Model Card
Seedance 1.0 Pro Fast is ByteDance's speed-optimized variant of Seedance 1.0 Pro, offered here through BytePlus's hosting. BytePlus documentation describes it as inheriting Seedance 1.0 Pro's core strengths, including deep instruction parsing, multi-shot storytelling with natural transitions, and detail rendering for faces and hair, while running about 3x faster and at roughly 72% lower output cost than the standard Pro model.
Through this API it supports 480p, 720p, and 1080p at up to 12 seconds and 24fps, the same resolution and duration range as Seedance 1.0 Pro. It fits workloads where volume and turnaround matter, such as rapid iteration and high-throughput content pipelines, with Seedance 1.0 Pro itself the better choice when quality matters more than speed.

Dola Seed 2.1 Turbo
Dola Seed 2.1 Turbo is ByteDance's faster, lower-cost variant in the Seed 2.1 family, offered internationally through BytePlus's Model Ark platform. It accepts text, image, and video input, with a 256K context window and function calling for agent workflows. On ByteDance's own benchmarks against Claude Opus 4.7, GPT-5.5, and Gemini 3.1 Pro, Turbo scores 89 on VideoMME for long video understanding and 79.2 on OVOBench for streaming video, ahead of Gemini 3.1 Pro's 86.7 and 64.1. It scores 88.0 on BeyondAIME reasoning, above Seed 2.1 Pro's 87.0. On knowledge tests like SuperGPQA it trails GPT-5.5 and Gemini. These are vendor-reported figures, not independently verified. It suits high-volume API use such as video analysis, document processing, and agent pipelines, where cost and video handling matter more than peak coding scores.
ImageDola Seedream 5.0 Pro
Dola Seedream 5.0 Pro is ByteDance's Seedream 5.0 Pro image generation and editing model, offered here through BytePlus's ModelArk API under the "Dola" branding BytePlus uses across its hosted model lineup. It generates images as independently editable layers, separating subjects, text, and background so pieces can be repositioned or swapped after generation. It supports pixel-level editing through selection points, arrows, and annotation boxes, reads color codes and material specifications, and renders text across 14 or more languages including Arabic, Korean, Thai, French, Russian, and Japanese. On Artificial Analysis's independent Text-to-Image Elo leaderboard it scores 1,283, ranking 8th overall, ahead of Black Forest Labs' FLUX.2 Max (1,233) and just behind Google's Nano Banana Pro (1,299). It fits production teams that need layered, editable output and multilingual text rather than a single flattened image.
VideoDreamina Seedance 2.5
Dreamina Seedance 2.5 is ByteDance's newest Seedance video model, distributed under the Dreamina brand and hosted here through BytePlus. It follows Seedance 2.0, extending single-pass clips from 15 seconds to 30 seconds, with support for multi-round extension beyond that. Through this API it renders at 480p, 720p, or 1080p at 24fps, dropping the 4K tier that 2.0 offered. Reference input also grows. ByteDance says it can combine up to 50 assets in one generation call, including up to 30 images, 10 video clips, and 10 audio clips alongside a text prompt, plus native audio-video generation in a single pass and timestamp-level editing for adjusting specific segments of a clip. ByteDance also reports improved texture, lighting, and motion detail over 2.0. It suits the same production use cases as the 2.0 family, such as marketing clips and multi-shot sequences, now with longer single takes and more reference material to work from.
