Short answer: pick Kling 3.0 when you want a cheap, short clip with native sound, or a planned sequence of shots in one render. Pick Seedance 2.0 when you need to steer the video with many references (up to 9 images, 3 videos and 3 audio clips), a wide or cinematic aspect ratio, or a long prompt. On AgentReel a 5-second 720p clip with sound costs 25 credits on Kling 3.0 (std) and 52 credits on Seedance 2.0.
Both models sit behind the same prompt box in AgentReel, and both run through the Kie.ai API. This comparison uses the parameters in the Kie API documentation and the prices AgentReel charges today. It does not use a benchmark score, because no neutral benchmark covers both models with the same prompts.

What Seedance 2.0 does best

Reference-driven video
Seedance 2.0 has three input modes, and they do not mix: first frame, first and last frame, or multimodal reference. The reference mode takes up to 9 images, 3 videos (2 to 15 seconds each, 15 seconds in total) and 3 audio clips. You describe in the prompt how each reference should appear. This makes it the stronger choice when a brand asset, a product shot and a voice line must all land in the same clip.
The Kie docs also note a useful trick. If you need a reference to act as the first or last frame, you can say so in the prompt. If the frames must match exactly, use the first-and-last-frame mode instead.
Long prompts and wide frames
The prompt can hold 20,000 characters. That is enough for a full shot list with timing, camera notes and dialogue. Seedance 2.0 also offers 21:9 and 4:3, which Kling 3.0 does not. With a start image, AgentReel sets the ratio to adaptive, so the clip follows the picture.
Where it costs more
Seedance 2.0 bills per second, and the rate climbs fast with resolution. On AgentReel, 5 seconds costs 24 credits at 480p, 52 at 720p and 128 at 1080p. A 15-second 1080p clip costs 383 credits. Draft at 480p, then render the keeper at a higher resolution.

Multi-shot sequences
Kling 3.0 can render several shots in one task. Set multi_shots to true and give each shot its own prompt (up to 500 characters) and duration (1 to 12 seconds). The total stays between 3 and 15 seconds. In multi-shot mode only the first frame image is used. This is the faster path to a cut sequence, such as wide shot, close-up, reaction, without stitching clips by hand.
Elements with @names
Kling 3.0 lets you define up to 3 elements and call them in the prompt with @element_name. An image element takes 2 to 4 pictures of the same subject. A video element takes one 3 to 8 second clip, and an audio element takes 5 to 30 seconds of sound. Each @element uses 37 characters of the 2,500-character prompt.
Cheap sound
Sound is optional on Kling 3.0. On AgentReel a 5-second std clip costs 18 credits silent and 25 with sound. In pro mode (1080p) the same clip costs 23 or 34 credits. That makes Kling 3.0 the cheaper way to test an idea with audio.
Price per clip on AgentReel
| Clip | Seedance 2.0 | Kling 3.0 std | Kling 3.0 pro |

| 5 s, with sound | 52 (720p) | 25 | 34 |
| 10 s, with sound | 103 (720p) | 50 | 68 |
| 15 s, with sound | 154 (720p) | 75 | 102 |
