MiniMax H3 Max

MiniMax H3 Max is a speed-optimized video generation model built by fal on top of the open-weight MiniMax H3 base model. Designed specifically for high-throughput and low-latency workflows, H3 Max is post-trained for stronger prompt adherence and improved visual aesthetics, capable of rendering a 5-second, 768p clip with natively synchronized stereo audio in under three seconds.

Capabilities and Architecture

The model supports multiple generation modes, including text-to-video, image-to-video with optional start and end frames, and reference-to-video conditioning using up to twelve multi-modal inputs. By focusing optimization directly on the inference stack alongside model post-training, H3 Max trades the high-resolution 2K upscale phase of the original base model for rapid, real-time generation speeds at a native resolution ceiling of 768p.

Prompting Tips

For optimal results with MiniMax H3 Max, timestamped text prompts detailing second-by-second changes perform effectively. Because the model generates native audio alongside the video frames, explicitly describing the desired soundscape improves overall output quality. When aiming for character or style continuity across multiple generations, supplying the previous clip or its final frame as a reference helps anchor the visual narrative.
