minimax/hailuo-02-fl2v: [Core Function] Hailuo 02 FL2V is a First-Last frame transition video model. [Strengths] It excels at generating a logical, physically accurate video transition that bridges a provided starting frame and an ending frame. [Best For] Highly recommended for: visual morphing, before-and-after transitions, and precise narrative storyboard completion. [Limitations] Do NOT use this model if you only have one image (use standard I2V instead). Note that Hailuo 2.3 does not support FL2V, so this is the primary transition model. [Routing] Use this model exclusively when the user provides BOTH a first frame and a last frame for a transition.
minimax/hailuo-02-i2v: [Core Function] Hailuo 02 I2V is an image-to-video model optimized for physical realism and sustained high resolution. [Strengths] It excels at animating broad scenes, maintaining complex physics, and supporting native 1080p generation for up to 10 seconds. [Best For] Highly recommended for: animating product photography, bringing landscape/nature photos to life, and generating physically accurate motion. [Limitations] Do NOT use this model for animating complex human facial micro-expressions or highly stylized anime art, where Hailuo 2.3 is superior. [Routing] Use this model when the user needs to animate a landscape/product, or explicitly requires 10 seconds of 1080p video. Otherwise, default to Hailuo 2.3 I2V.
