KagentenSeedance 2.5 4K, ByteDance's new flagship video model announced on October 23, 2026, is not something you can use yet. Access is limited to a small group of enterprise partners trialing it through Volcano Engine, ByteDance's cloud arm, and there is no public price — because there is no public version. Below is the straight answer on where the model can actually be used right now, what it will likely cost when it opens up, what genuinely improves over the base Seedance 2.5, and the high-resolution video you can generate today while the 4K edition sits behind closed doors.
Seedance 2.5 4K is the new top tier of ByteDance's Seedance 2.5 video-generation family. Per the October 23 announcement, it is the strongest model of the 2.5 generation, specifically trained on facial expressions, subtle movement, and fine surface detail, and it outputs 10-bit color — richer gradation and smoother transitions aimed at cinema-scale screens rather than phone feeds.
Two features matter most in practice:
The model's screen debut was the short film Otter Is Nobody 2, and the first customer works — the animated PVs Hua Long Ji and Yang Jian — already came out of film and post-production studios trialing the model.
Short answer: only through ByteDance itself, and only if you're an enterprise partner. As of October 23, 2026:
Expect "Seedance 2.5 4K" marketing to appear on third-party sites before genuine access does. Until a real 4K SKU shows up on an API marketplace or ByteDance opens the trial publicly, treat any "try 4K today" claim with skepticism.
Nobody outside ByteDance's partner program knows yet. There is no published price, and we won't invent one.
What's reasonable to expect, based on how this model family is billed everywhere it is currently available through APIs:
We'll update this section with a dated source the moment a public 4K price exists, whether from ByteDance directly or from an API marketplace.
All quality evidence so far is ByteDance-published, so weight it accordingly:
Independent benchmarks don't exist yet, and we haven't tested the model — almost nobody outside the partner studios has. The base Seedance 2.5 was already a strong motion model, and the 4K edition raises the ceiling on top of it. Whether it's worth the wait comes down to one question: does your video actually end up on a big screen? If it's for the web, social, or product pages, 1080p remains the working standard — and that you can generate today.
Kagenten — the platform this article lives on — generates video from text prompts or images, with four models in the Video Agent. Current prices, in platform credits (as of October 2026):
| Model | Max resolution | 5-second video |
|---|---|---|
| Seedance 2.0 Mini | 720p | 200 credits |
| MiniMax H3 | 2K | 350 credits |
| Kling 3.0 Turbo | 1080p | 450 credits |
| Wan 3.0 | 1080p | 600 credits |
Ten- and fifteen-second renders scale from those numbers, new accounts get free starter credits to test with, and Video Agent handles text-to-video and image-to-video in one place. Here's a sample generated on the platform:
Be clear-eyed about the ceiling: these models top out at 2K, and no publicly verifiable tool renders true Seedance 2.5 4K today. For cinema delivery, waiting for the real thing is a defensible call. For everything else, 1080p is already the standard your viewers will actually watch.
When any of this changes, we update the relevant section above and date the change.
Nowhere as a regular user, yet. As of October 23, 2026 it is in trial with selected enterprise partners via ByteDance's Volcano Engine, with broader access promised but not dated.
There is no published price. Expect per-second billing with 4K priced at the top of the resolution ladder, and use Draft mode — 480P samples, then one final 4K render — to keep iteration costs down once you get access.
No. We checked KIE on October 23, 2026: its Seedance 2.5 listing tops out at 1080p, with no 4K option listed.
No. The 4K edition is a separately trained flagship focused on big-screen detail, 10-bit color, and reference fidelity. The base Seedance 2.5 is the widely available version, topping out at 1080p on API marketplaces.
1080p is the practical standard. On Kagenten, a 5-second 1080p clip starts at 450 credits (Kling 3.0 Turbo), Wan 3.0 does 1080p at 600 credits, and MiniMax H3 renders 2K from 350 credits.
