 "title": "Fix for MiniMax-H3 not fitting on a single RTX PRO 5000 48GB when running local video+audio generation",
 "symptom": "MiniMax-H3 ships as ~135 GiB of BF16 weights per task partition (2x66GB DiT + 51.5GB Qwen3-VL-32B text encoder + VAEs). Official recipes call for 4x H200. vLLM-omni's single-GPU --enable-cpu-offload path documents a 200+ GiB system RAM minimum (384 recommended), so it cannot start on a 123 GB box.",
