Stable Diffusion users struggle with H3 model VRAM limits on 12GB cards

Users on Reddit are reporting significant VRAM limitations when attempting to run the H3 Healthcare Three Hop Index model with NVIDIA's 4070 graphics card, which has 12GB of VRAM. Despite workflows for other models like Wan performing well, H3 consistently causes Out Of Memory (OOM) errors, even with reduced settings. One user attempted a suggested fix involving clearing models between stages, but this did not resolve the issue, leaving them seeking alternative workflows or solutions for 12GB cards. AI
