FLUX 3 Max
Overview
FLUX 3 Max: The Fast, Post-Trained FLUX 3 Video Model
FLUX 3 Max is a video model released on October 19, 2026 by fal Research in partnership with Black Forest Labs. It starts from Black Forest Labs' FLUX 3 and is post-trained for stronger prompt adherence, better image-to-video quality and much lower latency.
This FLUX 3 Max video generator runs both of its launch modes, text to video and image to video, with native audio, 720p or 1080p output and any length from 5 to 20 seconds. You don't need a fal account or API key: write a prompt, pay per second with credits and download the MP4.

FLUX 3 Max Examples with Full Prompts
Real outputs published by fal, one prompt each with no editing. Copy a prompt into the generator above to run it yourself.
A driverless car at the saloon
Prompt
One continuous ten-second Western shot set in the 1880s American frontier, with one piece of startling modern technology that feels out of place. A white driverless electric car with a roof-mounted spinning sensor pulls up silently in front of a frontier saloon with nobody at the wheel; a cowboy cautiously opens the rear door, peers in, and climbs in as the car glides away down the dusty street. Medium shot. Sunbaked western palette, hard sun, warm golden-sepia tones, soft dusty haze, rich 35mm film look with grain and halation, like a 1960s Western. Every person is an original fictional adult. No captions, logos or watermarks.
Sample video by fal
A robot dog working the herd
Prompt
One continuous ten-second Western shot set in the 1880s American frontier, with one piece of startling modern technology that feels out of place. On a frontier cattle ranch, a four-legged robot dog trots alongside a mounted cowboy, nimbly herding a few stray longhorn cattle back toward the corral through the sagebrush; the cowboy tips his hat to it. Wide tracking shot. Sunbaked western palette, hard sun, warm golden-sepia tones, soft dusty haze, rich 35mm film look with grain and halation, like a 1960s Western. Every person is an original fictional adult. No captions, logos or watermarks.

A call from the future
Prompt
One continuous ten-second Western shot set in the 1880s American frontier, with one piece of startling modern technology that feels out of place. Inside a frontier telegraph office, an old telegrapher taps his brass key and a glowing life-size hologram of a woman in a modern suit appears in the air in front of him, speaking; he slowly takes off his spectacles in amazement. Medium shot, warm light, the hologram glowing pale blue. Sunbaked western palette, hard sun, warm golden-sepia tones, soft dusty haze, rich 35mm film look with grain and halation, like a 1960s Western. Every person is an original fictional adult. No captions, logos or watermarks.
Sample video by fal
The mail at full gallop
Prompt
One continuous ten-second Western shot. A pony-express rider at full gallop across open sagebrush country reaches a relay post; a waiting rider on a fresh horse rides alongside at speed and the leather mail pouch is passed from hand to hand without either horse slowing, then the second rider surges ahead. Side-on tracking shot at speed. Sunbaked western palette, hard sun, warm golden-sepia tones, soft dusty haze, rich 35mm film look with grain and halation, like a 1960s Western. Every person is an original fictional adult. No captions, logos or watermarks.

Benchmarks
FLUX 3 Max Speed and Quality Benchmarks
Image-to-video quality from Artificial Analysis's preliminary video arena, and the time each model took to generate a 10-second clip in fal's own test.
| Model | Image-to-video Elo | Time for a 10 s clip | On this site |
|---|---|---|---|
| FLUX 3 Max | 1,139 | 12.45 s | Yes |
| Seedance 2.5 | 1,139 | 277.80 s | No |
| Gemini Omni Flash 1.1 | 1,134 | 47.37 s | No |
| Wan 3.0 | 1,127 | 180.16 s | No |
| FLUX 3 | 1,089 | 126.44 s | No |
Preliminary figures published by fal on October 19, 2026; the arena's confidence intervals overlap between the top models. fal's launch page times a 10-second clip at 12.45 s and its press release at 10.95 s; real waits depend on settings and load.

Features
Key Features of the FLUX 3 Max Video Generator
Fast enough to iterate
fal measured a 10-second clip at about 12 seconds, roughly ten times faster than FLUX 3. Short waits make it practical to test several prompts in one sitting.
Video and sound in one pass
Every clip comes with matching audio, from hooves and engines to rain and music. Describe the sound in your prompt to steer it.
Any length from 5 to 20 seconds
Pick the exact clip length you need in 1-second steps instead of fixed 5 or 10 second presets, and only pay for the seconds you generate.
First and last frame control
In image to video, upload the frame the shot starts from and, if you like, the frame it should end on. The model fills in the motion between them.
Faces and motion that hold up
Post-training targeted visual fidelity and motion coherence, so close-ups keep their detail and fast action stays physically believable.
720p or 1080p in six ratios
Render widescreen, vertical, square or 21:9 cinematic clips at 720p for drafts or 1080p for delivery.
Pricing
FLUX 3 Max Price Per Video
Every clip is billed per second of output, with audio included. The exact cost is shown on the generate button before you start.
| Length | 720p | 1080p |
|---|---|---|
| 5 seconds | 105 credits | 175 credits |
| 10 seconds | 210 credits | 350 credits |
| 15 seconds | 315 credits | 525 credits |
| 20 seconds | 420 credits | 700 credits |
Credits are returned automatically if a generation fails. Credits come with a subscription, from $9.90 per month billed annually, or a one-time pack on the pricing page.
Prompt guide
How to Write FLUX 3 Max Prompts
fal's own sample prompts follow the same structure. Build your prompt in this order and keep it to one continuous shot.
1. Shot and length
One continuous ten-second shot.
2. Scene and subject
A street musician in a rainy neon alley…
3. Action in order
…lifts her trumpet, plays a short phrase, then lowers it.
4. Camera
Slow push-in, 50mm lens look, shallow depth of field.
5. Look
Pink and blue neon, rich 35mm film grain.
6. Sound and limits
Sound of the trumpet and soft rain. No captions, logos or watermarks.
Tips for better FLUX 3 Max results
- Give the shot one main action. Packing several unrelated events into one clip makes the result harder to control.
- For longer clips, add timing beats such as "seconds zero to two… seconds two to four…" so the action fills the whole length.
- Name the sounds you want to hear. The model generates the audio from the same prompt as the picture.
- In image to video, describe what changes from the first frame instead of describing the frame again.
- Test an idea at 720p and a short length, then render the version you like at 1080p.
