Can MiniMax H3 run on a 4090? Users weigh RAM spillover needs

1thatonedude1 · reddit · 2026-09-30

A Reddit user asks whether MiniMax H3—the open-weight video model everyone's talking about—can run on a newly acquired RTX 4090, noting it reportedly can't fit on the card unlike LTX 2.5.

He has only 32GB of system RAM and wants to know how much extra memory is needed for spillover, willing to order more if required. No definitive answer yet; useful for anyone planning local video-generation setups.
