CogVideo AI wraps the open CogVideo and CogVideoX research models in a hosted web app so you don't have to install anything or rent a GPU. The site offers three core workflows: text to video, image to video, and video to video. You type a prompt or drop in an image, hit generate, and the model renders a short clip on the vendor's servers in a few minutes. A built-in prompt helper suggests wording that tends to produce cleaner results, which lowers the learning curve for people who have never written a diffusion prompt before.
The service is explicit that it is a third-party hosting layer, not the upstream project. It documents the model line it runs on — CogVideoX-5B for higher quality, CogVideoX-2B for lighter and faster output, CogVideoX-5B-I2V for image-to-video, the newer CogVideoX 1.5 for higher resolution and longer clips, plus the original CogVideo research model — and links out to the open-source GitHub repository for people who would rather self-host with CogStudio or ComfyUI.
Pricing follows a credit model. There is a free entry point, then monthly tiers such as Starter at about $9.90 per month when billed yearly, and Pro at roughly $24.90 per month, alongside one-time credit packs. Paid plans unlock standard or higher video quality, all models, private generation, prompt optimization, unlimited downloads, and a commercial license. Generation happens server-side, so any modern laptop works as long as you have a browser.
