# Krea 2 Onyx Turbo mlx 4bit

A **4-bit MLX quantization** of the official [`krea/Krea-2-Turbo`](https://huggingface.co/krea/Krea-2-Turbo), built for
on-device inference in the Onyx app with a documented, reproducible pipeline.

- **Source:** official `krea/Krea-2-Turbo` (diffusers fp16), quantized in-house.
- **Quantization:** 4-bit, group size 64, MLX. Only Linear leaves are quantized; norms / embeddings /
  convs / the VAE stay full precision. Components: `transformer/` (Krea2Transformer2DModel, 28 blocks +
  text-fusion), `text_encoder/` (Qwen3-VL), `vae/` (AutoencoderKLQwenImage), `tokenizer/`, `scheduler/`.
- **Inference:** distilled — ~8 steps, CFG off.
- **Verified:** reloaded through the Onyx engine and render-checked (coherent image, not noise) before publish.

This is a quantized derivative of Krea 2 for efficient on-device use; all credit for the model to Krea AI.
