Build a product-film brief around sneaker assembly, watch details, or a hangar reveal. Seedance 2.0 examples include real clips, reusable prompts, and recorded API charges.
Four different production briefs, two API platforms, and actual recorded charges. In this test set, ModelGo charged $4.636556 against OpenRouter’s $6.073200, a 23.66% reduction with matching delivered specifications.
What Is Seedance 2.0?
ByteDance’s Seedance 2.0 is a multimodal audio-video generation model with text and image reference workflows. Camera control, motion continuity and reference-led subject retention make it relevant to product films, architectural launches and game trailers.
| Industry | Production scenario | What to evaluate |
|---|---|---|
| Footwear / product advertising | Exploded sneaker assembly film | Motion continuity, subject geometry and camera control |
| Game studios / trailer previs | Orbital drone-hangar reveal | Motion continuity, subject geometry and camera control |
| Luxury goods / product education | Mechanical watch cross-section | Motion continuity, subject geometry and camera control |
| Architecture / property marketing | Retail pavilion day-to-night launch | Motion continuity, subject geometry and camera control |
Test Method and Actual Charges
We ran four distinct briefs: two text-only and two reference-driven, using matching prompts, reference files and requested settings wherever both platforms were accessible. ModelGo costs were matched to settled billing records and OpenRouter costs come from completed responses’ usage data; the table shows model-output charges rounded to six decimals, excluding separately generated reference art.
Cost scope: these are model-call charges, not the cash outlay required to fund an account. They exclude recharge/payment processing fees, including the 5.5% recharge fee used in the separate pricing comparison; percentage differences here compare call charges only.

Four Production Examples
Exploded sneaker assembly film
Production use: Footwear / product advertising.
Exact prompt
Create a 10-second premium product film for an original graphite running shoe with a translucent blue sole. Seconds 0–3: a slow lateral dolly reveals the intact shoe on a dark studio plinth. Seconds 3–7: the outsole, cushioning layer and textile upper separate vertically into a clean exploded view, with each component retaining its shape and aligned position. Seconds 7–10: all three components settle back into the original shoe, ending on a stable hero composition with empty space on the left for copy added later. Maintain one continuous camera path, plausible materials and controlled rim lighting. No text, logos, numerical performance claims, extra shoes or chaotic particles. Emphasize assembly clarity over fast editing. Deliver one coherent ten-second clip. Avoid speed ramps, unrelated cutaways and abrupt changes in camera direction; preserve the specified subject throughout.
23.66% lower ModelGo charge.
Orbital drone-hangar reveal
Production use: Game studios / trailer previs.
Exact prompt
Create a 10-second cinematic reveal for an original science-fiction game. Begin just behind a maintenance rail inside a vast orbital hangar, with a compact triangular exploration drone in the foreground. Over seconds 0–4, the camera glides past two grounded maintenance stations and approaches the drone. During seconds 4–8, the heavy segmented hangar doors open to reveal a blue planet and a distant ring station; the drone slowly rises one meter from its platform. Finish with a two-second stable silhouette against space. Preserve the drone’s geometry, correct scale and consistent direction of light. Use restrained cyan instrument lights and warm mechanical highlights. No combat, explosions, licensed designs, text or abrupt camera cuts. Deliver one coherent ten-second clip. Avoid speed ramps, unrelated cutaways and abrupt changes in camera direction; preserve the specified subject throughout.
23.66% lower ModelGo charge.
Mechanical watch cross-section
Production use: Luxury goods / product education.

This original reference was used for ModelGo and for the paired OpenRouter request where account access was available.
Exact prompt
Animate the supplied original mechanical watch into a 10-second technical brand film. Preserve the case silhouette, brushed steel finish, dark dial and hand positions from the input. Seconds 0–3: a gentle macro push-in across the crystal. Seconds 3–7: the camera transitions through a clean semi-transparent case section to reveal three clearly connected gears turning at a slow controlled pace; the outer case remains stable. Seconds 7–10: the crystal becomes opaque again and the camera ends on the original three-quarter hero view. Use warm edge lighting, realistic metal reflections and black negative space for later editorial copy. Do not change the dial markings, add a logo, multiply gears randomly or suggest a functional engineering certification. Deliver one coherent ten-second clip. Avoid speed ramps, unrelated cutaways and abrupt changes in camera direction; preserve the specified subject throughout.
23.66% lower ModelGo charge.
Retail pavilion day-to-night launch
Production use: Architecture / property marketing.

This original reference was used for ModelGo and for the paired OpenRouter request where account access was available.
Exact prompt
Create a 10-second architectural launch film from the supplied retail pavilion image. Preserve the pavilion footprint, timber canopy, three glazed bays and surrounding planted courtyard. Begin with late-afternoon sunlight and a slow eye-level dolly along the front facade. From seconds 3–8, transition naturally through blue hour as interior lights illuminate sequentially behind the same windows and the sky darkens. Finish with two seconds of a stable warmly lit exterior, with two adult visitors walking slowly toward the entrance. Keep the architecture rigid and all reflections consistent. No additional storeys, changing window counts, signage, invented tenant logos or dramatic weather. The visual objective is a credible occupancy and lighting story. Deliver one coherent ten-second clip. Avoid speed ramps, unrelated cutaways and abrupt changes in camera direction; preserve the specified subject throughout.
23.66% lower ModelGo charge.
How to Calculate the Saving
For outputs with matching delivered specifications, calculate the reduction as (OpenRouter actual charge − ModelGo settled charge) / OpenRouter actual charge × 100. Use the returned dimensions, duration and audio track when deciding whether two outputs are comparable. Across these four briefs, the average difference was $0.359161 per output; repeating that same workload 100 or 1,000 times would mean approximately $35.916088 or $359.160882 less spend. Those are workload projections, not additional billed runs.
Start with the ModelGo API
Install requests and set MODELGO_API_KEY in your environment. The code below uses the endpoint, model ID and parameters from the first real example, with its exact prompt embedded directly. This example submits an asynchronous video job; polling and download steps are described below the code.
import os, requests
prompt = 'Create a 10-second premium product film for an original graphite running shoe with a translucent blue sole. Seconds 0–3: a slow lateral dolly reveals the intact shoe on a dark studio plinth.

headers = {"Authorization": "Bearer " + os.environ["MODELGO_API_KEY"]}
payload = {'model': 'doubao-seedance-2.0',
'prompt': prompt,
'resolution': '720p',
'duration': 10,
'aspect_ratio': '16:9',
'generate_audio': False}
response = requests.post('https://api.modelgo.ai/v1/video/generations', headers=headers, json=payload, timeout=420)
response.raise_for_status()
result = response.json()
print(result) # Save the returned task ID for polling.After submission, retain id / task_id from the response and poll GET https://api.modelgo.ai/v1/videos/{task_id} until the task reaches a terminal state. Once successful, download the video using metadata.url from the response.
For first-frame generation on the native content route, send a content array containing the text part and an image_url part with role: "first_frame".
ModelGo and OpenRouter use different model IDs and media request formats. Reuse the production brief, but adapt the endpoint, reference-image structure, task polling and download handling following each platform’s documented request format.
