From the publisher at commit 335a523. Shown as plain text with links; images open at the publisher.

https://huggingface.co/nvidia/OpenMath-Nemotron-1.5B with ONNX weights to be compatible with Transformers.js.

Note: Having a separate repo for ONNX weights is intended to be a temporary solution until WebML gains more traction. If you would like to make your models web-ready, we recommend converting to ONNX using 🤗 Optimum and structuring your repo like this one (with ONNX weights located in a subfolder named onnx).
