SDMLX Acceleration Patches

Pre-mapped SDXL acceleration patches for SDMLX / ComfyUI on Apple Silicon.

These packages are not fully expanded UNet deltas. They contain SDMLX-mapped low-rank LoRA factors:

• target keys already match the SDMLX MLX UNet
• linear factors use [out, rank] and [rank, in]
• Conv2D down factors use MLX layout [rank, kernel_h, kernel_w, in]
• runtime scale is strength * alpha / rank

Each .sdmlxpatch package contains:

• patch.safetensors
• manifest.json
• optional source_metadata.json

Packages

Package	Recommended Steps	CFG	Sampler	Scheduler	Force No CFG
dmd2_sdxl_4step_lora_fp16.sdmlxpatch	4	1.0	lcm	normal	true

sdxl_lightning_8step_lora.sdmlxpatch	8	1.0	lcm	normal	true
lcm-lora-sdxl.sdmlxpatch	8	1.0	lcm	normal	true
Hyper-SDXL-8steps-CFG-lora.sdmlxpatch	8	5.0	lcm	normal	false
Hyper-SDXL-12steps-CFG-lora.sdmlxpatch	12	7.5	lcm	normal	false

The recommendations are metadata only. SDMLX should keep sampler settings explicit in the UI.
