What do Happy Horse 1.1 and Kling 3.0 share?

Happy Horse 1.1 and Kling 3.0 share a 3 to 15 second duration with a default of 5, a 2,500 character prompt cap, text-to-video and image-to-video, a 720p tier and a 1080p tier, and the 9:16, 16:9 and 1:1 ratios in text-to-video. A plain text-to-video request inside those bounds, or an image-to-video request with a JPEG or PNG start image, runs on both after a change of model id and, for 1080p, of the resolution field.

Model pages: Happy Horse 1.1, Kling 3.0 Standard, Kling 3.0 Pro and Kling 3.0 4K.

Does Happy Horse 1.1 or Kling 3.0 have first and last frame?

Kling 3.0 Pro and Kling 3.0 Standard do, and Happy Horse 1.1 does not. The two Kling 3.0 variants take a start image as image_url and an end image as last_image_url and generate the motion between them. Happy Horse 1.1 rejects mode flf, so a shot defined by its first and last frames needs Kling 3.0 or another model with that mode, such as Wan 3.0.

Which reads reference images, Happy Horse 1.1 or Kling 3.0?

Happy Horse 1.1, with up to 9 images in reference-to-video. Each reference image needs a short side of at least 400 pixels, and the mode takes no aspect_ratio field. Kling 3.0 has no reference-to-video on any variant; Kling 4.0 adds it with up to 10 images.
