MiniMax Hailuo 2.3 Fast
What is MiniMax Hailuo 2.3 Fast?
MiniMax Hailuo 2.3 Fast is the image-led speed model in the Hailuo family. A start image is required, the prompt is optional, and turnaround is shorter than Hailuo 2.3. Output is 768p (default) or 1080p in 6 or 10 second videos; 1080p locks to 6 seconds. When you do pass a prompt, it runs up to 2000 characters, with an optional prompt_optimization rewriting pass.
Best for
Fast teasers from key art
Send the image, skip the prompt, get motion back quickly.
High-volume image-to-video pipelines
Shorter turnaround per video keeps batch queues moving.
Thumbnail-to-video social posts
Animate existing thumbnails without writing prompts.
When to use Hailuo 2.3 Fast
Pick 2.3 Fast when every job starts from an image and the latency budget is tight. When users may send text alone, route through Hailuo 2.3 instead. For 2K output with native audio and reference control, step up to Hailuo 3.0.
