- bytedance/seedance-2.0-fast-i2v: [Core Function] Seedance 2.0 Fast I2V is a high-speed multimodal video generation model. [Strengths] Fast generation with the multimodal and multi-shot capabilities of the Seedance 2.0 architecture. [Best For] Highly recommended for: rapid prototyping and quick multi-shot video creation. [Limitations] Do NOT use this model for the absolute highest cinematic fidelity (use the standard 2.0 model instead). [Routing] Choose this model when the user emphasizes ‘fast’ or ‘quick’ generation.
- bytedance/seedance-2.0-i2v: [Core Function] Seedance 2.0 I2V is ByteDance’s flagship unified multimodal video generation model. [Strengths] It supports complex mixed references (multiple images, audio clips) and generates up to 15s of multi-shot audio-video output with dual-channel audio. [Best For] Highly recommended for: high-end complex video generation, multi-shot narratives, and mixed-reference cinematic production. [Limitations] Do NOT use this model if you only need a very basic legacy generation without complex references. [Routing] Use this model by default for any complex, multi-reference, or high-fidelity image-to-video tasks.
- bytedance/seedance-2.0-v2v: [Core Function] Seedance 2.0 V2V is ByteDance’s flagship multimodal video-to-video model. [Strengths] It allows powerful editing and stylization of input videos by supporting mixed references (text, images, video, and audio) and producing multi-shot 15s outputs. [Best For] Highly recommended for: complex video-to-video transformations, restyling existing footage, and creating dynamic multi-shot edits. [Limitations] Do NOT use this model for simple still-image generation (use Seedream instead). [Routing] Use this model by default for any video editing or video-to-video generation tasks.
- bytedance/seedance-2.0-fast-t2v: [Core Function] Seedance 2.0 Fast T2V is the faster text-to-video variant. [Strengths] Supports 480p/720p, 24 fps, 4-15s MP4 output. [Routing] Use when speed is preferred over maximum resolution.
- bytedance/seedance-2.0-mini-t2v: [Core Function] Seedance 2.0 Mini T2V is the lightweight text-to-video variant. [Strengths] Supports 480p/720p, 24 fps, 4-15s MP4 output. [Routing] Use for cost-efficient text-to-video.
- bytedance/seedance-2.0-t2v: [Core Function] Seedance 2.0 T2V is ByteDance Dreamina Seedance 2.0 text-to-video. [Strengths] Supports 480p/720p/1080p/4k, 24 fps, 4-15s MP4 output. Text-only input — do not pass images, video, or audio. [Routing] Use for high-fidelity text-to-video when quality or 4k output is requested.
- bytedance/seedance-2.0-mini-i2v: [Core Function] Seedance 2.0 Mini I2V is the lightweight multimodal image-to-video variant. [Strengths] Supports 480p/720p, 24 fps, 4-15s MP4 output, with optional first/last frame, reference images, and audio references. [Routing] Use for cost-efficient image-to-video.
- bytedance/seedance-2.0-mini-v2v: [Core Function] Seedance 2.0 Mini V2V is the lightweight video-to-video variant. [Strengths] Supports 480p/720p, 24 fps, 4-15s MP4 output, with required reference video and optional text/image/audio references. [Routing] Use for cost-efficient video-to-video transformations.
- bytedance/seedance-2.5-t2v: [Core Function] Seedance 2.5 T2V is ByteDance Dreamina Seedance 2.5 text-to-video generation. [Strengths] It generates longer clips up to 30 seconds at 480p/720p/1080p with optional mp4 or mov output and native audio generation. [Best For] Highly recommended for: longer-form text-to-video storytelling, social clips beyond 15 seconds, and Seedance workflows that need mov output. [Limitations] Do NOT use this model if the user provides images, video, or audio as inputs. Do NOT use this model when the user requires 4k output. [Routing] Prefer Seedance 2.5 T2V when the user needs more than 15 seconds of text-to-video. Use Seedance 2.0 T2V when 4k is required. Use Seedance 2.5 I2V or V2V when media inputs are provided.
- bytedance/seedance-2.5-i2v: [Core Function] Seedance 2.5 I2V is ByteDance Dreamina Seedance 2.5 image-to-video generation supporting first-frame, first-and-last-frame, and reference-image modes. [Strengths] It supports up to 30 reference images, optional reference audio, 480p/720p/1080p, 4-30 second duration, and mp4 or mov output. [Best For] Highly recommended for: animating a keyframe, first-to-last transitions, multi-image character consistency, and image-led storytelling on Seedance 2.5. [Limitations] Do NOT mix first_frame_image or last_frame_image with reference_images. Do NOT send video_urls on I2V. Do NOT use audio_urls alone. Do NOT use this model when the user requires 4k output. [Routing] Prefer this model for Seedance 2.5 image-driven generation. Use Seedance 2.5 T2V for text-only requests and Seedance 2.5 V2V when reference video is required.
- bytedance/seedance-2.5-v2v: [Core Function] Seedance 2.5 V2V is ByteDance Dreamina Seedance 2.5 video-to-video generation covering multimodal reference, video editing, and video extension. [Strengths] It accepts up to 10 reference videos, 30 reference images, and 10 audio clips, with 480p/720p/1080p, 4-30 second output, and mp4 or mov containers. [Best For] Highly recommended for: editing existing clips, extending motion from a base video, multi-reference restyling, and prompt-driven composition that cites @Video1 or @Image1. [Limitations] Do NOT use this model for text-only or first-frame-only workflows. video_urls is required. Do NOT send first_frame_image or last_frame_image. Do NOT use this model when the user requires 4k output. Do NOT use this model for audio-only input. [Routing] Prefer this model for Seedance 2.5 edit, extension, and video-reference jobs. Use Seedance 2.5 T2V for text-only and Seedance 2.5 I2V for image-first generation.
