Seedance 2.5

Seedance 1.5 Pro is an advanced, joint audio-video AI generation model from ByteDance Seed, designed to create high-fidelity, cinematic, 4–12 second clips with synchronized audio, dialogue, and sound effects in a single pass. Utilizing a dual-branch diffusion transformer (DB-DiT), it specializes in realistic human motion, emotional nuance, and precise lip-sync for storytelling, advertising, and short-form content.

bytedance/seedance-2 is ByteDance’s next-generation multimodal AI video generation model for creating cinematic videos from text, images, video, and audio. It focuses on high motion quality, strong prompt adherence, realistic physics, and improved visual consistency, making it well-suited for professional video creation, storyboarding, and controllable multimedia generation.

bytedance/seedance-2-fast is the fast-generation variant of ByteDance’s Seedance 2 video model. It’s designed to produce high-quality AI videos more quickly than the standard Seedance 2 model, making it a good fit for rapid iteration, prompt testing, and scalable content workflows.

Seedance 2 Mini (often branded as Dreamina Seedance 2.0 Mini on BytePlus ModelArk) is a low-cost, fast text-to-video and image-to-video generation model that produces short 480p or 720p clips with optional native audio. It is designed for rapid iteration and everyday production workflows where speed and cost efficiency matter more than maximum resolution or fidelity.

Seedance 1.0 Pro is the full version of the Seedance model (ByteDance) with professional-level capabilities. Like the Lite version, it creates 1080p multi-shot videos from text or images, but with enhanced storytelling features. Pro supports wide dynamic motion ranges for smooth large-scale movements and native multi-shot consistency (stable subjects and style across cuts). It also interprets diverse visual styles accurately. In benchmarks, Seedance Pro shows very high prompt adherence, motion quality, and aesthetic scores. It's intended for creating polished, multi-scene videos in applications like advertising or short films.

Seedream 4.0 is a next-generation AI image generation and editing model developed by ByteDance Seed, unifying text-to-image synthesis, image editing, and multi-image composition in a single architecture for high-resolution outputs up to 4K. It excels in emotional intelligence, atmospheric rendering, character consistency, and fast inference (as quick as 1.8 seconds per 2K image), supporting resolutions like 2048×2048, 1920×1080, and custom ratios.

Seedream 4.5 is ByteDance Seed’s advanced AI image generation model for creating high-quality visuals with strong prompt adherence, excellent character consistency, and precise image editing. It supports text-to-image, image-to-image, reference-based generation, and multi-image workflows, making it useful for posters, product shots, brand visuals, illustrations, and cinematic-style imagery. It’s especially known for clear typography and readable small text, with output up to 4K resolution and strong preservation of details from reference images.

Seedream 5.0 Lite is ByteDance's fast, cost-efficient image-generation model from the Seedream family, built on a unified generation-editing architecture that runs text-to-image, single-image editing, multi-image fusion, and batch sequence generation through one endpoint. It supports up to 6 images per batch, reference-image fusion (image_urls), and configurable resolution up to 3K, trading some fidelity versus Seedream 5.0 Pro for faster, cheaper generation.
