H3MD LowVRAM LoRA Loader

Same math and inputs as 'Load LoRA (Bypass, Model Only)', but the LoRA term is computed in token slices and added in place, so no full-size temporaries are allocated.

stack_modeoptCOMBOreplace_like_comfyreplace_like_comfy (default): identical to ComfyUI's bypass loader - every bypass loader REPLACES the previous bypass LoRAs, so in a chain only the LAST bypass LoRA is active (normal/merged LoRAs are unaffected). Swapping nodes keeps your current output. stack: keep all upstream bypass LoRAs active too (also absorbs ones from ComfyUI's own bypass loader). This changes the result if your chain had several bypass loaders.
chunk_tokensoptINT8192256–1048576Tokens per LoRA slice. Peak extra VRAM per layer ~ chunk_tokens x layer width x 2 bytes (8192 x 21504 qkv in bf16 = 0.34 GiB). Lower = less VRAM, slightly slower.
