Companion artifact for [_GPU Forecasters: Language Models as Selective Surrogates for Kernel Runtime Optimization_](https://arxiv.org/abs/2605.31464). Code: [codezakh/gpu-surrogates](https://github.com/codezakh/gpu-surrogates). LoRA adapter for [`openai/gpt-oss-20b`](https://huggingface.co/openai/gpt-oss-20b) fine-tuned with the correctness reward to forecast kernel speedups. ## Loading ```python from peft import AutoPeftModelForCausalLM model = AutoPeftModelForCausalLM.from_pretrained("codezakh/gpu-forecasters-gpt-oss-20b-correctness") ``` ## Training data [`codezakh/gpu-forecasters-rl-training-pool`](https://huggingface.co/datasets/codezakh/gpu-forecasters-rl-training-pool). ## Reproducing See `runbook/02_train_surrogate.py` in the paper repo ([codezakh/gpu-surrogates](https://github.com/codezakh/gpu-surrogates)). ## Citation ```bibtex @article{khan2026gpuforecasters, title={GPU Forecasters: Language Models as Selective Surrogates for Kernel Runtime Optimization}, author={Khan, Zaid and Chen, Justin Chih-Yao and Cho, Jaemin and Stengel-Eskin, Elias and Bansal, Mohit}, journal={arXiv preprint arXiv:2605.31464}, year={2026} } ```
