Wan 2.1 (1.3B) is a lightweight, open-source text-to-video model from Alibaba, released in 2024 as part of the Wan 2.1 series. With a 1.3-billion-parameter architecture, it is optimized for speed and accessibility, running on consumer-grade GPUs with modest VRAM requirements. The model focuses on fast, low-resource 480p video generation rather than high resolution or advanced controls. While newer models now offer greater fidelity and flexibility, Wan 2.1 (1.3B) remains useful for quick experimentation, lightweight workflows, and environments with limited hardware resources.
