TokForge — DreamShaper 8 · CoreML 6-bit (Apple Neural Engine)

A 6-bit palettized Apple CoreML conversion of DreamShaper 8 (Lykon, SD-1.5 realistic finetune), 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 — the ANE-fast beautiful default replacing the FP16 finetune that hit a >11-minute ANE graph compile.

Part of the TokForge iOS · CoreML Image Models collection.

File	Size	Contents
DreamShaper-8_palettized_split_einsum_v2_compiled.zip	~874 MB	The compiled Swift-CLI resource bundle (a single ZIP of Resources/)
Resources/	~913 MB	The unzipped tree: TextEncoder.mlmodelc / Unet.mlmodelc / VAEDecoder.mlmodelc / VAEEncoder.mlmodelc + vocab.json + merges.txt

The ZIP expands to one wrapper folder (Resources/) holding the compiled .mlmodelc models plus the CLIP vocab.json + merges.txt — the exact layout Apples StableDiffusionPipeline (and the TokForge installer) loads.

Recommended render settings (standard SD-1.5)

attention:    split_einsum_v2 (Apple Neural Engine)
compute:      .cpuAndNeuralEngine  (palettized -> fast ANE compile)
steps:        20   (8 = fast floor, 40 = extra refinement)
cfg-scale:    7.5
resolution:   512x512  (SD-1.5 native; baked into the compiled model)

How this was built

1. Loaded Lykon/dreamshaper-8 (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 (ANE-shaped attention).
3. Applied 6-bit palettization (--quantize-nbits 6) — the iOS-17 ANE runtime feature that makes the graph compile fast on the Neural Engine.
4. Bundled the compiled resources for the Swift CLI (--bundle-resources-for-swift-cli).

Conversion peaked at ~9.96 GB RAM (no --chunk-unet needed); runs on Apple silicon, iOS 17+ (6-bit palettized weights require the iOS-17 runtime).

This repository is a redistribution for on-device use — a format conversion (PyTorch -> CoreML) and 6-bit palettization of Lykons DreamShaper 8. No weights were retrained.
