Realism By Stable Yogi SD 1.5 V9 LCM · Core ML 6-bit

This repository contains a reproducible Core ML format conversion for the LocalMuse iOS app. The original model was created by Stable Yogi. LocalMuseAI does not claim authorship of the source weights.

Source

• Model: Realism By Stable Yogi (Pony)
• Version: SD1.5_V9_LCM / Civitai version 1235013
• Source file: realismByStableYogi_sd15V9LCM.safetensors
• Source size: 2,132,626,090 bytes
• Source SHA-256: 1a16a9524427019dc513b398087035e7e36ad2f2aa9691bd71d28ad959e94180

The source is an already-distilled SD 1.5 LCM checkpoint. No additional LoRA or merge was applied during conversion.

Core ML conversion

• Fixed resolution: 512 × 512
• Runtime: Stable Diffusion 1.5, four-channel UNet
• Attention: SPLIT_EINSUM_V2
• Unet.mlmodelc: Apple 6-bit k-means palettization
• TextEncoder.mlmodelc: FP16
• VAEDecoder.mlmodelc: FP16
• VAEEncoder.mlmodelc: FP16
• Converter: Apple ml-stable-diffusion revision e12202c1f6405b83918b58a5d097cd61e3e1f702

All source files are authenticated before tracing. Component-level PyTorch/Core ML parity checks are enabled during conversion. Exact source and artifact hashes are recorded in PROVENANCE.json.

LocalMuse settings

• Scheduler: LCM
• Default: 9 steps
• CFG: 1.0
• Resolution: 512 × 512

The upstream gallery examples use Euler a at 9 steps and CFG 1. LocalMuse uses its existing LCM scheduler because this is an LCM-distilled checkpoint and the same configuration was validated before conversion. Upstream textual-inversion trigger names are separate assets and are not included in this repository.
