+License: Must comply with license of Pythia since it's a model derived from Pythia.
+
+Sheared-Pythia-160m is a model pruned and further pre-trained from [EleutherAI/pythia-410m](https://huggingface.co/EleutherAI/pythia-410m). We dynamically load data from different domains in the Pile dataset to prune and contune pre-train the model. We use 0.4B tokens for pruning and 50B tokens for continued pre-training the pruned model. This model can be loaded with HuggingFace via
+
+model = GPTNeoXForCausalLM.from_pretrained("princeton-nlp/Sheared-Pythia-140m")
+
+The model's overall performance is better than EleutherAI/pythia-160m.
