swinv2_tiny_window8_256

Converted TIMM image classification model for LiteRT.

• Source architecture: swinv2_tiny_window8_256
• FP32 file: model.tflite
• Static INT8 file: model_static_int8.tflite

Compatibility

The NPU entry denotes compilation support; runtime accuracy is unverified.

model_static_int8.tflite uses INT8 inputs/outputs and convolution/FC quantization; attention, normalization and other operations remain FP32. Apply the source checkpoint’s preprocessing, then quantize the input and dequantize the output using the file’s tensor scales and zero points.
