Local H3 video gen: 15s clip in ~5 min at zero cost vs ~$0.60 per generation on platforms

AIandDesign · x · 2026-09-22

A post breaks down the economics of running the H3 video model locally: one user generates a 15-second video in about 5 minutes on a 5090 at zero marginal cost, while the same generation on a hosted platform would run roughly $0.60 — enabling endless test-fail-iterate loops without worrying about credits.

AIandDesign jokes that anyone who bought a 5090 before GPU prices exploded will have "earned it back" in just over 3000 such generations, framing a local-vs-cloud iteration cost debate.
