Seedance 2.0 Fast Overview
Seedance 2.0 Fast is a speed-optimized variant of ByteDance's unified multimodal audio-video generation model. It accepts text, image, audio, and video inputs in combination, like Seedance 2.0, but targets shorter wall-clock times and higher throughput for iterative workflows. It produces multi-shot videos with dual-channel synchronized audio including dialogue, ambient sound, and effects, with physics-aware motion and editing controls, while prioritizing responsiveness over the last increment of visual refinement so teams can preview and ship ideas faster.
More models from ByteDance
Seedance 2.0 is a unified multimodal audio-video generation model from ByteDance that accepts text, image, audio, and video inputs in combination, supporting up to 9 images, 3 video clips, and 3 audio clips as reference. It generates multi-shot videos up to 15 seconds with dual-channel synchronized audio including dialogue, ambient sound, and effects. It features physics-aware motion, improved controllability for video extension and editing, and strong instruction following for complex scene composition.
Seedream 5.0 Lite is an advanced image generation model from ByteDance that produces high-quality still images from text prompts while providing flexibility for editing workflows. It is designed to combine expressive creativity with precise control over layout, composition, styles, and details, interpreting nuanced instructions faithfully. Users can incorporate a single reference image to guide generation or editing. Integrated search and reasoning features let the model visualize real-time trends and domain information in the output.
Seedance 1.5 Pro is a next-generation AI video model from BytePlus that generates cinematic videos with native synchronized audio directly from text or image inputs. It offers precise audio-visual timing, strong motion coherence, expressive camera control, and advanced narrative prompt handling for short video creation.
Seedream 4.5 is a ByteDance image model for precise 2K to 4K generation and editing. It improves multi image composition, preserves reference detail, and renders small text more reliably. It supports up to 14 reference images for stable characters and design heavy layouts.
ByteDance Video Upscaler boosts video resolution to 1080p, 2K, or 4K with advanced denoising and motion enhancement. It restores color, reduces compression artifacts, and improves clarity for legacy films, UGC clips, and short narrative content through a simple API.
Seedance 1.0 Pro Fast accelerates the core Seedance pipeline for expressive dance and performance clips. It turns text prompts or reference images into smooth, cinematic motion with strong temporal consistency. Ideal for rapid iteration in creative tools and production workflows.
Seedream 4.0 is ByteDance’s multimodal image model for fast 2K to 4K generation. It supports text prompts, image editing with natural language, and multi image reference. It maintains style consistency across batches and handles bilingual Chinese and English workflows.
OmniHuman-1.5 generates high fidelity avatar video from a single image with audio and optional text prompts. It fuses multimodal reasoning with diffusion motion to keep identity stable, lip sync accurate, and gestures context aware for long, multi subject clips.
Seedance 1.0 Pro is a ByteDance video model for 5 to 10 second clips at up to 1080p. It supports text prompts and image first frames. It delivers smooth motion with strong temporal consistency. Ideal for multi shot storytelling, ads, and design previews in real time pipelines.
OmniHuman-1 is a ByteDance research model for human video generation from a single image and motion signals like audio. It focuses on accurate lip sync, expressive motion, and strong generalization across portraits, full body shots, cartoons, and stylized avatars.
