This model is generally better for accurate and informative responses, particularly for users seeking in-depth medical advice. The following YAML configuration was used to produce this model: ```yaml models: - model: Undi95/Llama-3-Unholy-8B parameters: weight: [0.25, 0.35, 0.45, 0.35, 0.25] density: [0.1, 0.25, 0.5, 0.25, 0.1] - model: Locutusque/llama-3-neural-chat-v1-8b - model: ruslanmv/Medical-Llama3-8B-16bit parameters: weight: [0.55, 0.45, 0.35, 0.45, 0.55] density: [0.1, 0.25, 0.5, 0.25, 0.1] merge_method: dare_ties base_model: Locutusque/llama-3-neural-chat-v1-8b parameters: int8_mask: true dtype: bfloat16 ``` # Comparision Against Dr.Samantha 7B | Subject | Medichat-Llama3-8B Accuracy (%) | Dr. Samantha Accuracy (%) | |-------------------------|---------------------------------|---------------------------| | Clinical Knowledge | 71.70 | 52.83 | | Medical Genetics | 78.00 | 49.00 | | Human Aging | 70.40 | 58.29 | | Human Sexuality | 73.28 | 55.73 | | College Medicine | 62.43 | 38.73 | | Anatomy | 64.44 | 41.48 | | College Biology | 72.22 | 52.08 | | High School Biology | 77.10 | 53.23 | | Professional Medicine | 63.97 | 38.73 | | Nutrition | 73.86 | 50.33 | | Professional Psychology | 68.95 | 46.57 | | Virology | 54.22 | 41.57 | | High School Psychology | 83.67 | 66.60 | | **Average** | **70.33** | **48.85** | The current model demonstrates a substantial improvement over the previous [Dr. Samantha](sethuiyer/Dr_Samantha-7b) model in terms of subject-specific knowledge and accuracy. ### Usage: ```python import torch from transformers import AutoTokenizer, AutoModelForCausalLM class MedicalAssistant: def __init__(self, model_name="sethuiyer/Medichat-Llama3-8B", device="cuda"): self.device = device self.tokenizer = AutoTokenizer.from_pretrained(model_name) self.model = AutoModelForCausalLM.from_pretrained(model_name).to(self.device) self.sys_message = ''' You are an AI Medical Assistant trained on a vast dataset of health information.

What is the differential diagnosis? ''' response = assistant.generate_response(question) print(response) ``` ## Ollama This model is now also available on Ollama. You can use it by running the command ```ollama run monotykamary/medichat-llama3``` in your terminal.
