Model Card
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.

Dola Seedream 5.0 Flash
Dola Seedream 5.0 Flash is ByteDance's fast, lower-cost image generation and editing model in the Seedream 5.0 family, offered here through BytePlus's ModelArk API under the "Dola" branding. It supports text-to-image and reference-guided editing with up to 10 input images, local edits targeted with point and bounding-box coordinates in the prompt, transparent-background output, and decomposition of an image into separate transparent layers. Output is 1K to 2K. BytePlus positions it as "faster image creation, stronger layouts, lower cost at scale." A third-party launch-day test reported 15 to 20 seconds per text-to-image request. It is the cheapest model in the Seedream 5.0 line, and Dola Seedream 5.0 Pro remains the better choice for photorealism and fine material detail. It suits high-volume work such as ad concepts, thumbnails, social visuals, and rapid design iteration.
ChatDeepSeek V4.1 Flash
DeepSeek V4.1 Flash is a Mixture-of-Experts chat model from DeepSeek, made available here through BytePlus's ModelArk platform. It succeeds DeepSeek V4 Flash, keeps a 1 million token context window, and accepts text and image input. In DeepSeek's own tests it scored 90.6 on Terminal-Bench 2.1, ahead of Claude Opus 5 (89.1) and GPT-5.6 Sol (88.8), and 74.2 on DeepSWE v1.1 versus 74.0 for Claude Opus 5. DeepSeek also reports it outperforming the larger V4 Pro. It supports tool calling and up to 384,000 output tokens, which suits coding agents, tool-calling pipelines, and long-context workloads at $0.30 per million input tokens and $1.20 per million output tokens.
ChatGLM-5.3 Flash
GLM-5.3 Flash is a multimodal Mixture-of-Experts model from Zhipu AI (Z.ai), available here through BytePlus's hosted API. It has 320 billion total parameters with 18 billion active per token, accepts text and image input, and supports a 1 million token context window. Z.ai reports 84.3 on Terminal-Bench 2.1 and 63.4 on DeepSWE v1.1 (GLM-5.2 scored 46.2). On Terminal-Bench 2.1 that is close to Claude Opus 4.8 at 85.0. Artificial Analysis gives it 57 on its Intelligence Index, three points behind the larger GLM-5.3. It is the lower-cost model in the GLM-5.3 family and supports tool calling. It suits coding agents and multi-step automation where per-token price matters.
