CogVideoX

Đánh giá của chúng tôi — CogVideoX cho phim ngắn

CogVideoX is Zhipu/THUDM's open video line — 2B and 5B models plus the CogVideoX1.5 refresh — and its enduring virtue is the entry price: the README cites diffusers memory floors as low as 4.4GB (2B, INT8) and about 10GB for 1.5-5B. Our read for short drama: a sensible sandbox for prototyping shot generation on modest GPUs before committing to heavier Wan or HunyuanVideo deployments.

Know what you are buying, though. The base 5B outputs 720x480 at 8 fps per the README — well below vertical-drama delivery specs — and prompts are English-only. Licensing splits: 2B is Apache 2.0 while 5B models sit under a custom CogVideoX license. The last major activity we saw dates to March 2025 (the CogKit announcement), so treat it as a stable previous-generation baseline rather than a frontier pick.

• 2B runs from 4.4GB VRAM, per README
• T2V, I2V and video continuation
• Diffusers integration plus ComfyUI wrapper
• CogVideoX1.5-5B outputs 1360x768
