Seedance 2.0 Mini在ModelGo：四组真实API测试，费用降低15.0%

四组不同的生产需求、两个API平台，以及实际费用记录。本组测试中，ModelGo合计费用为$2.582386，OpenRouter为$3.036600；在实际交付规格一致的条件下，ModelGo费用低14.96%。

Seedance 2.0 Mini是什么？

Seedance 2.0 Mini支持短视频文生视频和首帧驱动视频。本组测试重点观察材质运动、风格化环境变化，以及镜头路径明确的产品交互。

测试方法与实际费用

本次测试包含四组独立需求：两组纯文字生成、两组参考图生成；在双平台可访问时，使用相同Prompt、参考文件和请求设置。ModelGo费用来自逐条匹配的已结算账单，OpenRouter费用来自已完成响应中的用量费用；表格展示模型输出费用，保留六位小数，不包含单独生成参考图的费用。

费用口径：本文比较模型调用费用，不是为账户充值所需的实际支出；不包含充值或支付手续费，包括另一篇价格对比文章计入的5.5%充值费。本文费用差额及比例仅按调用费用计算。

四个真实生产案例

为准确复现真实调用，本节保留当时提交的英文Prompt原文；中文说明用于解释生产目标。

机织面料动态展示

应用行业：纺织/材料营销。

用十秒短片展示机织面料的材质运动，重点检查织物纹理保持、动作连续性和受控镜头；具体时间节点以实际Prompt为准。

实际提交的英文Prompt

Create a 10-second macro material film for a fictional technical textile supplier. Start with a charcoal woven fabric stretched over a low sculptural ridge, its fine weave illuminated by a raking side light. Seconds 0–4: the camera slides slowly across the ridge, revealing fiber texture. Seconds 4–7: three small water droplets land on the surface, retain distinct rounded shapes and roll along the slope without merging into a flood. Seconds 7–10: the camera settles on a wide textile composition with a quiet left third for later copy. Maintain consistent weave scale and realistic surface tension. No labels, certification icons, quantified waterproof claims, impossible elastic movement or aggressive splash effects. Deliver one coherent ten-second clip. Avoid speed ramps, unrelated cutaways and abrupt changes in camera direction; preserve the specified subject throughout.

四季浮岛游戏预告

应用行业：手游/季节活动。

用浮岛游戏环境展示季节变化，观察场景结构、风格连续性和镜头控制，避免通过无关切镜掩盖环境漂移。

实际提交的英文Prompt

Create a 10-second stylized trailer shot of an original floating island with a small windmill, three cottages and a winding stone path. Hold a slow, coherent clockwise camera arc throughout. Seconds 0–3 show late-summer grass; seconds 3–7 bring a gentle wave of autumn color across the trees and fields, while the buildings and path remain exactly in place. Seconds 7–10 reveal warm window lights and a few leaves drifting past the lens. Use polished tactile miniature materials, readable silhouettes and a calm golden-hour palette. Leave open sky above the island for a title added later. No licensed characters, text, additional islands suddenly appearing or terrain morphing into different buildings. Deliver one coherent ten-second clip. Avoid speed ramps, unrelated cutaways and abrupt changes in camera direction; preserve the specified subject throughout.

会议胸卡签到演示

应用行业：活动/流程演示。

以会议胸卡参考图制作签到交互演示，重点观察物件身份、手部操作与流程可读性；具体动作顺序见真实Prompt。

这张原创参考图用于ModelGo；对OpenRouter可访问的模型，对照请求也使用同一文件。

实际提交的英文Prompt

Animate the supplied fictional event kiosk into a 10-second workflow demonstration. Preserve the kiosk enclosure, scanner position, screen layout and green accent color. Seconds 0–3: a natural adult hand brings a generic unbranded badge toward the scanner. Seconds 3–6: a subtle green light acknowledges the scan and the existing screen changes to one simple checkmark, keeping the surrounding layout stable. Seconds 6–10: the hand withdraws and a small paper badge emerges from the lower slot while the camera makes a gentle forward move. Use a realistic convention-lobby background with softly blurred visitors. No personal names, QR codes, extra fingers, fake processing-time claims or invented customer logos. Deliver one coherent ten-second clip. Avoid speed ramps, unrelated cutaways and abrupt changes in camera direction; preserve the specified subject throughout.

吊坠光影广告

应用行业：珠宝/社交广告。

依据原创吊坠制作光影广告，检查饰品结构、材质和光线变化过程中主体是否保持一致。

这张原创参考图用于ModelGo；对OpenRouter可访问的模型，对照请求也使用同一文件。

实际提交的英文Prompt

Create a 10-second square jewelry campaign film using the supplied original sculptural pendant. Preserve its asymmetric silver loop, central amber insert and chain attachment. Begin with the pendant resting on pale limestone. Over seconds 0–5, a narrow stripe of afternoon light travels across the surface as the camera makes a small lateral slide, revealing brushed metal and amber translucency. During seconds 5–8, the chain is gently tensioned from outside the frame, lifting the pendant a few centimeters with physically plausible gravity. End with a stable close-up and negative space above. Do not spin the pendant through a full orbit, add gemstones, alter its shape, show hands or add text. Deliver one coherent ten-second clip. Avoid speed ramps, unrelated cutaways and abrupt changes in camera direction; preserve the specified subject throughout.

如何计算费用差额

对于实际交付规格一致的输出，费用降低比例的计算方式为(OpenRouter 实际费用 − ModelGo 已结算费用) / OpenRouter 实际费用 × 100。判断两次输出是否可比时，应检查实际返回的尺寸、时长和音轨。这四组需求的平均单次费用差为$0.113554；如果按同样工作负载重复100或1,000次，费用差约为$11.355353或$113.553529。这只是按本次实测推算的用量示例，不是新增实际账单。

开始使用ModelGo API

先安装requests并设置环境变量MODELGO_API_KEY。以下代码使用首个真实案例的端点、模型ID和参数，已在代码中直接写入实际Prompt。此示例提交异步视频任务，后续轮询及下载方式见代码下方。

import os, requests

prompt = 'Create a 10-second macro material film for a fictional technical textile supplier.

headers = {"Authorization": "Bearer " + os.environ["MODELGO_API_KEY"]}
payload = {'model': 'doubao-seedance-2.0-mini',
 'prompt': prompt,
 'resolution': '720p',
 'duration': 10,
 'aspect_ratio': '16:9',
 'generate_audio': False}
response = requests.post('https://api.modelgo.ai/v1/content_generation/tasks', headers=headers, json=payload, timeout=420)
response.raise_for_status()
result = response.json()
print(result)  # Save the returned task ID for polling.

提交后保存响应中的id / task_id，通过GET https://api.modelgo.ai/v1/content_generation/tasks/{task_id}轮询至成功或失败状态；成功后使用响应中的content.video_url下载视频。

原生content端点的首帧生成请求使用content数组，其中包含文字部分，以及带有role: "first_frame"的image_url部分。

ModelGo与OpenRouter的模型ID和媒体请求格式存在差异。可以复用创作需求，接入时请根据各平台文档调整端点、参考图结构、任务轮询和下载处理。
