| # 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. |
