H3 Max Speed Teardown: How Co-Design and Inference Optimization Achieve Faster-Than-Real-Time Video Generation

The article dissects H3 Max's 2.46-second generation of 5-second 768p video, attributing speed to three layers: post-training that reduces sampling steps without quality loss, a co-designed inference stack (Falcon engine) lowering per-step cost, and GB200 hardware; it clarifies inference time vs end-to-end latency, and explains latent refinement versus traditional super-resolution.
