# ConvNeXt-Tiny
> Liu et al., 2022 — *A ConvNet for the 2020s* (arXiv:2201.03545)
[Lucid](https://github.com/ChanLumerico/lucid) port of `torchvision/ConvNeXt_Tiny_Weights.IMAGENET1K_V1`,
converted to Lucid-native safetensors.
## Available weights
| Tag | acc@1 | acc@5 | Params | GFLOPs | Size | Source |
|---|---|---|---|---|---|---|
| `IMAGENET1K_V1` *(default)* | 82.52 | 96.146 | 28.6M | 4.456 | 109.07 MB | torchvision |
## Usage
```python
import lucid.models as models
from lucid.models.weights import ConvNeXtTinyWeights
# default tag
model = models.convnext_tiny_cls(pretrained=True)
# explicit tag (enum or string)
model = models.convnext_tiny_cls(weights=ConvNeXtTinyWeights.IMAGENET1K_V1)
model = models.convnext_tiny_cls(pretrained="IMAGENET1K_V1")
# preprocessing travels with the weights
weights = ConvNeXtTinyWeights.IMAGENET1K_V1
preprocess = weights.transforms()
logits = model(preprocess(image)[None]).logits
```
## Conversion
Converted from `torchvision/ConvNeXt_Tiny_Weights.IMAGENET1K_V1` via
`python -m tools.convert_weights convnext_tiny --tag IMAGENET1K_V1`.
Key mapping + numerical parity verified against the source.
## License
`bsd-3-clause` — inherited from the original weights.
