Juggernaut XI Lightning — LocalMuse Core ML

This repository contains the iOS-optimized Core ML conversion used by LocalMuse. It was converted directly from the exact Civitai checkpoint juggernautXL_juggXILightningByRD.safetensors for Juggernaut XL version Jugg_XI_Lightning_by_RD (model version 920957). It is not a merge and does not reuse UNet, text encoder, or VAE weights from another LocalMuse model.

Recommended generation profile

Sampler: DPM++ SDE
Schedule: Karras
Steps: 6 (author range: 5–7)
CFG: 2.0 (author range: 1.5–2.0)
Clip skip: 2 (the SDXL converter exports the penultimate hidden layer)
Native LocalMuse canvas: 1024×1024
Suggested negative prompt: CGI, Unreal, Airbrushed, Digital

Optimization

UNet: 6-bit palettization, split into two Core ML programs
Text encoder 1: FP16
Text encoder 2: 8-bit palettization
VAE encoder and decoder: model-specific FP16 conversion
Attention: SPLIT_EINSUM
Deployment target: iOS 17
Runtime: Neural Engine-preferred UNet and GPU VAE decode in LocalMuse

The compiled payload is fixed at 1024×1024. All large compiled weight files remain below the iOS 1 GiB per-file limit.
