TokForge — Realistic Vision 5.1 · CoreML 6-bit (Apple Neural Engine)

A 6-bit palettized Apple CoreML conversion of [Realistic Vision V5.1](https://huggingface.co/SG161222/Realistic_Vision_V5.1_noVAE) (SG161222, SD-1.5 photoreal finetune), built for on-device image generation in the [TokForge](https://tokforge.ai) iOS app. Converted with Apple [`ml-stable-diffusion`](https://github.com/apple/ml-stable-diffusion) (torch2coreml) using `SPLIT_EINSUM_V2` attention and `--quantize-nbits 6` — 6-bit palettized weights compile fast on the Apple Neural Engine (the ANE-fast photoreal path, vs the FP16 finetunes >11-min ANE graph compile).

Part of the [TokForge iOS · CoreML Image Models](https://huggingface.co/collections/darkmaniac7/tokforge-ios-coreml-image-models-6a38cca9b57803e6168ce232) collection.

Recommended render settings (standard SD-1.5, photoreal)

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 SG161222/Realistic_Vision_V5.1_noVAE (SD-1.5 diffusers; the diffusers conversion bundles a working VAE).
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) for the fast iOS-17 ANE compile.
4.Bundled the compiled resources for the Swift CLI (--bundle-resources-for-swift-cli).

Conversion peaked at ~10.9 GB RAM (no --chunk-unet needed); iOS 17+ (6-bit palettized).
