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.

Examples

The camera slightly pulls back to reveal a full view of the street and follows the female lead as she moves. The wind flutters her skirt as she walks down a 19th-century London street. As she continues walking, a steam car drives up from the right side of the street, quickly passing by her. The wind lifts her skirt, and with a shocked expression on her face, she hurriedly uses both hands to hold it down. Background sounds include footsteps, crowd noise, car noises etc.

Fixed camera shot, a girl is elegantly hanging clothes to dry. After one piece is hung, she takes another from the bucket and gives it a vigorous shake.

$Use @ Reference Image as the main character, keeping facial features and body proportions consistent throughout. She is a 30-year-old women. Cinematic time-freeze short film, 15 seconds, ultra-realistic, shot on Arri Alexa Mini, 35mm lens, moody sports bar interior lighting with neon accents, volumetric haze, dynamic hard shadows, shallow depth of field. [0:00–0:03] A packed, dimly lit sports bar, time flowing normally. Steadicam frontal medium shot tracking her walking confidently through absolute chaos. On the blurred TVs in the background, the Yankees have just clinched the World Series. The crowd is erupting in pure euphoria. As he walks, he raises his right hand and snaps. [0:03–0:06] At the snap, a subtle spherical shockwave bursts from her fingertips with air distortion and light refraction, expanding outward. Everything freezes mid-explosion. Thick arcs of golden beer suspend in the air, with individual glistening droplets visible. Popcorn kernels float motionless. People are frozen mid-cheer and mid-air in leaping embraces. Volumetric neon light catches the suspended dust and liquid. Absolute silence. [0:06–0:09] Only she moves. her footsteps echo slightly. The camera moves backward as he walks through the frozen celebration, observing calmly. she casually ducks under an arc of frozen, splashing beer. she notices a cluster of floating popcorn, reaches out, and plucks a single kernel from the air. [0:09–0:11] sHe stops in front of a frozen women wearing a Yankees jersey, her face locked in an ecstatic, tearful scream, arms raised for a high-five. The main character tilts her head, gently adjusts the brim of the frozen women's Yankees cap, nods slightly, and softly says: “perfect.” [0:11–0:15] She turns, tosses the popcorn kernel into her mouth, and crunches it. She faces the camera, smirks, and snaps again. A stronger reverse shockwave restores motion. The beer completes its splash, the cheering roar instantly returns, and fans land their jumps. She walks away as the camera pushes through the wildly celebrating crowd. Fade to black. Sound: deafening bar roar/celebration → snap → deep shockwave/bass drop → absolute silence → footsteps → sharp popcorn crunch → “perfect” → snap → reverse shockwave → deafening celebration returns.$

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.

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.
