Parameter Summary

Stored initializer elements includes weights, biases, quantization scales, zero-points, and other constant tensors. It is not a trainable-parameter count.

Original Model Inference

The original artifact is already ONNX, so the ONNX example below applies.

The upstream artifact is already ONNX. The model.onnx file above is the source-compatible downloadable model for this variant.
