Bytedance AI Models: All Versions Compared
Advanced AI image generation technology from Bytedance
ByteDance is the AI video generation suite from the creator of TikTok and CapCut — delivering AI video generation through the Seedance model series built for cinematic quality, native audio, and multimodal input. From Seedance 2.0's 15-second 2K video with synchronized audio to its fast generation variants, every ByteDance model available on AI Compare Hub can be tested and compared against other leading AI video models, for free.
What you can create with ByteDance's models
-
Cinematic 2K video from text
Seedance 2.0 generates video clips up to 15 seconds at 2K resolution from text prompts alone. Describe a scene, camera movement, or narrative arc and the model produces broadcast-quality footage.
-
Video with synchronized native audio
Seedance 2.0 produces audio as part of the video output — dialogue, sound effects, and ambient atmosphere — without requiring separate audio editing or post-processing.
-
Video from image and multimodal inputs
Seedance 2.0 accepts up to 12 combined input files including text, images, video clips, and audio. Use a reference image to steer the visual style, or combine multiple asset types to guide the generation.
-
Long-form video sequences
The Seaweed sub-model within Seedance 2.0 generates sequences up to 30 seconds — significantly longer than most competitors. For shorter clips requiring complex sequential motion, the PixelDance sub-model handles 10-second scenes with precision.
-
Social and vertical content
ByteDance's Seedance models are built for TikTok and CapCut workflows, with direct integration into the CapCut editor. Fast generation variants are optimised for high-volume social content production on Reels, TikTok, and Shorts.
Why creators choose ByteDance's models
-
Native audio-visual generation Seedance 2.0
Seedance 2.0 generates video and audio together from a single prompt — one of the few models to do so natively. Describe the dialogue, music, or sound environment in your prompt and it arrives in the output alongside the video.
-
12-file multimodal input
Seedance 2.0 accepts more input types simultaneously than most competing models — up to 12 combined text, image, video, and audio files. This makes it uniquely suited to briefs where the output must match existing visual assets or audio references.
-
Dual sub-model architecture
Seedance 2.0 uses two specialised sub-models: PixelDance for complex, precisely sequenced 10-second clips, and Seaweed for longer narratives up to 30 seconds. The right engine is selected automatically based on your generation type and prompt.
-
Up to 30-second video output
While most AI video models top out at 10–15 seconds, Seedance 2.0's Seaweed architecture produces clips up to 30 seconds — giving creators enough runtime for short ads, social videos, and narrative sequences in a single generation pass.
-
TikTok and CapCut ecosystem integration
ByteDance's Seedance models are deeply embedded in CapCut and Jianying — platforms used by hundreds of millions of creators globally. Generating with Seedance on AI Compare Hub lets you evaluate the same underlying models powering the world's largest short-video editing ecosystem.

Common questions
What AI models does ByteDance offer on AI Compare Hub?
ByteDance's model family on AI Compare Hub centres on the Seedance series, including Seedance 2.0 — the flagship model with 2K resolution, native audio, and multimodal input support. Seedance 2.0 incorporates two specialised sub-models: PixelDance for complex motion sequences up to 10 seconds, and Seaweed for longer sequences up to 30 seconds.
What is the difference between Seedance 2.0 and earlier Seedance versions?
Seedance 2.0 (launched February 2026) introduced native audio generation, multimodal input support for up to 12 files, 2K resolution output, and the dual sub-model architecture combining PixelDance and Seaweed. Earlier Seedance versions did not include native audio or the expanded multimodal input pipeline.
Does Seedance support audio generation?
Yes — Seedance 2.0 generates audio natively as part of the video output. Include descriptions of dialogue, sound effects, music, or ambient atmosphere in your text prompt and Seedance 2.0 produces the audio alongside the video in a single generation pass.
Which ByteDance model is best for AI video generation?
Seedance 2.0 is ByteDance's highest-capability model — recommended for any use case requiring cinematic quality, native audio, long-form video up to 30 seconds, or multimodal reference inputs. For rapid iteration and high-volume social content where speed matters more than maximum quality, fast generation variants offer significantly reduced generation time.
How long can videos generated by ByteDance's models be?
Seedance 2.0 supports video generation up to 15 seconds via the standard PixelDance path, with the Seaweed sub-model enabling sequences up to 30 seconds for longer narrative content. This puts Seedance 2.0 among the longest-output AI video models available today.
