CogVideo AIで、あなたのアイデアを驚きの動画に。

CogVideo is an AI video generator that turns text, a single image, or an existing clip into a short video, right in your browser. It runs on the open CogVideoX model line, and this site offers that technology as a hosted service so you do not have to install anything. You describe or upload what you want, and it renders the video on our servers.

CogVideoX is the family of open text-to-video and image-to-video models that CogVideo is built on, developed by the THUDM research group. It includes several releases, such as CogVideoX-2B, CogVideoX-5B, the CogVideoX-5B-I2V image-to-video model, and the newer CogVideoX 1.5. On cogvideo.net you use these models hosted, with no setup and no GPU of your own.

CogVideoX-2B is the smaller, lighter model, built to run efficiently on modest hardware and generate faster. CogVideoX-5B is the larger model, tuned for higher detail and more coherent motion when final quality matters most. On our hosted service you can simply pick the output you want without managing either model yourself.

That depends on which model you run and the resolution and length you target, with the lighter CogVideoX-2B needing far less than the larger CogVideoX-5B. We keep a dedicated guide with directional VRAM and GPU figures for each model so you can plan a self-hosted setup. If you would rather skip the hardware question entirely, generation on cogvideo.net runs on our servers. See the system requirements guide for the full breakdown.

CogStudio is a community app for running CogVideoX yourself, often used for CogStudio image to video and other local workflows. It is a way to drive the same open models on your own machine. cogvideo.net gives you that model line fully hosted instead, so there is nothing to install and no local GPU required.

Yes. You can start generating videos for free, no card required, so you can test text to video and image to video before you spend anything. When you need more volume or faster turnaround, you can choose a monthly plan or pay once for a credit pack, and cancel anytime.

No. Generation runs on our servers, so CogVideo works on any laptop, even a Chromebook, and on your phone. You only need a browser and an internet connection. If you would rather run the open model on your own machine, see the system requirements guide for the hardware you would need.

You can make short clips from a written prompt, add motion to a single still image, or restyle footage you already have. That covers social posts, ad and campaign variations, product animations, explainer visuals, and quick concept demos. Each mode uses the same simple flow: describe or upload, generate, then download.

Text to video builds a clip from a written description, so it is best when you have an idea but no footage. Image to video animates a still you already have, keeping your subject, colors, and framing while adding motion. Use text to video to invent a scene from scratch, and image to video to bring one specific picture to life.

CogVideo is built on the open CogVideoX model line, which traces back to the original open research model released by THUDM (also known from its GitHub project). The models themselves are open and inspectable. cogvideo.net is the hosted, no-setup way to use them without wrangling code, weights, or a GPU.

It gives you text to video, image to video, and video to video in one browser tab, with a free tier, no install, and no GPU. Because it is built on the open CogVideoX line, you know exactly which model family is behind your videos. For a full side by side on quality, speed, and price, see the comparison on the blog.
