BioMedGPT-LM-7B

BioMedGPT-LM-7B is the first large generative language model based on Llama2 in the biomedical domain. It was fine-tuned from the Llama2-7B-Chat with millions of biomedical papers from the S2ORC corpus. Through further fine-tuning, BioMedGPT-LM-7B outperforms or is on par with human and significantly larger general-purpose foundation models on several biomedical QA benchmarks.

Training Details

The model was trained with the following hyperparameters:

• Epochs: 5
• Batch size: 192
• Context length: 2048
• Learning rate: 2e-5

BioMedGPT-LM-7B is fine-tuned on over 26 billion tokens highly pertinent to the field of biomedicine. The fine-tuning data are extracted from millions of biomedical papers in S2ORC data using PubMed Central (PMC)-ID and PubMed ID as criteria.
