MiniMax Launches H3 Max: Real-Time Video Generation Faster Than Playback

The H3 Max, developed jointly by MiniMax and fal, boosts video generation speed to under 3 seconds for a 5-second video, with throughput about 35x that of the original H3. This speed means generation time is shorter than playback time; viewers haven't finished watching the previous segment before the next is ready.

In real-world testing, it took 7 seconds from sending the prompt to receiving the result, but that includes intermediate steps like task submission, queueing, and communication; the actual generation time is almost instantaneous. H3 Max currently supports 768p resolution, lower than the standard H3's 2K, but visual quality is not compromised.

H3 Max's speed has spawned new application scenarios. fal engineer Rehan Sheikh created the 'Cross-Dimensional TV' channel, where all visuals and audio are generated in real time by the model; clips have garnered 5.4 million views on X.

Independent developer Pieter Levels launched an AI live streaming website where viewers request content, and the AI produces it instantly. Another fal engineer, Alex Koumpas, started a continuous story live stream where viewers can change the plot direction via text commands.

Within a week, three people, without prior coordination, independently created three AI live streaming rooms, attributed to H3 Max's speed advantage.

Despite the significant speed increase, H3 Max does not compromise on quality. It ranks first in image-to-video on both Artificial Analysis and Design Arena leaderboards.

In real design tasks, H3 Max delivered five complete ad clips with smooth visuals and plausible physics. It currently supports first and last frame reference but not the standard version's subject reference mode.

The real-time AI live streaming model enabled by H3 Max is seen as a watershed in the video generation field, directly eliminating the waiting process and opening a new commercialization path.

Unlike code generation, video has no single correct answer; aesthetic differences mean competition won't rely solely on price, and user stickiness deepens with usage. When creators use a specific model to form a visual style, switching models means changing visual assets and audience expectations, with migration costs accumulating.

Open source and an open ecosystem constitute additional barriers. H3's open source downloads reached 24 million in three weeks, with over 300 derivative models; community feedback feeds back into model iteration, creating a flywheel effect.

The capital market has recognized MiniMax's commercialization capabilities. Morgan Stanley recently maintained an Overweight rating with a target price of HK$900. That day, MiniMax's Hong Kong-listed shares closed up 16.18%, rising from HK$300.4 to HK$349.
