Running Minimax H3 on DGX Spark: 5-Second Video Costs Only $0.001
GabryIta · reddit · 2026-08-14
The author discussed the economics of running the Minimax H3 video generation model locally on a DGX Spark, arguing for its excellent price-to-performance ratio.
- Performance: Using optimized engines and caching, generating a 5-second video (124 frames, 864x480) takes just 3 minutes and 23 seconds.
- Low Cost: At 120W power draw and $0.20/kWh electricity, a single 5-second clip costs roughly $0.00135. It can produce 425 videos in 24 hours for less than $0.60 in total electricity.
- Discussion: Despite these impressive numbers, community members often advise against the DGX Spark for video generation. The author is seeking comparisons with an RTX 5090 to find the absolute best option.
