+https://huggingface.co/JustinDu/BARTxiv with ONNX weights to be compatible with Transformers.js.
+
+## Steps to get ONNX quantized weights
+1. Use optimum-cli to convert the PyTorch weights to ONNX format.
+
+```bash
+optimum-cli export onnx --model JustinDu/BARTxiv BARTxiv_onnx
+```
+   
+2. Use the `quantize` script in the Transformers.js repo to quantize the ONNX weights.
+
+```bash
+python -m scripts.quantize --input_folder BARTxiv_onnx --output_folder BARTxiv_onnx/onnx
+```
+
+Move the `.onnx` files in the `BARTxiv_onnx` folder to `BARTxiv_onnx/onnx` (these are the FP32 weights).
