Introduction
MDCure is an effective and scalable procedure for generating high-quality multi-document (MD) instruction tuning data to improve MD capabilities of LLMs. Using MDCure, we construct a suite of MD instruction datasets complementary to collections such as FLAN and fine-tune a variety of already instruction-tuned LLMs from the FlanT5, Qwen2, and LLAMA3.1 model families, up to 70B parameters in size. We additionally introduce MDCureRM, an evaluator model specifically designed for the MD setting to filter and select high-quality MD instruction data in a cost-effective, RM-as-a-judge fashion. Extensive evaluations on a wide range of MD and long-context benchmarks spanning various tasks show MDCure consistently improves performance over pre-trained baselines and over corresponding base models by up to 75.5%.
We release MDCure datasets of size 12k, 36k, and 72k. We also release MDCureRM and the best MDCure'd model for each architecture/size combination. To access all our models and datasets, please visit our HF Collection. For further details regarding dataset construction, please see our paper and Github repo. For additional details regarding how to use yale-nlp/MDCure-Qwen2-1.5B-Instruct, please see below.
The MDCure pipeline generates diverse multi-document instructions, filters them via fine-grained scoring by MDCureRM, and tunes a base LLM to enhance its multi-document capabilities.
Model Details
yale-nlp/MDCure-Qwen2-1.5B-Instruct is initialized from Qwen/Qwen2-1.5B-Instruct and fine-tuned on the MDCure-72k dataset.
Requirements
We recommend using the latest version of HF Transformers, or any transformers>=4.45.0
, to avoid any potential errors when using this model.
Quickstart
Below we provide a code snippet demonstrating how to load the tokenizer and model and generate content in response to an input context concerning multiple source documents and a related question or instruction. We strongly recommend to separate the texts and/or instruction using \n\n
or <doc-sep>
to maintain consistency with the format of the data used during training.
model = AutoModelForCausalLM.from_pretrained("yale-nlp/MDCure-Qwen2-1.5B-Instruct", device_map='auto',torch_dtype="auto")
tokenizer = AutoTokenizer.from_pretrained("yale-nlp/MDCure-Qwen2-1.5B-Instruct")
source_text_1 = ...
source_text_2 = ...
source_text_3 = ...
prompt = f"{source_text_1}\n\n{source_text_2}\n\n{source_text_3}\n\nWhat happened in CHAMPAIGN regarding Lovie Smith and the 2019 defense improvements? Respond with 1-2 sentences."
messages = [
{"role": "system", "content": "You are an assistant with strong multi-document processing skills."},
{"role": "user", "content": prompt},
]
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)
generated_ids = model.generate(**model_inputs, max_new_tokens=512)
generated_ids = [output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)]
response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
print(response)
