The five Seedance alternatives worth comparing are Veo 3.1, Veo 3.1 Fast, Kling 3.0, Kling 2.6, and Runway Gen-4.5. Every one publishes a per-second API rate, and at 720p those rates span roughly 10x. Check the route before you switch models: the same Seedance 2.0 clip costs $0.15 or $0.36 per second depending on who you buy it through. Runway is one of those routes, and Runway alternatives covers what its API carries.
A “best for” column does not tell you what a 10-second clip costs. The provider’s own price list does.
This guide uses those prices. Every number below comes from the provider’s own pricing page or API reference, checked in September 2026, with the source next to it. Then it covers the route. The same model sells at different prices depending on who you buy it through, and that gap can be bigger than the gap between models.
Key Takeaways
-
Seedance has a newer version. ByteDance launched Seedance 2.5 on 31 July 2026, and its BytePlus API is live (seed.bytedance.com, September 2026). This guide compares against Seedance 2.0, which BytePlus still sells: 480p through 4K, 4 to 15 second clips, and audio on by default.
-
The route can cost more than the model. Seedance 2.0 at 720p is $0.15/s direct from BytePlus and $0.36/s through Runway’s API. Same model, 2.4x spread.
-
Veo 3.1 Lite has the lowest rate with audio here. $0.05/s at 720p, against $0.10/s for Veo 3.1 Fast and $0.40/s for Veo 3.1 (ai.google.dev, September 2026).
-
Kling 2.6 has the lowest 720p rate in this comparison. $0.042/s at 720p without audio, rising to $0.14/s at 1080p with native audio (kling.ai, September 2026).
-
Sora 2 Pro is not on this list. OpenAI removed Sora 2 and Sora 2 Pro from its API on 24 September 2026 (OpenAI API deprecations, accessed September 2026).
What Seedance 2.0 does
Seedance 2.0 is ByteDance’s video model, sold through BytePlus ModelArk. It generates 480p, 720p, 1080p, and 4K, with 4K in 10-bit color, at any whole number of seconds from 4 to 15. Audio is on by default, and a flag turns it off (docs.byteplus.com, September 2026).
Three capabilities set it apart in its published spec. It takes multimodal references: up to 9 images, 3 video clips and 3 audio clips in one generation, and audio-only input is not allowed (seed.bytedance.com, September 2026). It offers seven aspect ratio settings: 21:9, 16:9, 4:3, 1:1, 3:4, 9:16, and adaptive. And it cuts between shots inside one generation, so a short sequence can arrive as one file.
Kling 3.0 is the other model here that accepts a video as input for a subject, through its Elements. It also cuts between shots inside one generation.
Three limits are worth planning around. The API returns mono audio, although the launch post describes dual-channel audio. BytePlus does not accept reference images or videos that contain real human faces, apart from a few routes such as consented people who pass a face check (docs.byteplus.com, September 2026). And the BytePlus API runs in one region, ap-southeast-1, with an availability list that leaves out the United States, China, India and Russia (docs.byteplus.com, September 2026).
Seedance 2.0 is one of the video models DesignerBox runs, which matters for the route question below.
The 5 Seedance alternatives compared
1. Veo 3.1 (Google): best for dialogue and long-form
Veo 3.1 generates 4, 6 or 8 second clips at 720p by default, with 1080p and 4K at 8 seconds only. Audio, including dialogue, is always on, and the price already includes it (ai.google.dev, September 2026). Google also says natural spoken audio for shorter speech “remains an area of active development” (deepmind.google, September 2026).
Its distinguishing feature is extension. In the Gemini API, a Veo 3.1 clip extends by 7 seconds at a time, up to 20 times, for up to 148 seconds, at 720p only. Google Cloud documents a different limit of 37 seconds. Inputs cover text, a first frame, a first and last frame, and up to 3 reference images of one person, character or product.
Two changes to know about. Google now names Gemini Omni Flash its default video model in the Gemini API, and keeps Veo 3.1 for scene extension and last-frame control (ai.google.dev, September 2026). Google also lists 22 October 2026 as the earliest shutdown date for the Veo 3.1 preview models in the Gemini API, and names Gemini Omni Flash as the replacement (Gemini API deprecations, October 2026). That date covers Veo 3.1, Veo 3.1 Fast and Veo 3.1 Lite. On Google Cloud, the generally available Veo 3.1 models list a retirement date of 17 November 2026 or later (docs.cloud.google.com, October 2026).
Best for: scripted spots with dialogue, and anything that needs to run past 15 seconds.
