What you can make with the free Flux video generator
Free AI video generation that arrives with its own sound
FLUX 3 generates the audio in the same pass as the picture, so a free draft is a finished clip rather than a silent one waiting on a sound pass.Ambience, effects, and music land locked to the actionSound is described in the same prompt as the shot, no second toolAudio survives draft enhance, with no separate charge for the sound
Draft mode is built for iterating on AI video generation
Draft is FLUX 3's preview render, made for the stage where you are still shaping a shot: generate it, watch it, adjust the prompt, go again.Direct an idea across several takes instead of betting it on one renderEvery draft returns a reusable draft cache tied to that exact takePromote the take you like to a full-quality 1080p render, audio included
Text-to-video AI generation with no starting image needed
A written prompt is the only required input, so there is nothing to upload or prepare before your first free generation.720p output, 5, 10, or 15 seconds in the sandbox, and any length from 5 to 20 seconds over the APILandscape, square, and vertical framing, so social cuts come out of the same modelPhotoreal, animated, and stop-motion looks from the same model
Every FLUX 3 video generation endpoint on fal
The free allowance covers exactly one of these: FLUX 3 text-to-video draft, five generations a day. Every other endpoint below is pay-per-use with no subscription, whether you are animating a still, working from keyframes, extending a clip, or finishing a draft at full quality.

How to prompt the free Flux video generator
Draft renders are made for iterating, so treat your five a day as five attempts at one idea rather than five separate ones.
1. Describe the shot, not just the subject
2. Write the sound into the prompt
3. Iterate free, then pay only for the keeper
What are some examples of free FLUX 3 video?
Every clip below was generated on FLUX 3 from the prompt shown, with nothing added afterwards. Turn on audio to hear the native sound generation.
A 1987 local news report from the mall
"a 1987 local news report about teenagers hanging out at the mall"
A 1970s film-grain desert drive
"Sun-bleached 1970s film-grain shot from inside a convertible on an empty desert highway, driver's hand riding the wind out the window, heat shimmer over the asphalt, red mesas sliding past. Wind buffeting, tyre hum, a soft rock station drifting in and out of signal."
Stop-motion claymation in a tiny kitchen
"Stop-motion claymation of a round hedgehog baker rolling dough in a tiny wallpapered kitchen, thumbprints visible in the clay, flour puffing up as it presses out cookie shapes and slides the tray into a glowing oven. Wooden rolling pin, dusty flour puffs, a squeaky oven door."
Frankenstein by Mary Shelley, cut as a trailer
"Visualize Frankenstein by Mary Shelley as a movie."
A sea turtle over a sunlit coral garden
"A sea turtle glides over a shallow coral garden, sunlight fracturing into moving lattices across the sand, small fish scattering off its shell as it banks slowly toward open water. Muffled underwater ambience, rising bubbles, faint reef crackle."
How the pyramids were built, visualized
"How pyramids are made? Visualize it."
Common questions about the free Flux video generator
Is the Flux video generator free?
Yes. Signed-in fal.ai accounts get 5 free FLUX 3 text-to-video draft generations every 24 hours in the fal sandbox. Each one is a 720p clip with native sound, generated from a text prompt, and the allowance refills on a rolling 24-hour window rather than a one-time trial.
How many free Flux videos do I get?
Five every 24 hours, on a rolling window. Each generation is a FLUX 3 draft render at 720p with audio, and you can pick 5, 10, or 15 seconds in the sandbox. Unused generations do not stack up: the allowance refills rather than accumulates.
How do I use the Flux video generator for free?
Type a prompt in the box at the top of this page and press Generate free, which opens FLUX 3 text-to-video draft in the sandbox with the model selected and your prompt already filled in. Sign in, then generate. Your first five videos each day are free.
Do I need an account or a credit card?
You need a signed-in fal.ai account, and activating an account does require a card on file. The five daily generations themselves are free and are not charged against the card; it only comes into play if you generate beyond the free allowance. Signing in is also what keeps the free tier protected from abuse, which is what lets us offer it every day.
Is the free Flux video generator unlimited?
No. It is five FLUX 3 draft videos a day, which resets daily rather than expiring, so it is an ongoing allowance instead of a trial. If you need to generate without a daily cap, the same model is available pay-per-use at $0.06/s of draft video, with no subscription and no minimums.
What is FLUX 3?
FLUX 3 is Black Forest Labs' AI video generation model, and their first video model after the FLUX image family. It generates up to 20 seconds of video with native synchronized audio from a text prompt, a still image, first and last frames, keyframes, or an existing clip. The free tier on this page runs its text-to-video draft render; the full model and every mode are on the FLUX 3 page, and the wider family is on the FLUX page.
What is draft mode in FLUX 3?
Draft is FLUX 3's preview render, for the stage where you are still shaping a shot. It returns a draft cache alongside the video, and runs at $0.06 per second rather than $0.17. Pass that cache to draft enhance and FLUX 3 re-renders the same take at full-quality 1080p, audio included at no extra cost, so you only pay full price for the takes you actually want.
Do the free Flux videos have sound?
Yes. Native audio generation is on by default on FLUX 3 draft renders, so ambience, effects, dialogue, and music are generated in the same pass as the picture and arrive synchronized to the action. Describe the sound you want in the same prompt as the shot.
What are the limitations of the free Flux video generator?
Five generations per 24 hours, text-to-video only, and draft-quality 720p renders rather than the full-quality 1080p output. Draft is a preview render, so fine detail and motion are looser than a finished FLUX 3 clip. Free generation also needs a signed-in account, since the sandbox's signed-out allowance covers image models only. Everything beyond that is pay-per-use on the FLUX 3 endpoints, with no subscription.
Can I generate Flux images for free too?
Yes, and that one does not even need an account: fal's sandbox lets signed-out visitors run FLUX.2 Klein 9B, Black Forest Labs' open-weight image model, as free text-to-image. This page's free tier is the video side. The full image family is on the FLUX page.
What if I need more than five videos a day?
The same endpoints are pay-per-use with no subscription and no minimums. Draft renders are $0.06 per second, so a 5-second draft is about $0.30. Full-quality text-to-video is $0.17 per second at 720p and $0.29 per second at 1080p, and enhancing a draft you already like is $0.29 per second at full-quality 1080p with audio included. Start from the draft endpoint or the FLUX 3 page.
Can I use the free videos for commercial projects?
Yes. Content generated through fal.ai can be used in commercial projects. Check fal.ai's terms of service for full details on usage rights and licensing.
Scale beyond the free tier with the FLUX 3 API
The client API handles the request submit protocol. It will handle the request status updates and return the result when the request is completed.
import { fal } from "@fal-ai/client";
const result = await fal.subscribe("blackforestlabs/flux-3/text-to-video/draft", {
input: {
prompt:
"A cellist plays in a tiled subway station, bow biting into the strings, a train rumbling through the far platform. Warm resonant cello, coins, distant train roar.",
duration: 5,
aspect_ratio: "16:9",
generate_audio: true,
},
logs: true,
onQueueUpdate: (update) => {
if (update.status === "IN_PROGRESS") {
update.logs.map((log) => log.message).forEach(console.log);
}
},
});
// Keep draft_cache.url to enhance this exact take later.
console.log(result.data.video.url, result.data.draft_cache.url);
