Inputs (15)
| Name | Type | Default | Description |
|---|---|---|---|
| model | MODEL | — | |
| profile | COMBO | auto | 5 options: auto, 12GB_VRAM_32GB_RAM, low_vram, balanced, max_speed |
| apply_reserved_vram | BOOLEAN | true | — |
| reserved_vram_mode | COMBO | manual | manual: uses reserved_vram_gb | auto_used_plus: sets EXTRA_RESERVED_VRAM = (used_vram + auto_headroom_gb), like ReservedVRAMSetter |
| reserved_vram_gb | FLOAT | 1.250–24 | Reserved VRAM in GB (manual mode). If profile=auto and this is 0, the node chooses a conservative value. |
| sage_attention | COMBO | auto | 8 options: disabled, auto, sageattn_qk_int8_pv_fp16_cuda, sageattn_qk_int8_pv_fp16_triton, sageattn_qk_int8_pv_fp8_cuda, sageattn_qk_int8_pv_fp8_cuda++, +2 |
| allow_sageattention_torch_compile | BOOLEAN | false | — |
| torch_compile_mode | COMBO | off | auto = try torch.compile with a safe mode (reduce-overhead). On Windows this may still be unstable depending on Torch/driver; if you see crashes, set off. |
| fp16_accumulation | COMBO | auto | 3 options: auto, on, off |
| tf32 | COMBO | auto | 3 options: auto, on, off |
| clean_gpu_before | BOOLEAN | false | — |
| console_log | BOOLEAN | true | Print a short summary (applied + warnings) in the server console. |
| include_hardware_report | BOOLEAN | false | If enabled, probes current hardware and embeds an additional recommendations report into report_json (useful for printing/debug). |
