# FLUX.1-dev — MLX quant matrix (bf16 / Q8 / Q4)

Pre-quantized, **MLX-ready** repackagings of [`black-forest-labs/FLUX.1-dev`](https://huggingface.co/black-forest-labs/FLUX.1-dev)
for the [SceneWorks](https://github.com/SceneWorks/SceneWorks) native Apple-Silicon worker (`mlx-gen`).
Each tier is a complete, self-contained turnkey snapshot that loads directly with no in-app
conversion peak (epic 8506).

| Tier   | Subdir  | Approx. size |
|--------|---------|--------------|
| Q4     | `q4/`   | ~8.7 GB |
| Q8     | `q8/`   | ~17 GB |
| bf16   | `bf16/` | ~31 GB |

All four components are packed in Q4/Q8 — the DiT transformer, the CLIP + T5 text encoders, and the
VAE's mid-block attention — using plain asymmetric group-affine quantization (group size 64),
byte-identical to the worker's load-time quantization. The bf16 tier is the dense source, mirrored.
