<!-- Provide a quick summary of what the model is/does. -->

This is llama3 8b family chat model finetuned from base epfl-llm/meditron-7b with open assist dataset using SFT QLora .<br> All the linear parameters were made trainable with a rank of 16.<br>

Prompt template: Llama

'<s> [INST] <<SYS>>
You are a helpful, respectful and medical honest assistant. Always answer as helpfully as possible, while being safe. Your answers should not include any harmful, unethical, racist, sexist, toxic, dangerous, or illegal content. Please ensure that your responses are socially unbiased and positive in nature.
If a question does not make any sense, or is not factually coherent, explain why instead of answering something not correct. If you don't know the answer to a question, please don't share false information.
<</SYS>> {question} [/INST] {Model answer } </s>'

Usage:

model_name='jiviadmin/meditron-7b-guanaco-chat'

# Load the model
base_model = AutoModelForCausalLM.from_pretrained(
model_name,
low_cpu_mem_usage=True,

torch_dtype=torch.float16,
device_map={"": 0},
)
# Load tokenizer to save it
tokenizer = AutoTokenizer.from_pretrained(model_name, trust_remote_code=True,add_eos_token=True)
tokenizer.add_special_tokens({'pad_token': '[PAD]'})
tokenizer.pad_token_id = 18610
tokenizer.padding_side = "right"
