fal rebuilt MiniMax's open-source H3 video model to run 35x faster, pushing GPUs to 70-80% of ceiling

In an a16z interview, fal's Gorkem Yurtseven and Batuhan Taskaya explain how they rebuilt inference for MiniMax's open-source H3 video model: fewer generation steps and rewritten stage code pushed GPU utilization from the typical 30-40% to 70-80% of theoretical ceiling — a 35x speedup with no quality loss. Generation is now faster than filming, and user demand has shifted from speed/cost to quality and prompt adherence.
Pro workflow: VFX artists render a low-res scene in Blender and feed it to the AI model for near-100% controllability; a week after H3 Max launched, an entirely new pipeline emerged — using an LLM (Astra) to build the Blender scene, then passing it to H3 Max.
