WAN 2.1 I2V
WAN 2.1 I2V costs $0.360/clip on FairStack — a image to video model for Image animation, Product animations, Social media video from stills. No subscription required. Pay per generation with full REST API access. FairStack applies a transparent 20% margin on infrastructure cost so you always see the real price.
What is WAN 2.1 I2V?
WAN 2.1 I2V is Alibaba's foundational image-to-video model, animating still images into video using the WAN architecture at $0.30 per generation. It preserves visual fidelity from source images while adding natural motion, serving as the entry-point I2V model in the WAN ecosystem. The model maintains the color palette, style, and visual characteristics of the input image while adding coherent motion. WAN's motion understanding produces natural-looking animation for standard subjects including people, objects, and scenes. The model handles common animation tasks reliably. Compared to WAN 2.2 I2V and WAN 2.6 I2V which offer improved detail preservation and motion quality at similar or slightly higher prices, WAN 2.1 I2V is the oldest option in the family. Against Kling v2.1 Pro I2V which provides 1080p output with more sophisticated motion, WAN 2.1 offers a simpler, more affordable alternative. Newer WAN versions are recommended for new projects. Best suited for basic image animation, product and scene animation from stills, social media video from existing photography, and WAN ecosystem workflows where the 2.1 version's behavior is preferred. Available on FairStack at infrastructure cost plus a 20% platform fee.
