 audio | Up to 30 images + 10 videos + 10 audio clips per request; adds clay-render, motion, and creative reference types |
| Region-level / timestamp editing | No | No | Timestamp-level and camera-perspective editing (confirmed by launch post) |
| API access | None (consumer only) | Public on Volcengine Ark (since April 2, 2026); `dreamina-seedance-2-0-260128` on BytePlus ModelArk | API-accessible as of Sep 8, 2026 — `dreamina-seedance-2-5-260628`; 480p / 720p, 24 fps, 4–30 seconds |
| Pricing model | Free inside Doubao / Jimeng | Pay-per-token (~$0.14/sec generated at 720p) | Rate card published: ~$6.40 / $10.70 per million tokens (with / without video input); ~$0.103/s at 480p and ~$0.231/s at 720p per BytePlus ModelArk documentation |
What changed: Seedance 1.0 → 2.0
The 1.0 → 2.0 jump (8 months) was the biggest leap in the Seedance line so far. 1.0 maxed out at 5-8 second clips, 720p, with no native audio — clips were silent by default and had to be dubbed in post. 2.0 added native synchronized stereo audio in a single pass: background music, sound effects, voiceover, and lip-sync, all generated alongside the video.
The other 2.0 headline change was the @-reference multimodal input: a single generation request can now reference up to 9 images, 3 videos, and 3 audio clips simultaneously. This is what makes 2.0 viable for consistent-character storytelling and product-shot recreation — both of which 1.0 struggled with because it could only condition on a single image at a time.
The third big change was distribution: 1.0 was consumer-only (Doubao, Jimeng), with no public API. 2.0 opened a pay-per-token public-beta API on Volcengine Ark on April 2, 2026, at roughly $0.14 per second of generated video. That made 2.0 the first Seedance version a non-Chinese developer could integrate into a product without going through Chinese consumer accounts.
What shipped: Seedance 2.0 → 2.5
Seedance 2.5 was officially launched by ByteDance Seed on July 31, 2026 with the post "One-take Creation, Flexible Referencing: Introducing Seedance 2.5." Same-day TechNode coverage confirmed the scope: 30-second high-quality audio-video clips in a single pass with multi-round extension for longer sequences, reference input of up to 30 images + 10 videos + 10 audio clips per request, timestamp-level and camera-perspective editing, and improved shot transitions.
The rollout started on Jimeng AI and the Pro version of Doubao (both China-facing consumer surfaces). BytePlus ModelArk published the 2.5 model card dreamina-seedance-2-5-260628 and a token rate card at ~$6.40 / $10.70 per million tokens (with / without video input), but its own console displays "The Model Playground and API access will be available soon" above the request example, and its cURL sample still calls the 2.0 endpoint. As of August 2, 2026, no callable 2.5 API endpoint exists — third-party reports from July 16, 2026 claiming an already-open BytePlus 2.5 API are not supported by any official BytePlus page checked against this timeline.
The 2.5 release is a capability expansion built on the 2.0 architecture, not a redesign. The unified multimodal audio-video pipeline, prompt syntax, and reference-input mechanism all carry forward. That makes 2.0 prompt-engineering work and workflow investment effectively forward-compatible on day one of the eventual ModelArk endpoint opening.
Current BytePlus documentation confirms 480p and 720p API output at 24 fps for 4–30 seconds. It does not establish native 4K output for this API channel. Exact enterprise-volume pricing and named DCC-tool integrations require separate verification.

Seedance 2.1 release date
Seedance 2.1 was never released. ByteDance jumped from 2.0 directly to 2.5.
No official Seedance 2.1 release exists. It was superseded by Seedance 2.5, which is the newest official and API-accessible generation. Seedance 2.0 remains supported and is the runtime used by this site.
If you arrived here searching "Seedance 2.1 release date," the short answer is: the version label you are looking for is 2.5, not 2.1. The ~20% quality lift the Pandaily 2.1 rumor cited overlaps directionally with what ByteDance eventually shipped in 2.5 (30-second single-pass clips, expanded reference pool, timestamp editing), but the label 2.1 was never published as a first-party endpoint. Sites advertising "Seedance 2.1 release date" or "Seedance 2.1 access" are speculating unless they cite a first-party endpoint.

