What is FLUX 3 Max?

Black Forest Labs’ video model, tuned for quality.

FLUX 3 Max comes from Black Forest Labs, the team behind the FLUX image models. It is a post-trained version of FLUX 3 Video, tuned for stronger prompt adherence and better visual quality while staying fast.

It writes the picture and the sound together, holds a shot for up to 20 seconds, and can animate from a start frame to an end frame you choose. That makes it a good fit for longer single takes, product reveals and scenes where the atmosphere matters.

On Nano Banana you run FLUX 3 Max in the browser: in the Video Studio, in Banana Computer, or through the API. No separate account, no per-model bill.

The longest take

From 5 to 20 seconds in a single generation: the longest clip of the video models on Nano Banana. Fewer cuts to stitch, more room for a scene to breathe.

Sound in the same pass

Describe the rain, the crowd or the engine in your prompt: the audio is generated with the picture and comes out in the same MP4.

Start and end frame

Give the first image, and optionally the last one: FLUX 3 Max animates between them. Ideal for before-and-after, transformations and product reveals.

Every format you post

Seven aspect ratios, from 21:9 cinema to 9:16 for Reels, TikTok and Shorts, in 720p or 1080p.

Built to follow the brief

Black Forest Labs post-trained FLUX 3 Max on top of FLUX 3 Video for prompt adherence and image quality. Camera moves, lighting and style notes in your prompt are kept, not averaged away.

“Rainy neon-lit Tokyo alley at night, a courier on a bicycle splashes through puddles toward the camera, steam rising from street food stalls, reflections on wet asphalt, slow tracking shot, cinematic. Sound of rain, bicycle tyres on water and distant city ambience.”

“Close-up of a glass perfume bottle on wet black stone, a single drop of water slides down the glass, soft golden rim light, slow orbiting camera, luxury product commercial. Gentle water droplet sounds.”
