About FLUX 3 Max

FLUX 3 Max is a fast video generation model in Black Forest Labs' FLUX 3 family, created by fal Research by post-training and inference-optimizing FLUX 3 Video in partnership with BFL. It generates video with native audio from a text prompt, from a first (and optional last) frame, or from a set of keyframes, at 5 to 20 seconds, 720p or 1080p, and seven aspect ratios plus auto, with an optional prompt-reasoning step. fal says it generates a 10-second video in about 12 seconds and improves on FLUX 3 Video's quality while being 11.5x faster.
