WanVideo 2.1: 14B-parameter open-source video generation competitive with Sora
In one sentence Alibaba releases WanVideo 2.1, a 14B open-source model for T2V and I2V with quality competitive with Sora and drastically lower operating cost, available on HuggingFace.
OpenAI's Sora had impressed everyone for video quality, but remained inaccessible to most users and developers. Alibaba's WanVideo 2.1 changes this situation: an open-source model with similar quality, downloadable and freely usable.
With 14 billion parameters it supports both text-to-video (T2V) and image-to-video (I2V) generation, produces smooth high-resolution videos, and runs on accessible hardware compared to proprietary cloud systems.
Availability on HuggingFace and open licensing made WanVideo 2.1 the most important open-source video model of 2025, integrable into any development pipeline.
