Seedance 2.0 Fast (Build 260128)
The dreamina-seedance-2-0-fast-260128 API is the Dreamina-channel build of ByteDance's Seedance 2.0 Fast text-to-video model on GPTProto — the same speed-tuned motion engine as the doubao build, sourced through ByteDance's Dreamina creative line. It renders 480p–720p clips of 4–14 seconds with optional native audio and a seed for reproducibility. If you want the full Seedance 2.0 Fast model overview, see the doubao-seedance-2-0-fast-260128 page; this page focuses on what's specific to the Dreamina channel, how it compares to Doubao, and how to integrate its endpoint. One API key covers it and 200+ other models, billed pay-as-you-go from $0.2365 per clip.

Dreamina-seedance-2-0-fast-260128 API
The dreamina-seedance-2-0-fast-260128 API is the Dreamina-channel build of ByteDance's Seedance 2.0 Fast text-to-video model, live on GPTProto from $0.2365 per clip. It shares the same weights as the doubao build — so this page covers what's specific to the Dreamina route: how it differs from Doubao, the endpoint, and how to get access outside China.
Dreamina vs Doubao Seedance 2.0 Fast — Which Should You Call?
Both listings share the same Seedance 2.0 Fast weights, the same $0.2365 starting price, and the same API key — so the choice is about routing, not quality. There is no fidelity penalty either way. Call dreamina-seedance-2-0-fast-260128 if your workflow standardises on the Dreamina line, or if the Doubao channel is throttled; call doubao-seedance-2-0-fast-260128 otherwise. A practical pattern is to set one as your default and fail over to the other on rate limits, since both hit the same model.

The Dreamina Channel — BytePlus, ModelArk & Volcano Engine
ByteDance exposes Seedance through more than one surface, which is why you'll see several names in searches. The Doubao build is served via Volcano Engine (Ark), ByteDance's China-facing developer cloud. The Dreamina build is the creative-line version; internationally, ByteDance's video models are reachable through BytePlus ModelArk, its global model platform. On GPTProto you don't have to pick a cloud or region — the dreamina-seedance-2-0-fast-260128 API gives you the Dreamina route behind one unified key, so "BytePlus Seedance 2.0 API" and "BytePlus ModelArk video API" access resolves to a single model string here.
How to Integrate the dreamina-seedance-2-0-fast-260128 API (Endpoint)
Integrating the dreamina-seedance-2-0-fast-260128 API is a three-step, OpenAI-style flow. Point your client at GPTProto's base URL, authenticate with your GPTProto key, and set the model string to dreamina-seedance-2-0-fast-260128. Because this is a video model, generation is asynchronous: you submit a prompt plus parameters (aspect ratio, duration, resolution, audio, seed), receive a job ID, then poll for the finished clip URL. The exact request and response schema — including the video-generation endpoint path — is in the Quick Start and the linked API documentation on this page.
Using the dreamina-seedance-2-0-fast-260128 API Outside China
Reaching ByteDance's Seedance channels directly from outside China usually means a Chinese phone number or a regional payment method. GPTProto removes that: sign up with email and the dreamina-seedance-2-0-fast-260128 API access works immediately, in English, with pay-as-you-go billing and no regional gateway. You get the same Dreamina-route model that powers ByteDance's creative tools, plus the option to fail over to the Doubao build on the same key — useful for teams that need stable, international access to Seedance 2.0 Fast for production video.
Dreamina-Seedance-2.0-Fast FAQ
Common questions about using the Dreamina-Seedance-2.0-Fast AI video model.
What is dreamina-seedance-2-0-fast-260128?
The Dreamina-channel build of ByteDance's Seedance 2.0 Fast text-to-video model on GPTProto — same weights as the doubao build, different upstream route.
What's the difference between dreamina-seedance-2-0-fast and doubao-seedance-2-0-fast?
Same model and price; the prefix is the upstream ByteDance channel (Dreamina line vs Doubao / Volcano Engine). Output is identical.
Should I call the Dreamina or Doubao Seedance API?
Either — pick one as default and fail over to the other on rate limits. Both resolve to the same Seedance 2.0 Fast model.
Is this the same as the BytePlus / ModelArk Seedance 2.0 API?
It's the Dreamina-route Seedance 2.0 Fast model; BytePlus ModelArk is ByteDance's international platform for these video models. On GPTProto it's one model string, one key.
What is the dreamina-seedance-2-0-fast-260128 API endpoint?
You call GPTProto's video-generation endpoint with model dreamina-seedance-2-0-fast-260128, submit a job, and poll for the clip. See the Quick Start and docs.
How do I get a Dreamina Seedance 2.0 Fast API key?
Create a free GPTProto account, add credit, generate a key; it works across 200+ models. (See the steps above.)
Can I use dreamina-seedance-2-0-fast-260128 outside China?
Yes — email signup, English docs, pay-as-you-go, no Chinese phone number or regional payment needed.
What is the maximum clip length?
4–14 seconds per render; chain clips for longer sequences.
How do I optimize prompts for Dreamina-Seedance-2.0-Fast?
Focus on descriptive, short phrases. Mention specific camera movements like 'slow zoom' or 'panning shot' to get the best out of Dreamina-Seedance-2.0-Fast. Avoid overly complex descriptions that might confuse the motion engine.