Seedance 3.0 release date
Seedance 3.0 has no announced release date.
As of August 2, 2026, ByteDance has not published any roadmap, specifications, or timeline for Seedance 3.0. There is no Volcengine Ark placeholder, no BytePlus ModelArk model card, no ByteDance Seed research blog announcement, and no consumer surface for a Seedance 3.0 model. The newest official Seedance generation is Seedance 2.5 (officially launched July 31, 2026; BytePlus API documented live). This site's current runtime is Seedance 2.0 (released February 12, 2026).
Based on ByteDance's release cadence — 1.0 (June 2025) → 2.0 (February 2026, 8 months) → 2.5 launched (July 31, 2026, 5.5 months after 2.0) — a Seedance 3.0 release would not be expected before 2027 at the earliest. Any "Seedance 3.0 release date" you see quoted today is speculation, not reporting. Sites offering "Seedance 3.0 access" (such as seedance3ai.net and similar) are unaffiliated with ByteDance and are not running an official Seedance 3.0 model — because no such model exists publicly.

Frequently asked questions
How often does ByteDance release a new Seedance version?
Based on the public release history, roughly every 4-8 months and accelerating. Seedance 1.0 launched in June 2025; an interim 1.5 Pro followed in late 2025; Seedance 2.0 launched on February 12, 2026 (8 months after 1.0); Seedance 2.5 was announced on June 23, 2026 and officially launched on July 31, 2026 (5.5 months after 2.0). ByteDance has not committed to a public release schedule.
Should I wait for the Seedance 2.5 API or use 2.0 today?
Choose the documented 2.5 endpoint for new work that needs its 30-second duration and enhanced reference/editing features. Keep 2.0 for existing compatible integrations. This site currently uses Seedance 2.0 and Seedance 2.0 Fast; BytePlus API availability does not imply that this site has switched runtime models.
Will my Seedance 2.0 prompts and workflows still work on 2.5?
2.5 keeps the same unified multimodal audio-video architecture as 2.0, so single-shot text-to-video, image-to-video, and audio-referenced prompts should carry forward directionally. The concrete changes to plan for: 30-second single-pass clips (vs 15s), a much larger reference pool (30 images + 10 videos + 10 audio vs 9 + 3 + 3), and new reference types (clay-render, motion, creative). Timestamp-level editing is a new capability, not a replacement for existing prompt patterns. Keep prompts modular so subject / camera / audio blocks can be recombined once the 2.5 API opens.
How is Seedance 2.5 priced compared to 2.0?
BytePlus ModelArk published a 2.5 token rate card at roughly $6.40 per million tokens (with video input) and $10.70 per million tokens (without video input). Third-party integrators tracking the rate card have derived approximate per-clip prices of $0.514 at 480p ($0.103/s) and $1.156 at 720p ($0.231/s) — roughly 50% above the equivalent 2.0 tier. No 1080p or 4K rate row has been published for 2.5. These prices reflect the ModelArk rate card as of August 2, 2026; the endpoint itself is not yet callable, and Volcengine (¥42 / ¥70 per million tokens for `doubao-seedance-2-5-260628`) uses CNY billing.
Where does Seedance 2.5 launch the public API?
BytePlus is the international API channel named in the July 31 launch post. Current BytePlus enhanced video-generation documentation lists `dreamina-seedance-2-5-260628` as supported.
Is "Seedance Pro 2.0" or "Seedance 2.7" a real version?
No. The official ByteDance Seedance line includes 1.0, 1.5 Pro, 2.0, and the latest generation 2.5. There is no official "Seedance 2.0 Pro," "Seedance 2.7," or "Seedance 3.0" release.
If Seedance 3.0 has not been announced, why does this page mention it?
Because users actively search for "Seedance 3.0 release date" — and an honest answer ("no announced release date, no public information; newest generation is 2.5") is more useful than letting that query route to misinformation. This page is the canonical "no, there is no Seedance 3.0 release date" answer for the 3.0 query, with the same source-cited treatment applied to confirmed versions like 2.0 and 2.5.
How is this page kept up to date?
This page is reviewed at least every 14 days and updated immediately when ByteDance publishes new Seedance information. The "Last updated" date in the page header and the schema.org dateModified field both reflect the most recent factual update. The most recent update on August 2, 2026 records the Seedance 2.5 official launch (July 31, 2026), the confirmed 30-second / 30-image capability envelope, the BytePlus ModelArk "coming soon" API status, and the published 2.5 rate card.
