4-step distillation decoder, packaged for SceneWorks' native (no-PyTorch) PiD
decoder (mlx-gen-pid on macOS/MLX, candle-gen-pid on Windows·Linux/CUDA).flux student serves the FLUX.1-dev VAE latent space — FLUX.1 (dev/schnell),
Boogu-Image (base/turbo/edit), Chroma (hd/base/flash), and Z-Image (turbo/edit),
which share that VAE.NSCLv1); see

|---|---|
pid_flux_2kto4k_v1pt5.safetensors | PiD v1.5 flux 2kto4k 4-step student (461 tensors, bf16, ~2.8 GB). Improved color fidelity, no grid-corner artifacts, better anime/face detail. The default for the 2kto4k (up-to-4K) output tier. |
pid_flux_2kto4k.safetensors | flux v1.0 2kto4k 4-step student backbone + sigma-aware LQ adapter (456 tensors, bf16, ~2.7 GB). Retained as the fallback for installs that predate v1.5. |
pid_flux_2k.safetensors | flux v1.0 res2k (2K-tuned) 4-step student. Sharper at 2048 px than the v1.5 2kto4k, so it serves the 2K output tier — NVIDIA ships no v1.5 res2k. |
