Please refer to the [SepLLM paper - ICML 2025](https://arxiv.org/abs/2412.12094) and our [`GitHub repository`](https://github.com/HKUDS/SepLLM)  for using this model.

To use the checkpoint of this model, you must install the `transformers-4.38.0.post1+sepllm-py3-none-any.whl` released from our [`GitHub repository`](https://github.com/HKUDS/SepLLM). Below are the reference script for testing and a sample of test results. We conducted testing using `lm_eval==0.4.0`.

```
CUDA_LAUNCH_BLOCKING=1
lm_eval --model hf \
	--model_args pretrained=Gausson/pythia-160m-deduped-n64-SepLLM \
	--tasks  arc_challenge,arc_easy,lambada_openai,logiqa,piqa,sciq,winogrande,wsc,wikitext  \
	--num_fewshot 5 \
	--device cuda:0\
	--batch_size 32
```