2. Veo 3.1 Fast (Google): best for volume testing
Same family, a quarter of the price at 720p and half the price at 4K. Veo 3.1 Fast is $0.10/s at 720p, $0.12/s at 1080p, and $0.30/s at 4K in the Gemini API, with audio included at every tier (ai.google.dev, September 2026).
For ad testing where you need 20 variants and only two will survive the first round, this is the rate that makes the math work. Google also sells Veo 3.1 Lite at $0.05/s for 720p and $0.08/s for 1080p. Lite has no 4K, no extension and no reference images.
Best for: high-variant ad testing where per-clip cost decides how many concepts you can try.
3. Kling 3.0 (Kuaishou): best for multi-shot clips up to 15 seconds
Kuaishou announced Kling 3.0 on 5 February 2026 with 3 to 15 second clips and 1 to 6 shots per clip, and added native 4K on 23 April 2026 (kling.ai, September 2026). It outputs 720p, 1080p or 4K, with dialogue in Chinese, English, Japanese, Korean and Spanish.
It holds a subject across shots with Elements. You can add up to 3 Elements per clip, and each one is built from a video or from 2 to 4 reference images (kling.ai, September 2026).
Kling’s API list price runs from $0.084 to $0.168 a second by resolution and audio, and $0.42 a second at 4K (kling.ai, September 2026). Kuaishou also shipped Kling 3.0 Turbo on 17 June 2026, at 720p or 1080p with the same 3 to 15 second range (kling.ai, September 2026).
Best for: a take longer than 8 seconds, a short multi-shot sequence in one file, and 1080p vertical clips with sound.
4. Kling 2.6 (Kuaishou): best for cost per silent clip
Kling 2.6 tops out at 1080p and generates 5 or 10 second clips only, with no durations in between. Native audio is off by default and needs 1080p, so 720p clips are silent (kling.ai, September 2026). Speech is in English or Chinese.
The pricing is the story. At $0.042/s for 720p without audio, it has the lowest 720p rate in this comparison, and Kling 2.5 Turbo lists the same $0.042. Turn native audio on and you move to 1080p at $0.14/s. First-and-last-frame input runs at 1080p, silent. Kling 2.6 takes no reference images (kling.ai, September 2026).
Best for: silent B-roll, product motion, and looping social where you add sound in the edit.
5. Runway Gen-4.5: best for teams already working in Runway
Runway’s published spec for Gen-4.5 lists 720p output, 2 to 10 second durations, 24 or 25 fps, and text or a first frame as input (help.runwayml.com, September 2026). Image-to-video offers six aspect ratios, including 21:9. Through Runway’s API it costs $0.12 a second (docs.dev.runwayml.com, September 2026).
Runway says “Objects move with realistic weight, momentum and force” in Gen-4.5 (runway.com, September 2026). Read third-party spec pages carefully. Runway’s current spec and API list no audio output. Runway announced native audio for Gen-4.5 in December 2025, but it is not documented as shipped. 4K comes from a separate upscale step, and Gen-4.5 takes no reference images.
Best for: teams already inside Runway’s editor who direct a shot from its first frame.
What every model costs per second
Every rate below is the provider’s own published API price, checked in September 2026. Audio is marked, because a silent clip and a clip with dialogue are different products.
| Model | Provider | Max resolution | Duration | Native audio | Lowest listed rate | Top-res rate |
|---|---|---|---|---|---|---|
| Seedance 2.0 | ByteDance | 4K (10-bit) | 4 to 15s | Yes, on by default | $0.07/s (480p) | $0.78/s (4K) |
| Seedance 2.0 Fast | ByteDance | 720p | 4 to 15s | Yes | $0.06/s (480p) | $0.12/s (720p) |
| Seedance 2.0 Mini | ByteDance | 720p | 4 to 15s | Yes | $0.04/s (480p) | $0.08/s (720p) |
| Veo 3.1 | 4K | 4, 6 or 8s | Yes, always on | $0.40/s (720p) | $0.60/s (4K) | |
| Veo 3.1 Fast | 4K | 4, 6 or 8s | Yes, always on | $0.10/s (720p) | $0.30/s (4K) | |
| Veo 3.1 Lite | 1080p | 4, 6 or 8s | Yes, always on | $0.05/s (720p) | $0.08/s (1080p) | |
| Kling 3.0 | Kuaishou | 4K | 3 to 15s | Yes | $0.084/s | $0.42/s (4K) |
| Kling 2.6 | Kuaishou | 1080p | 5 or 10s only | Yes, 1080p only | $0.042/s (720p, silent) | $0.14/s (1080p, audio) |
| Runway Gen-4.5 | Runway | 720p | 2 to 10s | Not documented as shipped | $0.12/s (720p) | $0.12/s (720p) |
Sources: BytePlus ModelArk pricing, Gemini API pricing, Kling API pricing, Runway API pricing. All checked September 2026. BytePlus prints its rates as estimates for a 5-second 16:9 clip and bills per million tokens. Its temporary discounts on Fast and Mini, for enterprise users, are dated 7 August to 7 October 2026 and are not in this table.
