# 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.
