Instruction Pre-Training: Language Models are Supervised Multitask Learners (EMNLP 2024)

This repo contains the finance model developed from Llama3-8B in our paper Instruction Pre-Training: Language Models are Supervised Multitask Learners.

We explore supervised multitask pre-training by proposing Instruction Pre-Training, a framework that scalably augments massive raw corpora with instruction-response pairs to pre-train language models. The instruction-response pairs are generated by an efficient instruction synthesizer built on open-source models. Instruction Pre-Training outperforms Vanilla Pre-training in both general pre-training from scratch and domain-adaptive continual pre-training. In pre-training from scratch, Instruction Pre-Training not only improves pre-trained base models but also benefits more from further instruction tuning. In continual pre-training, Instruction Pre-Training enables Llama3-8B to be comparable to or even outperform Llama3-70B.

Domain-Adaptive Continued Pre-Training

Following AdaptLLM, we augment the domain-specific raw corpora with instruction-response pairs generated by our context-based instruction synthesizer.

1. To chat with the finance-Llama3-8B model:

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("instruction-pretrain/finance-Llama3-8B")
tokenizer = AutoTokenizer.from_pretrained("instruction-pretrain/finance-Llama3-8B")

# Put your input here, NO prompt template is required
user_input = '''Use this fact to answer the question: Title of each class Trading Symbol(s) Name of each exchange on which registered
Common Stock, Par Value $.01 Per Share MMM New York Stock Exchange
MMM Chicago Stock Exchange, Inc.
1.500% Notes due 2026 MMM26 New York Stock Exchange
1.750% Notes due 2030 MMM30 New York Stock Exchange
1.500% Notes due 2031 MMM31 New York Stock Exchange

Which debt securities are registered to trade on a national securities exchange under 3M's name as of Q2 of 2023?'''

inputs = tokenizer(user_input, return_tensors="pt", add_special_tokens=True).input_ids.to(model.device)
outputs = model.generate(input_ids=inputs, max_new_tokens=400)[0]

answer_start = int(inputs.shape[-1])
pred = tokenizer.decode(outputs[answer_start:], skip_special_tokens=True)

print(pred)

2. To evaluate any Huggingface LMs on domain-specific tasks (💡New!)

You can use the following script to reproduce our results and evaluate any other Huggingface models on domain-specific tasks. Note that the script is NOT applicable to models that require specific prompt templates (e.g., Llama2-chat, Llama3-Instruct).

1). Set Up Dependencies

git clone https://github.com/microsoft/LMOps
cd LMOps/adaptllm
pip install -r requirements.txt

2). Evaluate the Model

# Select the domain from ['biomedicine', 'finance']
DOMAIN='finance'

# Specify any Huggingface LM name (Not applicable to models requiring specific prompt templates)
MODEL='instruction-pretrain/finance-Llama3-8B'

# Model parallelization:
# - Set MODEL_PARALLEL=False if the model fits on a single GPU. 
#   We observe that LMs smaller than 10B always meet this requirement.
# - Set MODEL_PARALLEL=True if the model is too large and encounters OOM on a single GPU.
MODEL_PARALLEL=False

# Choose the number of GPUs from [1, 2, 4, 8]
N_GPU=1

# Whether to add a BOS token at the beginning of the prompt input:
# - Set to False for AdaptLLM.
# - Set to True for instruction-pretrain models.
# If unsure, we recommend setting it to False, as this is suitable for most LMs.
add_bos_token=True

# Run the evaluation script
bash scripts/inference.sh ${DOMAIN} ${MODEL} ${add_bos_token} ${MODEL_PARALLEL} ${N_GPU}

FAQ on Continual Pre-Training from LLama3

Q1: Do you use the official Llama3 instruction prompt for pre-training?

No, the provided Llama3 instruction prompt is designed for the instruction-tuned model, but our continual pre-training is conducted on the pre-trained base model where only BOS (<|begin_of_text|>) and EOS (<|end_of_text|>) tokens are required.

Q2: For the general instructions from OpenOrca, do you concatenate each instruction with its output using '\n'?

No, as mentioned in the pre-training suggestions, we use a simple whitespace to concatenate each question with its response for the general instruction data from OpenOrca. This is because OpenOrca's data is already templated with diverse natural languge templates (such as those with \n), so a whitespace is sufficient to formulate the data.

Note that when using our templated instruction-augmented texts, you don't need to add any concatenations.

Q3: What about those system prompts in OpenOrca?

We simply discard the system prompts.

To put it all together, the text before tokenization looks like this:

general_instruction_response_text = "<|begin_of_text|>{question} {response}<|end_of_text|>"

instruction_augmented_text = "<|begin_of_text|>{instruction augmented text}<|end_of_text|>"

Then, for tokenization, you don't need to add BOS and EOS token ids. The tokenization code looks like this:

text_ids = tokenizer(text, add_special_tokens=False, **kwargs).input_ids