Read the top-res column before the lowest one. Veo 3.1 at 4K is $0.60/s, so a single 8 second clip is $4.80. Kling 2.6 at 720p silent is $0.042/s, so a 10 second clip is 42 cents. Per second, that is a 14x range.
The route costs more than the model
Seedance 2.0 is one model with one set of weights, and it sells at different prices depending on who you buy it through. At 720p, BytePlus charges $0.15 a second direct and Runway’s API charges $0.36.
| Route | Seedance 2.0 at 720p | Seedance 2.0 at 1080p |
|---|---|---|
| BytePlus direct | $0.15/s | $0.37/s |
| Runway API | $0.36/s | $0.40/s |
Sources: BytePlus ModelArk pricing, Runway API pricing. Checked September 2026. Resale hosts set their own rates too: Replicate lists Seedance 2.0 at $0.18 a second (replicate.com/bytedance/seedance-2.0, September 2026).
Buying Seedance 2.0 through Runway’s API costs 2.4x what BytePlus charges at 720p, for the same model. That gap is larger than the gap between Seedance 2.0 and Veo 3.1 Fast, which means route selection can move your budget more than model selection does.
Region matters as well. The BytePlus availability list leaves out the United States, so a US team should check the route before it checks the model.
This is why “which alternative is better” is often the wrong first question. If the output suits you and the price or access does not, the answer may be a different route to the same model. Pick the route first. Then pick the model. If you compare whole creative platforms rather than API routes, OpenArt vs Higgsfield compares two of them on API access and licensing terms.
For the wider arithmetic across a full campaign rather than a single clip, see our breakdown of what AI video generation costs.
Open source Seedance alternatives
Open-weight Seedance alternatives exist, but the list is short. Alibaba’s Wan open weights on Hugging Face stop at Wan 2.2, released under Apache 2.0 (huggingface.co/Wan-AI, September 2026). Check Alibaba’s official repository before you plan around a later Wan version as open weights. Our guide to the Wan 2.5 API lists what Alibaba charges for the hosted versions.
Two other open-weight options are real. Lightricks publishes LTX-2.3, a 22B audio-video model that generates synchronized video and audio in one pass, under the LTX-2 Community License rather than Apache 2.0 (ltx.io, September 2026). That license is free below $10 million in annual company revenue. Lightricks released LTX-2.5 open weights on 11 August 2026 (ltx.io, accessed September 2026). Its LTX-2.x Community License sets the same $10 million threshold (LTX-2.x license, accessed September 2026). Tencent publishes HunyuanVideo-1.5 at 8.3B, generating 480p and 720p with upscaling to 1080p. Its community license does not apply in the EU, the UK or South Korea (github.com/Tencent-Hunyuan/HunyuanVideo-1.5, September 2026).
Read the license before you ship commercial work on any of them. Community licenses carry territory and use restrictions that Apache 2.0 does not, and those restrictions are the part that matters for a brand running paid ads.
These open-weight builds are the correct answer to a self-hosting question, and the wrong answer to a deadline.
How to pick by shot type
Model choice gets easier when you start from the shot instead of the brand.
Spoken dialogue to camera. Veo 3.1, for audio that is always on and the 148 second extension ceiling in the Gemini API.
Vertical social at 1080p with sound. Veo 3.1 at 1080p in 9:16, or Kling 3.0.
Product motion, silent, at volume. Kling 2.6 at $0.042/s. Add music and voiceover in the edit.
Twenty ad variants where eighteen get cut. Veo 3.1 Lite at $0.05/s, Seedance 2.0 Mini at $0.08/s, or Veo 3.1 Fast at $0.10/s.
Multi-shot sequence from one reference set. Seedance 2.0, for the widest reference input of the models here, or Kling 3.0, for up to 6 shots held together with Elements.
