SeeDance 2.0 vs Kling 3.0: API Comparison and Pricing (2026)

SeeDance 2.0 (ByteDance) and Kling 3.0 (Kuaishou) are the two flagship Chinese video models worth shortlisting in May 2026. They overlap on a lot. Both produce native synchronized audio, both do multi-shot narrative output in a single call, both target 4 to 15 second videos. They split sharply on the rest. Multimodal omni-reference is SeeDance's lane. A per-second cost floor below $0.05 is Kling's.

TL;DR: Pick SeeDance 2.0 when the prompt is reference-heavy: nine images, three videos, and three audio tracks per call addressable by @Image1 / @Video1 / @Audio1 placeholders. Pick Kling 3.0 for the lowest per-second cost ($0.05–0.063 starting) or multi-language lip-sync across English, Chinese, Japanese, Korean, and Spanish. Both reach 4K: SeeDance 2.0 on Pro, Kling 3.0 on Ultra. Both deliver multi-shot narrative output and native audio in the same generate call. Live rates: pricing page.

SeeDance 2.0 vs Kling 3.0 at a glance

What SeeDance 2.0 is

SeeDance 2.0 is ByteDance's February 2026 video model. It introduces multimodal omni-reference to the SeeDance line. A single generate call accepts a prompt plus up to nine reference images, three reference videos, and three reference audio tracks, all addressable in the prompt with placeholders like @Image1, @Video1, and @Audio1. The model also generates synchronized audio in the same pass, with millisecond lip-sync across multiple languages.

The other big shift is multi-shot storytelling. SeeDance 2.0 can render multiple shots in one call while keeping the same character recognisable across them. Combined with the 15-second max single-video duration, that makes it strong for short narrative arcs.

What Kling 3.0 is

Kling 3.0 is Kuaishou's February 2026 flagship. It steps Kling up from "fast and cheap" to a proper flagship. Three things define it: 4K output on the Ultra variant, multi-shot mode (2 to 6 connected scenes in one call with shared character consistency), and Audio 2.0 with multi-language lip-sync across English, Chinese, Japanese, Korean, and Spanish.

The other interesting piece is the Visual Chain-of-Thought reasoning Kuaishou added in 3.0. It is a planning step before generation that produces stronger scene composition on complex prompts than 2.6 ever did.

Where each model wins

SeeDance 2.0 wins on

• Multimodal references in one call. Nine images, three videos, three audio tracks, addressable by name in the prompt. Kling 3.0's Elements 3.0 caps at four reference images plus a video lock.
• Aspect-ratio coverage. 1:1, 4:3, 16:9, 9:16. Kling 3.0 supports 1:1, 16:9, 9:16 (no 4:3).
• Audio matching from reference. Pass an audio track in the omni-reference set and the model tries to match its mood and style. Kling 3.0 generates audio but does not accept reference audio as an input.
• Cinematic camera controls as named parameters (push, pull, pan, tilt, orbit) instead of relying on prompt language alone.

Kling 3.0 wins on

• Per-second cost. Starts at $0.05–0.063 per second vs SeeDance 2.0 Fast at $0.11/s and Pro from $0.13/s. For a 10-second video, that is $0.50–0.63 vs $1.10 (Fast) or from $1.30 (Pro).
• Multi-language lip-sync. Audio 2.0 is tuned across five languages with phoneme alignment. SeeDance also does multi-language lip-sync, but Kling 3.0 documents the language list directly.
• Visual Chain-of-Thought reasoning. Plans the scene before generating. Useful for prompts with complex spatial relationships.
• Variant ladder for 4K delivery. Standard for drafts, Pro for paid placements, Ultra for 4K hero work, with no separate upscale step.

Pricing math: side-by-side

The two models price per second, so the comparison normalises cleanly. Numbers below were accurate at the time of writing; check the pricing page for live rates.

Read: Kling 3.0 is the cheaper option per second across the board; both reach 4K (SeeDance 2.0 on Pro, Kling 3.0 on Ultra). SeeDance 2.0 wins when the prompt actually exercises the omni-reference surface. Nine-image multi-asset compositions with audio matching are not a Kling 3.0 workflow.

When to pick SeeDance 2.0

• Your prompt references multiple assets (images, source videos, audio mood) and you want to wire them in by name (@Image1, @Video1, @Audio1).
• You need 1:1 or 4:3 as a first-class aspect ratio.
• You want named cinematic camera controls (push, pull, pan, tilt, orbit) rather than prompt-only camera direction.
• You're producing character-driven content where the audio mood matters as much as the visual.

