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-t2v: [Core Function] Hailuo 02 T2V is a text-to-video generation model optimized for physical realism. [Strengths] It excels at complex physics simulation, fluid dynamics, broad cinematic scenes, and natively rendering 1080p video up to 10 seconds without downscaling. [Best For] Highly recommended for: product commercials, high-speed sports action, nature documentaries, and sweeping landscapes. [Limitations] Do NOT use this model for highly stylized anime/art or nuanced human micro-expressions, where Hailuo 2.3 performs better. [Routing] Route to this model when the user requests ‘1080p for 10 seconds’, complex physical action (like splashing water or crashes), or broad landscapes. For human characters and stylization, use Hailuo 2.3 T2V.
