This repository is an unmodified distribution mirror of darkmaniac7/TokForge-CyberRealistic-V9-CoreML-6bit for the LocalMuse iOS app. The compiled Core ML binary artifacts are preserved unchanged. Model authorship, conversion credit, license terms, and the original model card are retained below.

TokForge — CyberRealistic V9 · CoreML 6-bit (Apple Neural Engine)

A 6-bit palettized Apple CoreML conversion of CyberRealistic V9 (cyberdelia/CyberRealistic, the CyberRealistic_V9_FP16 checkpoint by cyberdelia — an SD-1.5 photorealistic finetune with best-in-class faces and an integrated VAE), built for on-device image generation in the TokForge iOS app. Converted with Apple ml-stable-diffusion (torch2coreml) using SPLIT_EINSUM_V2 attention and --quantize-nbits 6 (6-bit palettized weights), so it compiles fast on the Apple Neural Engine.

Part of the TokForge iOS · CoreML Image Models collection.

Files

File	Size	Contents
Resources/	~913 MB	TextEncoder.mlmodelc / Unet.mlmodelc / VAEDecoder.mlmodelc / VAEEncoder.mlmodelc + vocab.json + merges.txt

The Resources/ tree holds the compiled .mlmodelc models plus the CLIP vocab.json + merges.txt — the exact layout Apples StableDiffusionPipeline (and the TokForge installer) loads.

Recommended render settings

attention:    split_einsum_v2 (Apple Neural Engine)
compute:      .cpuAndNeuralEngine  (palettized -> fast ANE compile)
steps:        25-30  (CyberRealistic photoreal sweet spot)
cfg-scale:    7.0
resolution:   512x512  (SD-1.5 native; baked into the compiled model)

How this was built

1. Loaded CyberRealistic_V9_FP16.safetensors from cyberdelia/CyberRealistic via diffusers StableDiffusionPipeline.from_single_file and re-exported to SD-1.5 diffusers format.
2. Converted UNet + text encoder + VAE decoder + VAE encoder to CoreML with Apple ml-stable-diffusion python_coreml_stable_diffusion.torch2coreml, --attention-implementation SPLIT_EINSUM_V2.
3. Applied 6-bit palettization (--quantize-nbits 6).
4. Bundled the compiled resources for the Swift CLI (--bundle-resources-for-swift-cli).

Conversion peaked at ~10.5 GB RAM (no --chunk-unet needed). Runs on iOS 17+ (6-bit palettized weights require the iOS-17 ANE runtime); on iOS-16 the app falls back to an FP16 model.

This repository is a redistribution for on-device use — a format conversion (PyTorch -> CoreML) and 6-bit palettization of cyberdelias CyberRealistic V9. No weights were retrained.