Anything longer than 15 seconds. Veo 3.1 with extension. Every other model here caps at 15 seconds or below in one generation. Outside this comparison, Seedance 2.5 reaches 30 seconds. Kling announced Kling 4.0 on 28 September 2026, with 3 to 30 second generations, and the full model is due in October 2026 (kling.ai, October 2026).

The model as one step in a workflow
In DesignerBox, a video model is one step in a workflow. You pick the model for each step when you build the workflow, and every run after that uses it (the model list). A template comes with its model already picked. You can change the model for one shot, and the rest of the workflow stays the same.
Video is billed in credits. An 8-second clip costs 40 to 560 credits, depending on the model. The cost is shown before the run, so you can test a sequence on a low-cost model first, then spend once on the take you ship.
Uploading your own photos and the commercial license start on the Pro plan. AI video, virtual try-on, upscaling, the image editor and the video editor start on the Premium plan. Team features, shared brand kits and white label are on the Ultra plan, and every plan below Ultra is one seat. Plans and credits are on the pricing page.
A six-shot ad rarely wants one model for all six, and the next product needs the same six shots again. You build the sequence once as a workflow, with a model set for each shot. A saved workflow runs the same way on the next product, and batch runs it over the whole sheet at once. You set the brand once, and the workflow reads it on every run. Shot three of product fifty then matches shot three of product one. The templates, the workflows, batch, the image editor, the video editor and the brand record sit together. The full workflow from the first product photo to the finished ad, in one subscription. For how credits relate to a plan, see what AI video costs.

FAQ
What is the best Seedance alternative?
There is no single best one, because each model leads on a different axis. Veo 3.1 leads on clip length through extension, Kling 3.0 on multi-shot clips up to 15 seconds, Kling 2.6 on cost per silent clip at $0.042/s, and Veo 3.1 Lite on price per clip with audio at $0.05/s (ai.google.dev and kling.ai, September 2026). Google lists 22 October 2026 as the earliest shutdown date for the Veo 3.1 preview models in the Gemini API (ai.google.dev, October 2026). Match the model to the shot.
Is there a cheaper alternative to Seedance?
Yes, at published rates. Kling 2.6 is $0.042/s at 720p without audio, and Veo 3.1 Lite is $0.05/s at 720p with audio, against Seedance 2.0 at $0.15/s at 720p (kling.ai, ai.google.dev and docs.byteplus.com, September 2026). Seedance 2.0 Mini is $0.08/s at 720p if you want to stay in the same family. Before switching, check your route, since buying Seedance 2.0 through Runway’s API costs 2.4x the direct rate.
What is the current version of Seedance?
ByteDance launched Seedance 2.5 on 31 July 2026, and its BytePlus API is live: 4 to 30 seconds, up to 1080p, and up to 30 images, 10 video clips and 10 audio clips as references (seed.bytedance.com, October 2026). BytePlus still sells Seedance 2.0, with Fast and Mini variants. DesignerBox carries Seedance 2.0.
Which Seedance alternative makes the longest clips?
Veo 3.1. Base clips run 4 to 8 seconds, but in the Gemini API extension adds 7 seconds at a time, up to 20 times, for a 148 second maximum at 720p (ai.google.dev, September 2026). Seedance 2.0 and Kling 3.0 reach 15 seconds in one generation, and Kling 2.6 and Runway Gen-4.5 reach 10. Sora 2 Pro extended to 120 seconds, but OpenAI removed Sora 2 and Sora 2 Pro from its API on 24 September 2026 (OpenAI API deprecations, accessed September 2026). Sora alternatives compares the longest single take of each model that replaces Sora.
Is there an open source Seedance alternative?
Partially. Alibaba’s Wan open weights on Hugging Face stop at Wan 2.2, under Apache 2.0. LTX-2.3 from Lightricks and HunyuanVideo-1.5 from Tencent both publish weights, but under community licenses with use and territory restrictions. Read the license before shipping commercial work.
Does Runway Gen-4.5 support 4K and audio?
Not as shipped, according to Runway. Its spec lists 720p output and 2 to 10 second durations, and its current spec and API list no audio output (help.runwayml.com and docs.dev.runwayml.com, September 2026). Runway announced native audio for Gen-4.5 in December 2025. 4K comes from a separate upscale step after the clip is made.
Can I run more than one video model from one account?
Yes. In DesignerBox each video model is one step in a workflow, and you pick the model for each step. An 8-second clip costs 40 to 560 credits, depending on the model, and the cost of a run is shown before it starts.
