视频大模型

基本介绍

视频大模型包括文生视频和图生视频。文生视频是指通过输入文本描述生成对应的视频内容，而图生视频则是通过输入图片生成相关的视频。视频大模型的应用场景包括影视制作、广告创意、教育培训等领域。

视频模型列表

目前模型广场已上线的的视频生成模型包括：

加载 Serverless API 服务列表...

使用方法

在模型使用界面输入文本描述，模型将生成对应的视频内容。以下是使用 Wan2.1-T2V-14B 模型的示例：

示例代码

模力方舟上所有的视频模型皆使用异步接口方式调用，详情请看模型体验页面的示例代码，或者参考 异步接口使用指南。

python

import requests
import time
import json
import webbrowser

	return {"status": "timeout", "message": "maximum wait time exceeded"}

		# Do something with the task result here
		print("Task completed successfully!")
