做短视频的神器 Gaga AI 昨天正式发布了。 一张图，一段戏，动作表情声音全配好，做短视频从未如此简单。 使用方式简单到离谱： 上传一张人物图片 + 输入一段台词 = 直接生成影视级对话视频。 不是分步骤的那种，先 TTS、再口型、再表情。而是声音、口型、表情一次性全出，完美同步。 做历史解说、情感电台、知识科普、段子演绎，统统不用真人出镜了。一张图就能搞定一切。

Gaga AI 是由 Sand.ai 团队于2025年10月推出的一款革命性AI视频生成模型。它被形象地称为“一体化AI演员”，其核心功能在于，能够将一张静态的人物照片与一段文字提示相结合，直接生成一段包含同步音频的、影视级别的角色表演视频。

Gaga AI 的突出特点在于其生成内容的质量与自然度。它不仅仅是为人物配上口型，更能创造出极其细腻的面部表情和微动作。无论是微妙的眼神变化、嘴角的弧度，还是伴随说话节奏的头部自然摆动，都使得生成的视频角色充满生命力，情感表达丰富而逼真，达到了“影帝级”的表演水准。另一个关键技术突破是“音画同出”，模型在处理提示词时，会同步生成与画面完美匹配的音频，确保口型与台词高度一致。它不仅支持中文和英文，还能处理包括唱歌在内的复杂发音，甚至支持生成双人对话场景。

在使用上，Gaga AI 非常便捷，极大地降低了专业视频制作的门槛。用户只需访问其官方网站，上传一张清晰的正面人像照片，然后在提示词框中输入表演要求和台词（需用引号括起），系统通常在几分钟内就能生成一段5到10秒的1080P高清视频。这使得它迅速成为短剧创作者、电商卖家、教育内容制作者和游戏开发者的强大工具，帮助他们以极低的成本快速生产高质量的定制化视频内容。

当然，作为一项前沿技术，Gaga AI 目前也存在一些局限，例如不擅长生成大幅度的全身动作，长中文台词偶尔会出现发音不准的情况，并且在处理超过两人的复杂场景时效果尚不稳定。目前该工具处于推广期，用户可以免费使用。展望未来，团队计划推出自定义上传音频、固定角色音色以及支持更长视频和4K分辨率等功能，其发展潜力令人期待。

Introduction to Gaga AI

Gaga AI is a revolutionary AI video generation model launched by the Sand.ai team in October 2025. It is aptly described as a "holistic AI actor," with its core capability being the generation of cinematic-level character performance videos, complete with synchronized audio, directly from a single static portrait photo and a text prompt.

The standout feature of Gaga AI lies in the quality and naturalness of its output. It goes beyond simply animating lip movements to create highly nuanced facial expressions and micro-gestures. Subtle changes in eye expression, the curve of a smile, and natural head movements that follow speech rhythms all contribute to videos where characters feel alive, demonstrating rich and realistic emotional expression that rivals human acting. Another key technological breakthrough is its "audio-visual simultaneous generation." The model processes the prompt to synchronously produce both the video and perfectly matched audio, ensuring highly accurate lip-syncing to the dialogue. It offers robust support for both Chinese and English, can handle complex vocalizations like singing, and even supports generating dialogue scenes between two characters.

In terms of usability, Gaga AI is remarkably user-friendly, significantly lowering the barrier to professional video production. Users simply visit its official website, upload a clear frontal portrait photo, and input a performance description along with the dialogue (enclosed in quotation marks) into the prompt box. The system typically generates a 5 to 10-second 1080P high-definition video within minutes. This has made it a powerful tool for short drama creators, e-commerce sellers, educational content producers, and game developers, enabling them to rapidly produce high-quality, customized video content at a very low cost.

As a cutting-edge technology, Gaga AI naturally has some current limitations. It struggles with generating large, full-body movements, occasionally mispronounces longer Chinese sentences, and its performance can be unstable when handling complex scenes with more than two characters. Currently, the tool is in its promotional phase and is free to use. Looking ahead, the team plans to introduce features such as custom audio uploads, fixed voice profiles, and support for longer videos and 4K resolution, marking a promising future for this innovative platform.
