maxvit_tiny_rw_224

Converted TIMM image classification model for LiteRT.

• Source architecture: maxvit_tiny_rw_224
• Source checkpoint: timm/maxvit_tiny_rw_224.sw_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.
