mlx-community/Boogu-Image-0.1-Base-4bit

MLX (int4) conversion of Boogu-Image-0.1-Base (Apache-2.0) for Apple Silicon — bilingual (EN/ZH) text-to-image. OmniGen2-lineage pipeline (DiT + FLUX.1 VAE + FlowMatchEuler scheduler). The Qwen3-VL-8B-Instruct text encoder is the stock model (verified bit-identical) — referenced from mlx-community/Qwen3-VL-8B-Instruct, not re-hosted.

Quantization: attn+FFN Linears int4 (group_size=32); per-pass cosine vs bf16 0.99896. ~7.4 GB. Quant auto-detected via transformer/quant_config.json.

Parity (CPU stream, fp32)

• FLUX VAE decode: max_abs 6.7e-6 · encode 1.97e-4
• Scheduler (flow-match + time-shift): bit-exact
• Full DiT (40-layer): max_abs 1.56e-5