When to pick Kling 3.0

• You need 4K output at the lowest per-second cost.
• Per-second cost matters and you want the lowest list price among the flagship Chinese video models.
• Your delivery targets multi-language audiences (English, Chinese, Japanese, Korean, Spanish) and you want clean lip-sync per language.
• You're producing 3 to 6 connected scenes with consistent characters where 4K Ultra delivery is the goal.
• You want the Standard / Pro / Ultra variant ladder built into the same model.

Code: calling each model on Unifically

Both use the same async pattern: POST a generation, poll the task endpoint, fetch the MP4.

SeeDance 2.0 Pro (omni-reference, multi-shot)

const API = 'https://api.unifically.com';
const headers = {
  Authorization: `Bearer ${process.env.UNIFICALLY_API_KEY}`,
  'Content-Type': 'application/json',
};

const start = await fetch(`${API}/v1/tasks`, {
  method: 'POST',
  headers,
  body: JSON.stringify({
    model: 'bytedance/seedance-2.0-pro',
    input: {
      prompt:
        'Shot 1: a chef in @Image1 plates the dish from @Image2. Shot 2: she walks the plate to the dining room. Soundtrack matches the mood of @Audio1.',
      aspect_ratio: '16:9',
      duration: 15,
      images: ['https://example.com/chef.jpg', 'https://example.com/dish.jpg'],
      audio: ['https://example.com/jazz-mood.mp3'],
    },
  }),
}).then((r) => r.json());

Kling 3.0 Pro (multi-shot, 1080p)

const start = await fetch(`${API}/v1/tasks`, {
  method: 'POST',
  headers,
  body: JSON.stringify({
    model: 'kuaishou/kling-3.0-video',
    input: {
      mode: 'multi_shot',
      duration: 15,
      aspect_ratio: '16:9',
      quality: 'pro',
      shots: [
        { prompt: 'Establishing shot: a chef walks into a sunlit kitchen', duration: 5 },
        { prompt: 'Medium shot: she plates the dish with deliberate care', duration: 5 },
        { prompt: 'Close-up: she serves it to a guest, who smiles', duration: 5 },
      ],
    },
  }),
}).then((r) => r.json());

Polling is identical. /v1/tasks/{task_id} is the same endpoint for every Unifically model.

Things to watch for

• Asking SeeDance 2.0 Fast for 4K. 1080p and 4K are Pro-only resolutions on Unifically; Fast caps at 720p. Draft on Fast, re-render the keeper on Pro at 4K.
• Treating Kling 3.0 Elements 3.0 like SeeDance 2.0 omni-reference. Elements caps at four reference images plus a video lock. SeeDance 2.0 takes nine images, three videos, and three audio tracks per call.
• Defaulting to Pro on every iteration. Both expose lower variants (SeeDance 2.0 Fast, Kling 3.0 Standard) for drafting cheaply. Promote to Pro / Ultra only after a result survives review.
• Using 4:3 prompts on Kling 3.0. Kling 3.0 supports 16:9, 9:16, and 1:1. For 4:3, SeeDance 2.0 is the better choice.
• Comparing Kling 2.6 prices to Kling 3.0. Kling 2.6 prices at $0.03 per second on Unifically. 3.0 starts at $0.05–0.063 per second. They are different products at different price points.

Frequently asked questions

What is the main difference between SeeDance 2.0 and Kling 3.0?

SeeDance 2.0 wins on multimodal omni-reference: nine images, three videos, three audio tracks per call, addressable by name in the prompt. Kling 3.0 wins on per-second cost ($0.05–0.063 starting) and multi-language lip-sync across five languages; both reach 4K.

Which is cheaper, SeeDance 2.0 or Kling 3.0?

Kling 3.0 is cheaper per second across every variant. Kling 3.0 starts at $0.05–0.063 per second on Unifically. SeeDance 2.0 Fast is $0.11 per second; Pro starts from $0.13 per second. For a 10-second video, that is roughly $0.50–0.63 on Kling 3.0 vs $1.10 (SeeDance Fast) or from $1.30 (SeeDance Pro).

Does Kling 3.0 support 4K?

Yes, on the Ultra variant. SeeDance 2.0 also reaches 4K on its Pro variant through Unifically, so resolution alone no longer decides between them; compare per-second cost and how reference-heavy the prompt is instead.

Can both models do multi-shot output?

Yes. SeeDance 2.0 generates multi-shot narrative with character consistency across scenes. Kling 3.0 multi-shot mode renders 2 to 6 connected scenes in one call totalling 3 to 15 seconds. Both keep the same character recognisable across shots in a single generate.

Which model should I pick for a 15-second multi-shot ad with multiple reference assets?

If the references are mostly images (≤ 4) and per-second cost matters, pick Kling 3.0 Ultra with Elements 3.0. If the references span multiple images plus a source video plus a target audio mood, pick SeeDance 2.0 Pro. The omni-reference surface is the differentiator.
