ByteDance: Seedance 1.5 Pro
Going away Nov 11, 2026Seedance 1.5 Pro makes a video and its sound together in one pass, so voices, effects and ambience line up with the picture and lips match the speech. You give it a written description, optionally a still image or first and last frames, and get back 4 to 12 seconds up to Full HD. Choose it for short dialogue scenes in many languages. It takes no video or audio references; Seedance 2.0 does.
Seedance 2.0 turns a written description, still images, video clips or audio references into a video with matching sound, 4 to 15 seconds long. Give it pictures of a character and it keeps that person recognisable from shot to shot, and you can fix the first and last frame of a clip. It is the only model in the Seedance line here that goes up to 4K.
Seedance 2.0 Fast takes the same text, image, video and audio inputs as Seedance 2.0 and gives back a 4 to 15 second clip with sound, in low resolution or HD. It is built for speed, so it suits storyboards, ad drafts and testing many ideas before you commit to one. Once a description works, rerun it on Seedance 2.0 when you need Full HD or 4K delivery. Mini sits below Fast in the same line and shares its HD ceiling.
Seedance 2.0 Mini takes a written description plus image, video and audio references and gives back a 4 to 15 second clip with sound, in low resolution or HD; you can also set the first and last frame. Use it for high-volume drafting where each clip is judged quickly. For sharper pictures move to Seedance 2.0 (up to 4K); Seedance 2.0 Fast shares the same size limits but is the version tuned for speed.
Seedance 2.5 is the pick when one clip must run long: it makes up to 30 seconds in a single pass and can be extended twice more. It takes a written description plus image, video and audio references, lets you set the opening frame or both end frames, and edits existing footage, including green-screen replacement. Output stops at HD.
UI-TARS 1.5 7B takes a screenshot of a desktop, browser or phone screen plus your instruction, and replies with its reasoning and the next action, including the spot on the screen to click. Use it as the eyes of an agent that controls a computer or browser, run in a loop with one screenshot per step.
