Alibaba: wan2.5-i2v-preview API

Wan2.5-i2v-preview is a foundational multimodal video generation model from Alibaba's Tongyi Wanxiang series. It serves as a research preview that pioneered native audio-visual synchronization in the Wan series. The model can transform a single static image into a high-definition video (up to 1080p) while simultaneously generating matching sound effects, ambient noise, or speech. It excels in prompt adherence and temporal consistency, making it a powerful tool for cinematic storytelling and digital human animation (lip-sync support).
