MOSS-Image-SFT (8-bit) for Apple Silicon (MLX / mflux)

Native Apple Silicon implementation of MOSS-Image-SFT ported to Apple MLX via mflux.

  • Precision: 8-bit (High-Fidelity -47.2% VRAM)
  • Model Size: Transformer 5.03 GB
  • Architecture: 42-layer MOSS-Image DiT Transformer + Qwen 3.5 Text Encoder + FLUX.2 Small VAE
  • Native Apple Silicon Support: Metal Performance Shaders (MPS) & Unified Memory

3-Precision Comprehensive Benchmark (Tested on Apple M3 Max)

Precision Transformer VRAM Compression 1024² Step Time Fidelity Engineering Recommendation
BF16 9.52 GB Baseline (100%) ~13.9 s / step ⭐⭐⭐⭐⭐ 100% Master production / Highest detail
8-bit 5.03 GB -47.2% ~17.1 s / step ⭐⭐⭐⭐⭐ 99.8% 👑 Recommended for Daily Production
