Output
Not a MiniMax release. fal post-trained it on the open weights of MiniMax H3, and it runs nowhere else.
MiniMax published H3 as open weights. fal kept training on top of them and never released the result, which is why every other route to this family hands you base H3 and only fal hands you Max. The extra training shows up on the public boards: H3 Max sits first on the Design Arena image to video ranking with 1341 Elo, eight points above the base H3 it was built from, and first on the Artificial Analysis board for image to video with audio, where it is listed under the fal internal name MiniMax H3 Turbo (768p).
Speed is the part you feel. A five second 768P clip comes back in 2.87 seconds of inference for text to video and 1.87 seconds for image to video, with the full round trip including queue and download landing near nine seconds. What pays for that is resolution. H3 Max stops at 768P while base MiniMax H3 keeps a 2K tier, so this is the model you explore on, and base H3 is where a 2K deliverable finishes.

fal says the post-training run brought in a large amount of new data pointed at two targets: doing what the prompt says, and looking good doing it. A large share of that compute went to reinforcement learning on tasks with a checkable answer, so the model is scored against something verifiable rather than a mood.
The architecture was designed against the stack it runs on, an engine fal has been tuning for diffusion models for four years. Weights and runtime were shaped together rather than one being ported onto the other.
fal states the order of work plainly: settle the quality, then compress the time. The speed here is the second pass of that process, not a lower quality preset you opted into.
768P is the ceiling and there is no tier above it. Anything that has to finish above 768P belongs to base MiniMax H3, which keeps its 2K option. What is left is where the speed pays for itself: shot exploration, short social cuts, bookended product moves.
Compare with base MiniMax H3A five second clip comes back in about three seconds, faster than it plays. You stop batching jobs and start iterating, because the answer arrives before you look away.
A lone ferry cuts across a harbour at dawn, mist lifting off the water, gulls crossing the frame, the city skyline resolving out of the haze behind it, slow forward drift, cold blue light warming as the sun clears the buildings
Name the sequence and it arrives as a sequence. Prompt adherence is the trait it leads on, so a shot with three stated actions plays all three instead of averaging them into one mood.
A woman in a workshop picks up a chisel, blows dust off a half-carved bowl, turns it once in the light, then sets it down and reaches for sandpaper, warm afternoon light through a dusty window, unhurried handheld framing
Room tone, foley and ambience are generated with the picture, cut to what is on screen. There is no mute switch: steer the mix by naming what should be heard in the prompt.
Stop-motion felt puppets: a small bear in a striped scarf pushes open a tiny cabin door, steps into falling paper snow, looks up, and catches a flake on its nose, visible stitching and fibres, warm practical lamp light on a miniature set
Image to video takes a first frame and an optional final keyframe, so you can fix where the shot starts and where it lands and let the model fill the motion between them.
Macro shot of honey drawn slowly off a wooden dipper into a glass jar, the ribbon folding on itself and settling, morning window light raking across the surface, shallow focus, tiny bubbles rising through the amber
Try eight framings of the same scene in the time one render used to take. Iterate on video the way you iterate on stills, then take the keeper to a higher resolution model to finish.
Vertical or square clips that arrive already carrying ambience and foley, so a post is ready without a separate audio pass.
Write the beats in order and they play in order: a hand reaches, lifts, turns, sets down. Multi-step motion holds together instead of collapsing into a single gesture.
Give it the opening frame and the closing frame of a product shot and let it fill the move between them, so the start and end stay exactly on brand.
How the model works, based on public documentation and sourced evidence.
MiniMax H3 Max is fal's post-trained variant of MiniMax H3, co-optimized with fal's own inference stack and served only through fal. It generates video from a text prompt or animates a still image, and it produces a synchronized audio track in the same pass: room tone, foley and ambience arrive cut to what is on screen. Output runs 5 to 15 seconds at 480P or 768P, and 768P resolves to 1344x768 at 24 fps.
The headline is speed. A 5 second 768P clip comes back in 2.87 seconds of inference for text-to-video and 1.87 seconds for image-to-video, with the full round trip including queue and download landing near 9 seconds. That is faster than the clip itself plays back, and it is the reason to reach for this model over the base H3 that also sits on Vidney.
The trade is resolution. Base MiniMax H3 offers a 2K tier; H3 Max stops at 768P. Everything above 768P still belongs to the base model. In exchange H3 Max leads the public quality boards on overall quality, prompt understanding and aesthetics, and it holds art direction across shots rather than drifting.
The audio track is not optional and there is no mute switch, because sound is generated inside the same pass as the picture. Steer it from the prompt instead by naming what should be heard. Image-to-video also accepts a final keyframe, so you can pin both ends of the shot and let the model fill the motion between them.
H3 Max is the model you open when you want to iterate on a shot instead of waiting for one. It is fal's post-trained build of MiniMax H3, tuned together with the inference stack it runs on, and a five second clip comes back with under three seconds of generation time. That turns video into something you revise the way you revise an image: change a clause, run it again, compare. Sound arrives with the picture in the same pass, so a clip has room tone and foley before you open an editor. The fair comparison is the base MiniMax H3 that also sits on Vidney: pick base H3 when the deliverable has to finish at 2K, because H3 Max stops at 768p. Pick H3 Max when you are still finding the shot, when the beat order matters, or when the job is short social video where speed and prompt adherence beat raw resolution.

Recurring themes from public reviews, comparisons and creator write-ups. Both the good and the bad.
The speed changes how the model is used. Reviewers describe iterating on a shot the way you would iterate on an image: change one clause, regenerate, compare, rather than queueing a render and walking away. Prompt adherence is the second most cited strength, with beats arriving in the order they were written instead of being averaged into a single mood.
The 768P ceiling is the recurring complaint from anyone who needs a finishing resolution rather than a draft. The other is the audio track: it is generated whether or not the project wants it, so a silent deliverable means stripping the track after the fact. Prompt expansion also rewrites the prompt before generation, which helps thin prompts and can soften very deliberate ones.
