Seedance 2.0 Fast from ByteDance and the Kling 3.0 line from Kuaishou share one trait: you pick the output tier by picking the model id, and the request carries no resolution field. Seedance 2.0 Fast and Kling 3.0 Standard both sit at 720p, so they are the closest pair. Fast accepts more inputs, while Kling 3.0 reaches 1080p and 4k through its Pro and 4K variants. Both always return audio. The comparison covers catalog facts and prices, not output quality.

Why compare Kling 3.0 with Seedance 2.0 Fast?

Kling 3.0 and Seedance 2.0 Fast requests look alike, because neither takes a resolution field. A fixed-tier model has no resolution to tune and no default to forget, and the price per second depends only on the model id. That makes Seedance 2.0 Fast and Kling 3.0 Standard drop-in alternatives at 720p for many text-to-video and image-to-video requests, as long as the other fields fit both.

Which Kling 3.0 variant matches Seedance 2.0 Fast at 720p?

Kling 3.0 Standard and Seedance 2.0 Fast. A text-to-video request at 16:9, 9:16 or 1:1, 4 to 15 seconds long and under 2,500 characters, runs on either by changing the model id. An image-to-video request moves too, provided it sends no aspect_ratio when it goes to Kling 3.0 and uses a JPEG or PNG start image, since Kling 3.0 does not read WebP.

What happens if you send resolution to Kling 3.0 or Seedance 2.0 Fast?

Kling 3.0 and Seedance 2.0 Fast both return a validation error before any job is created. The error points at the resolution field with the message "has a fixed resolution" after the model id, and nothing is charged because nothing ran. Remove the field, or switch to a model with tiers: Seedance 2.0 offers 720p and 1080p on one id, and Seedance 2.0 Fast vs Seedance 2.0 compares it with Fast.

Where does Seedance 2.0 Fast accept inputs that Kling 3.0 does not?

Seedance 2.0 Fast accepts four kinds of input that Kling 3.0 rejects:

  • Reference-to-video with 1 to 9 images, framed at 16:9, 9:16, 4:3 or 3:4.
  • aspect_ratio in image-to-video (six values) and in first and last frame (adaptive plus the same six).
  • 21:9, 4:3 and 3:4 in text-to-video.
  • Prompts between 2,501 and 4,000 characters.

Kling 3.0 keeps two things Fast lacks: a 3 second minimum duration and, on its Pro and 4K variants, fixed tiers above 720p.
