# swin_small_patch4_window7_224

Converted TIMM image classification model for LiteRT.

- Source architecture: `swin_small_patch4_window7_224`
- Source checkpoint: `timm/swin_small_patch4_window7_224.ms_in22k_ft_in1k`
- File: `model.tflite`
- Input: `float32` tensor in NCHW layout, shape `[1, 3, 224, 224]`
- Output: ImageNet-1K logits, shape `[1, 1000]`

## Runtime Status

- CPU smoke test: passed with LiteRT `CompiledModel`.
- GPU delegation: currently blocked for this model by rank-5 tensor patterns in the GPU backend, mostly `RESHAPE`, `TRANSPOSE`, and related window/attention operations. The model is published as CPU-ready while GPU support is being improved.
