Seedance 2.5 4K: not a resolution tier — a separate model enterprise customers get first
The API's own tables end Seedance 2.5 at 1080p with Not supported printed in the 4K cell; the official channel's 4K video describes a separate 2.5-generation model that is open only to selected enterprise customers, with no API date published.

Seedance 2.5 does not output 4K through the public API, and that is not a stale page or a contradiction — 4K belongs to a separate model in the same generation that is currently available only to selected enterprise customers, with no API date announced. The pricing table prints Not supported in the 2.5 row's 4K cell, the API's resolution parameter stops at 1080p, and the official video announcing "Seedance 2.5 4K" describes a distinct model with its own name. Three different things travel under the phrase "Seedance 2.5 4K" online — the enterprise model, third-party upscaling, and the 2.0 series' own 4K output — and mixing them is how wrong answers spread.
Everything document-side on this page comes from the public BytePlus ModelArk pricing page and the Dreamina Seedance 2.5 tutorial, both read on 29 October 2026. Video-side evidence is the description of the official BytePlus YouTube video, captured on 30 October 2026 and re-read on 6 November 2026 with the wording unchanged. No account was registered, no enterprise channel was contacted, and no API call was made. Where a claim belongs to a third party rather than an official page, it is marked as one.
What the API documentation actually prints
The pricing page's video table has one row per model and one column per resolution. The row for dreamina-seedance-2-5-260628 reads, left to right: $10.70 for 480p and 720p, $11.7 for 1080p, and then Not supported in the 4K column — with a second Not supported in the offline-inference column. The 2.0 row, by contrast, carries a token rate in the 4K column. Whatever 4K costs, it is priced on the 2.0 row and absent from the 2.5 one, on the page read 29 October 2026.
The tutorial page narrows it further. The resolution parameter's optional values are listed as 480p (8-bit colour depth), 720p (8-bit), and 1080p (10-bit), with 720p as the default, and a note adds that 2.5's 1080p output uses 10-bit colour depth with H.265/HEVC encoding. The capabilities table on the same page puts the two generations side by side, and the split is clean: Seedance 2.5's column tops out at 1080p (10-bit), while the Seedance 2.0 column lists 4k (10-bit colour depth) as a fourth output option. The two Fast and Mini variants stop at 720p.
One adjacent fact is easy to misread. The same tutorial's input requirements say reference videos may be 480p, 720p, 1080p, or 4k — but that is the resolution of input video the model can accept as reference material, not what it can output. Feeding 2.5 a 4K reference clip does not make 2.5 a 4K generator, and the output parameter's list remains three values long.
Draft mode adds a related ceiling. The tutorial states that only 480p Draft videos can be generated, and that "when generating a final video from a Draft video, Dreamina Seedance 2.5 currently supports only 1080p output. Setting another resolution causes an error." Read 29 October 2026, that sentence bounds the Draft workflow's top end at 1080p on the public API.
What the official video announces
On 23 October 2026 the official BytePlus YouTube channel published a video titled "Seedance 2.5 4K | Built for the Big Screen". Its description, captured on 30 October 2026 (when the page showed 138,332 views) and re-read on 6 November 2026 with the wording unchanged, opens with "Meet Seedance 2.5 4K" and calls it "the most capable model in the Seedance 2.5 generation" — a separate model with its own name, not a setting on the existing one.
The same description gives the specification and the availability in two sentences: "With 4K output and 10-bit colour depth, Seedance 2.5 4K delivers clearer textures and smoother colour transitions", and then, at the end: "Currently available to selected enterprise customers. Stay tuned for updates on API availability." No frame rate is stated, no price is stated, and no date for API access is stated — the description does not publish one, and this page does not infer one.
The description also assigns Draft mode a role in the 4K workflow: "Draft mode lets creators test storyboards and refine shots using lower-cost 480p previews before generating the final version in 4K." Set beside the documentation's "currently supports only 1080p output" line for Draft finals, this is the same split again — the video describes the enterprise workflow, the documentation describes the public one — and this page keeps both sentences without reconciling them.
Why the two documents do not contradict each other
The instinct on reading these side by side is to call one of them stale. Neither needs to be. The pricing table and the tutorial describe what the public API sells today; the video describes a model that exists but is not on that API yet, offered first to selected enterprise customers. An enterprise-first release with a pending API date is consistent with a pricing table that has nothing to charge for in the 4K cell.
What the public record does not contain: a price for Seedance 2.5 4K in any currency, an API release date, a frame rate for 4K output, or any statement about which resolutions the enterprise model accepts as input. Each of those is genuinely unpublished as of 6 November 2026, and a page that fills any of them in with an estimate is doing arithmetic the vendor has not done.
What the search results around it are selling
The autocomplete suggestions collected on 30 October 2026 included does seedance 2.5 have 4k, does seedance 2.5 support 4k, when is seedance 2.5 4k coming, seedance 2.5 4k api, seedance 2.5 4k price, and seedance 2.5 native 4k — six different phrasings of one question, and the word "native" in the last one is exactly the distinction this page is drawing. The suggestions show people are asking; they are not evidence about the answer.
The results filling that space are worth sorting into their three piles. A SeaArt channel video titled "Seedance 2.5 in 4K is now live on SeaArt" (336 views at capture, 30 October 2026) is a third-party platform's claim about its own service; this site has not verified what that service generates or at what resolution, so it stays a claim. A HitPaw tutorial titled "How to Enhance Seedance 2.5 Videos from 720P to 4K" describes upscaling an existing video, which is a different operation from generating 4K — a tool that enlarges a 720p output is not evidence that the model produced 4K pixels. And a Chinese-language video (5,799 views at capture) titling the topic "Seedance 2.5 is here! Seedance 2.0 outputs 4K directly" attaches 4K to the 2.0 series, which matches the official documentation's own table — a third-party source agreeing with the vendor page, for whatever that is worth.
The three piles answer three different questions: the enterprise model is real but not callable by the public; upscaling is a post-process that any tool can perform on any resolution; and the 2.0 series' 4K output is a published, priced capability of a different model generation. The next upscaler result that ranks for "Seedance 2.5 4K" is answering the second question while looking like it answers the first.
What this page does not settle
No enterprise channel was tested, so nothing here measures what Seedance 2.5 4K actually produces — quality, frame rate, duration limits, and pricing are all outside what public pages state. The SeaArt claim was not tested either, and no third-party 4K output was downloaded and inspected. The view counts quoted are the numbers shown at capture time and move constantly. The API date is unpublished, and this page will not project one.
Prices and availability change without announcement. Every document reading here is dated 29 October 2026 with the page it came from; the video description was read twice, on 30 October and 6 November 2026, and was identical both times. Re-read before quoting any of it.
