Alibaba: wanx2.1-kf2v-plus API

Wanx2.1-kf2v-plus is a professional-grade Key-Frame to Video (KF2V) foundation model under the Tongyi Wanxiang series. Unlike standard I2V models that only take a single starting image, the "plus" version utilizes a 14-billion parameter architecture to process both a starting and an ending frame. This allows the model to interpolate complex, high-fidelity motion between two specific visual states, ensuring that the generated video not only begins with the source image but also accurately concludes with the target frame. It is ideal for professional animators and creators who require precise control over story progression and spatial consistency.
