Benchmark: Minimax H3 runs on 8GB VRAM with optimized attention
Zironic · reddit · 2026-08-27
Benchmark results show Minimax H3 can run at 1376x768 resolution on 8GB VRAM cards. With optimized attention routes, the model adds roughly 5.8–6.3 GiB over idle, peaking at 7.0–7.4 GiB total. The author released the H3 Optimizations node (v0.2.13), which supports FROST BF16, SageAttention, and PlagueKind SLA, making local generation more accessible.
