Wan 2.1 Video Models

Wan 2.1 is Alibaba's landmark open-source video generation model series that set a new standard for accessible, production-ready AI video when it launched. Available in 480p and 720p resolution variants for image-to-video, plus a powerful text-to-video model, Wan 2.1 delivers smooth motion synthesis, accurate subject tracking, and natural scene dynamics across a wide range of content types. The models are built on large-scale training and an open architecture that became the foundation for subsequent Wan releases and community fine-tunes. Wan 2.1 is complemented by Wan Animate for targeted object and scene animation, Wan Scail for video upscaling workflows, and Wan Video Effects for creative visual transformations. The 480p variant is optimized for speed and throughput, while the 720p variant delivers higher visual fidelity for production use. Wan 2.1's open-weight design makes it particularly valuable for developers building custom video generation applications, researchers experimenting with video AI architectures, and production teams who need a reliable, well-tested video generation backbone. On Segmind, all Wan 2.1 models are available as pay-per-use APIs — no GPU management, no infrastructure overhead. Integrate professional video generation into your application with a single API call.
