Model Card MELT-llama-2-7b-chat-v0.1
The MELT-llama-2-7b-chat-v0.1 Large Language Model (LLM) is a pretrained generative text model pre-trained and fine-tuned on using publically avalable medical data.
MELT-llama-2-7b-chat-v0.1 demonstrates a 31.4% improvement over llama-2-7b-chat-hf across 3 medical benchmarks including, USMLE, Indian AIIMS, and NEET medical examination examples.
Model Details
The Medical Education Language Transformer (MELT) models have been trained on a wide-range of text, chat, Q/A, and instruction data in the medical domain.
While the model was evaluated using publically avalable
USMLE, Indian AIIMS, and NEET medical examination example questions, its use it intented to be more broadly applicable.
Model Description
- Developed by: Center for Applied AI
- Funded by: Institute or Biomedical Informatics
- Model type: LLM
- Language(s) (NLP): English
- License: Apache 2.0
- Finetuned from model: llama-2-7b-chat-hf
Uses
MELT is intended for research purposes only. MELT models are best suited for prompts using a QA or chat format.
Out-of-Scope Use
MELT is intended for research purposes only and should not be used for medical advice.
Bias, Risks, and Limitations
MELT was training using collections publicly available, which likely contain biased and inaccurate information. The training and evaluation datasets have not been evaluated for content or accuracy.
How to Get Started with the Model
Use this model like you would any llama-2-7b-chat-hf model.
