MODEL GUIDE / H3 MAX
H3 Max for live AI video
H3 Max is fal’s post-trained version of MiniMax H3. This guide separates the model’s documented capabilities from the product infrastructure required to turn short generated clips into a continuous broadcast.

What is H3 Max?
H3 Max is a video generation model developed by fal Research through post-training on the open-weight MiniMax H3 base. fal says the additional training focused on prompt adherence and visual quality, while its inference team optimized serving speed. It is offered through fal rather than as a separate live-streaming platform.
The distinction matters. H3 Max produces video clips. Products such as Infinite Slop, fal.live and Renoise Live add the application layer around those clips: viewer input, moderation, queues, world state, playback and any rules that decide what is generated next.
H3 Max output and inputs
fal documents 480p and 768p output with durations from 5 to 15 seconds. Audio is predicted alongside the picture, so dialogue, effects and room tone can arrive synchronized with the generated frames instead of being attached in a separate pass.
The available workflows include text-to-video, image-to-video and reference-to-video. Text-to-video begins with a prompt. Image-to-video uses a still as the opening frame and can optionally use an ending frame. Reference-to-video can condition a generation on supplied images, video or audio, with separate reference-input charges after the included allowance.
Why its speed matters for live video
fal reports that a five-second 768p clip can be generated in under three seconds. That is the threshold that makes faster-than-playback generation possible: an application can begin preparing the next clip while the current five-second segment is still on screen.
The reported number is model inference time, not a promise that every viewer action appears three seconds later. Prompt rewriting, safety checks, traffic, generation queues, storage and delivery can add latency. Watch AI Streams therefore treats the number as a sourced performance claim rather than an independent benchmark or a guarantee of uninterrupted broadcasting.
H3 Max pricing and continuous-stream economics
As verified on September 8, 2026, fal lists standard video output at $0.05 per generated second for 480p and $0.08 per generated second for 768p. That makes one finished 768p minute $4.80 before any additional product costs.
A live channel multiplies that output rate by time. One hour of uninterrupted 768p generation is $288 in raw output. Real operating cost can be higher because reference inputs, failed generations, moderation, storage, bandwidth and application infrastructure are outside that figure. Use the homepage calculator to test hours, resolutions and channel counts without treating its result as a full production budget.
What H3 Max does not solve
Fast clips do not automatically create coherent television. A product still has to decide how prompts enter the queue, how harmful requests are handled, whether characters and locations persist, how a failed generation recovers and what the player shows while the next segment is unavailable.
Those design choices explain why H3 Max streams feel different even when they share a model. Some optimize for public chaos, others for themed worlds or personal characters. The directory compares those viewer-facing systems instead of reducing every project to a model label.
