PiD — Pixel Diffusion Decoder (qwenimage 2kto4k student)
=========================================================

This repository redistributes a converted copy of a model checkpoint
originally produced and released by NVIDIA Corporation.

Original work

  Name:     PiD (Pixel Diffusion) — PixelDiT distillation decoders
  Author:   NVIDIA Corporation and its affiliates (NVIDIA Toronto AI Lab)
  Source:   https://huggingface.co/nvidia/PiD

  Paper:    arXiv:2605.23902
  Original checkpoint:
            checkpoints/PiD_res2kto4k_sr4x_official_qwenimage_distill_4step/model_ema_bf16.pth

What was changed
----------------
  The original PyTorch checkpoint (`model_ema_bf16.pth`) was converted to
  safetensors format for use by SceneWorks' native MLX/candle PiD decoder
  (`mlx-gen-pid`). The conversion is a lossless key/format transform only:
  training-only tensors (`net_ema.*`, `fake_score.*`, `discriminator.*`) are
  dropped and the `net.` prefix is stripped, per the reference inference
  loader (`pid_distill_model.py::PidDistillModel.load_state_dict`). Tensor
  values and dtype (bfloat16) are unchanged. No re-training or fine-tuning
  was performed.
