YOLO26l-OptiQ-6bit
Mixed-precision quantized YOLO26l for Apple Silicon via optiq
This is a mixed-precision quantized version of YOLO26l in MLX format, optimized with mlx-optiq for Apple Silicon inference via yolo-mlx.
Quantization Details
| Property | Value |
|---|---|
| Target BPW | 6.0 |
| Achieved BPW | 6.00 |
| Layers at 4-bit | 16 |
| Layers at 8-bit | 174 |
| Original size | 100.7 MB |
| Quantized size | 22.9 MB |
| Compression | 4.4x |
Benchmark Results (COCO128)
| Model | Total Detections | Avg/Image |
|---|---|---|
| optiq 6-bit | 766 | 6.0 |
| Original (FP32) | 766 | 6.0 |
Detection delta: +0 (+0.0%) at 4.4x compression.
Usage
Requires mlx-optiq and yolo-mlx:
pip install mlx-optiq yolo-mlx
from optiq.models.yolo import load_quantized_yolo
model = load_quantized_yolo("mlx-community/YOLO26l-OptiQ-6bit")
results = model.predict("image.jpg")
How optiq Works
optiq measures each conv layer's sensitivity via KL divergence on detection outputs, then assigns optimal per-layer bit-widths using greedy knapsack optimization. Sensitive layers (detection head, feature pyramid) get 8-bit precision while robust backbone layers get 4-bit.
