MiniMax H3双平台实测：ModelGo vs OpenRouter的效果、规格与费用

把MiniMax H3用于真实制作需求，会得到什么结果？我们在ModelGo测试了四种独立工作流，已结算费用合计$3.011765；下文展示实际输出、Prompt和接入方式，同时展示已取得的OpenRouter对照，并明确标注交付规格差异。

MiniMax H3是什么？

MiniMax H3支持结合文字、图像、视频及音频语境进行多模态创作，并能生成原生音视频。本组案例重点观察服装细节、产品结构、手部交互和装置运动，实际交付规格逐项列出。

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。

前两条ModelGo任务于2026年10月30日提交，并于11月4日取回；其余ModelGo任务和全部OpenRouter对照均于11月4日生成。

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。

高级定制服装细节短片

应用行业：时尚/品牌广告。

用十秒镜头沿深灰大衣的肩线与翻领移动，展示羊毛质感，再由成人手扣上一颗纽扣，最后拉回半身人像；保持人物、衣物结构和纽扣数量一致。

实际提交的英文Prompt

Create a 10-second luxury fashion detail film with an adult model wearing a charcoal tailored coat. Begin close on the shoulder seam and lapel with soft window light, shallow depth of field and visible wool texture. Seconds 0–4: the camera tracks slowly along the lapel as the model turns only slightly. Seconds 4–7: one natural hand fastens a single large dark button without obscuring the coat construction. Seconds 7–10: pull back to a waist-up three-quarter portrait against a warm-gray studio wall. Keep the same face, coat geometry, button count and fabric texture throughout. No text, brand marks, extra fingers, instant outfit changes or exaggerated wind. If sound is generated, use only subtle cloth movement and quiet room ambience. Deliver one coherent ten-second clip. Avoid speed ramps, unrelated cutaways and abrupt changes in camera direction; preserve the specified subject throughout.

输出规格存在差异，不作同规格节省结论。

实际返回的输出规格存在差异。在根据费用差额选择平台前，请先核对展示的尺寸和音轨。

骑行头盔气流可视化

应用行业：运动装备/产品广告。

制作骑行头盔的气流可视化广告，重点观察通风结构、头盔几何和可视化运动；这是创意示意，不作经过验证的空气动力学性能声明。

实际提交的英文Prompt

Create a 10-second product film for an original matte-white cycling helmet with six visible top ventilation slots and a black retention strap. The helmet sits on a discreet dark support inside a minimal studio. Seconds 0–4: a slow front-to-side camera move reveals shell thickness and realistic surface texture. Seconds 4–7: a few restrained translucent airflow ribbons enter the front slots and emerge from the rear, following plausible continuous paths without passing through solid shell sections. Seconds 7–10: the ribbons fade and the camera holds a clean side profile with space on the left. No cyclist, certification badges, safety promises, numerical performance claims, text or changing slot count. Deliver one coherent ten-second clip. Avoid speed ramps, unrelated cutaways and abrupt changes in camera direction; preserve the specified subject throughout.

雨中露营灯产品演示

应用行业：户外产品/电商视频。

保留参考露营灯的橄榄色外壳、圆柱灯罩、折叠提手和调光旋钮，展示雨中操作与光线变化；具体动作顺序及产品约束以真实Prompt为准。

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

Use the supplied original camping lantern as the exact product reference. Preserve its olive metal housing, clear cylindrical diffuser, warm internal light and folding top handle. Create a 10-second scene on a sheltered wooden campsite table at dusk. Seconds 0–4: gentle rain falls beyond the table edge while a slow camera push reveals droplets on the lantern housing. Seconds 4–7: a natural adult hand rotates the existing dimmer once, and the warm light increases smoothly without changing color. Seconds 7–10: the hand leaves and the lantern illuminates nearby folded canvas and a metal cup. Keep the enclosure and handle rigid. No new buttons, logos, IP ratings, safety claims or dramatic storm effects. Deliver one coherent ten-second clip. Avoid speed ramps, unrelated cutaways and abrupt changes in camera direction; preserve the specified subject throughout.

博物馆动态装置短片

应用行业：文化/展览推广。

以七个铝制圆盘的原创装置为参考，制作受控运动的展览推广短片；检查圆盘数量、悬挂关系和镜头过程中的结构连续性。

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 original suspended kinetic sculpture for a 10-second square exhibition film. Preserve all seven brushed-aluminum discs, their relative sizes, thin suspension wires and the circular arrangement. In a quiet white gallery, rotate the discs very slowly at slightly different angles while one broad soft light creates moving elliptical shadows on the rear wall. The camera should make a subtle three-percent push-in and remain level. During the final two seconds, ease the sculpture toward its opening arrangement so an editor can make a near-seamless loop. Keep wires attached, disc count constant and reflections physically coherent. No visitors, text, added discs, impossible intersections or claim that the output is already a mathematically seamless loop. 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。本文不根据缺失或规格不一致的输出推算节省金额。

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 luxury fashion detail film with an adult model wearing a charcoal tailored coat. Begin close on the shoulder seam and lapel with soft window light, shallow depth of field and visible wool texture. Seconds 0–4: the camera tracks slowly along the lapel as the model turns only slightly. Seconds 4–7: one natural hand fastens a single large dark button without obscuring the coat construction. Seconds 7–10: pull back to a waist-up three-quarter portrait against a warm-gray studio wall. Keep the same face, coat geometry, button count and fabric texture throughout. No text, brand marks, extra fingers, instant outfit changes or exaggerated wind. If sound is generated, use only subtle cloth movement and quiet room ambience. Deliver one coherent ten-second clip. Avoid speed ramps, unrelated cutaways and abrupt changes in camera direction; preserve the specified subject throughout.'
headers = {"Authorization": "Bearer " + os.environ["MODELGO_API_KEY"]}
payload = {'model': 'minimax-h3',
 'prompt': prompt,
 'resolution': '2K',
 '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。

音频请求与实际交付：原始记录中，两个平台均将音频开关设为false，但返回文件仍检测到音频流。“含音轨”仅说明文件中存在音频流，不代表已确认有可听声音或音频开关生效。代码保留真实请求参数；本次测试无法确定返回文件未体现该开关的原因。

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。
