Gausson/pythia-160m-deduped-n64-StreamingLLM

Please refer to the SepLLM paper - ICML 2025, StreamingLLM paper - ICLR 2024, and our GitHub repository 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. Below are the reference script for testing and a sample of test results. We conducted testing using lm_eval==0.4.0.
