# mlx-community/Ming-Image-0.1-Design-Layer-4bit

Pre-quantized MLX tier of **[inclusionAI/Ming-Image-0.1-Design-Layer](https://huggingface.co/inclusionAI/Ming-Image-0.1-Design-Layer)** (MIT) for Apple
Silicon, loaded by the Swift/MLX port [ming-image-swift](https://github.com/xocialize/ming-image-swift). **4-bit tier** of the layer-decomposition model, for memory-bound Macs. It fits a 36 GB Mac, and the decompositions still match bf16.

A Mac never has to hold the bf16 weights to use this tier. Total size: 20.5 GB; the bf16 repo is 49.8 GB. It is
part of the [Ming-Image (MLX) collection](https://huggingface.co/collections/mlx-community/ming-image-mlx-6ab8008988cbe1b217f90c61), next to
[mlx-community/Ming-Image-0.1-Design-Layer-bf16](https://huggingface.co/mlx-community/Ming-Image-0.1-Design-Layer-bf16).

## What is quantized

| Component | This tier |
|---|---|
| `mllm/`: MoE MLLM (attention, dense and shared-expert MLPs, the 256 routed experts) | 4-bit |
| `connector/`: Qwen2-1.5B connector | 8-bit |
| `transformer/`: DiT attention and feed-forward | 8-bit |
| Kept at full precision: the MoE routers, embeddings, norms, the Qwen2.5 ViT, the f32 projection heads (`mlp/`), the VAE, and the DiT's conditioning layers (adaLN, embedders, final layer) | bf16 / f32 |

Weight-only affine quantization, group size 64. The DiT never goes below 8 bits: weight-only int4 on a DiT is
real quality damage that buys no speed.

The layout is the [bf16 repo's](https://huggingface.co/mlx-community/Ming-Image-0.1-Design-Layer-bf16) upstream tree, with MLX
`.scales` / `.biases` stored beside each quantized weight and a `quantization` block in each quantized component's
`config.json`. The Swift loader reads it as published. Loading this repo gives parameters bit-identical to
quantizing the bf16 snapshot at load time (verified for every parameter).

## Quality

| Gate: five real signage stills at 512, plus one at 1024 (same noise as bf16) | bf16 | 8-bit | **4-bit** |
|---|---|---|---|
| Layers recomposited vs the input | 24.4–33.7 dB | within 0.1 dB | **within 0.2 dB of bf16 on every job** |
| Layer coverage | — | identical | identical |
| Stray text outside the text layer (the hardest still) | 26 chars | 30 | 35 |

Full tables are in GATE-RESULTS §8 in the port's oracle (https://github.com/xocialize/ming-image-swift).

## Memory and speed

Measured on an M5 Max as process `phys_footprint`, with MLX's buffer cache capped at 2 GB (MLXEngine's default).

- Post-load resident: 7.6 GB. Peak process footprint: 20.0–20.6 GB for 4 to 12 layers at the 1024 bucket.
  At 12 layers the multi-frame denoise overtakes conditioning.
- MLXEngine declares 7.9 GB resident plus 15.6 GB activation, which is admitted on a 36 GB Mac. Requests are
  capped at 12 layers, the measured envelope.
- Speed (M5 Max, 12 steps, CFG 2.0): 134 s for 4 layers at the 512 bucket. bf16 takes 131 s.

## Use (Swift / MLXEngine)

```swift
import MLXMingImage
import MLXToolKit

let package = MingImageLayerPackage(configuration: MingImageLayerConfiguration(quant: .int4))
try await package.load()
let response = try await package.run(LayerDecomposeRequest(image: design, spec: spec, resolution: 1024)) as! LayerDecomposeResponse
```
