SDMLX Acceleration Patches

Pre-mapped SDXL and FLUX.1 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

SDXL

FLUX.1

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

Source Licenses

These packages are transformed LoRA factors. They are provided with source attribution and remain subject to their upstream licenses:

• dmd2_*: source tianweiy/DMD2, Hugging Face metadata lists cc-by-nc-4.0; the model card text names Creative Commons Attribution-NonCommercial-ShareAlike 4.0.
• sdxl_lightning_*: source ByteDance/SDXL-Lightning, license openrail++.
• lcm-lora-sdxl: source latent-consistency/lcm-lora-sdxl, license openrail++.
• Hyper-SDXL-*: source ByteDance/Hyper-SD; SD-related Hyper-SD models are covered by the CreativeML Open RAIL++-M license in the upstream LICENSE.md.
• Hyper-Flux.1-Dev-4-step-Lora: source Lingyuzhou/Hyper_Flux.1_Dev_4_step_Lora. No substantive upstream license grant is documented: Hugging Face metadata says license: 123 and the included LICENSE file is empty (checked 2026-08-04). Do not assume redistribution or commercial-use rights; verify the upstream terms or obtain permission. Use is also subject to applicable FLUX.1 Dev terms.

Do not publish or redistribute packages whose upstream license does not fit your use case. In particular, DMD2 is non-commercial/share-alike. OpenRAIL++ and OpenRAIL++-M packages include use-based restrictions that downstream users must follow.

The SDMLX code license does not relicense these packages. For the repository-level notice, see THIRD_PARTY_NOTICES.md in the SDMLX code repository.
