Model Card for GPT-OSS-20b-bfloat16

This is OpenAI's gpt-oss-20b, but repackaged in Bfloat16 format, as the MXFP4 format of the original is only supported on Hopper and later architectures.

It contains no differences or further training compared to OpenAI's model, and you should read their model card for the details of the model.

It was primarily created by me to reduce the need to for repeated manual upcasting from MXFP4 to Bfloat16, which I was doing for running on older GPUs (such as on Kaggle or Colab) and for my fine-tuning experiments. You are, of course, welcome to use it too if it helps!
