Model Card for Model ID

This model is an instruction-tuned Open LLaMa model with 7B parameters, with specialities in medical QA and code instruction.

Model Details

Model type: LlamaForCausalLM
Language(s) (NLP): English
License: Apache 2.0
Finetuned from model (QLoRA): openlm-research/open_llama_7b_v2

How to Get Started with the Model

Use the code below to get started with the model.

import torch
from transformers import LlamaTokenizer, LlamaForCausalLM

model_path = 'yhyhy3/open_llama_7b_v2_med_dolphin_qlora_merged'

tokenizer = LlamaTokenizer.from_pretrained(model_path)
model = LlamaForCausalLM.from_pretrained(
    model_path, torch_dtype=torch.float16, device_map='auto',
)

prompt = '''### Instruction: Answer the following question.

### Input: What is the capital of New Jersey?

### Response:'''
input_ids = tokenizer(prompt, return_tensors="pt").input_ids

generation_output = model.generate(
    input_ids=input_ids, max_new_tokens=32
)
print(tokenizer.decode(generation_output[0]))

Training Details

Training Data

Converted the following datasets to alpaca:instruction format.

ehartford/dolphin

ORCA style dataset generously created by Eric Hartford
Only used the 1 million GPT4 generated instructions file flan1m-alpaca-uncensored.jsonl.

LinhDuong/chatdoctor-200k

Refined dataset sourced from icliniq medical QA forum

sahil2801/code_instructions_120k

Code instruction dataset generously created by Sahil Chaudhary from ThreeSixty AI

medalpaca/medical_meadow_mediqa

MEDIQA is a dataset of manually generated, question-driven summaries of multi and single document answers to consumer health questions from medalpaca group.

kaiokendev/SuperCOT-dataset

Code instruction dataset generously created by Kaio Ken
