Large Language Models Are Reasoning Teachers

Official repository for Large Language Models Are Reasoning Teachers, by Namgyu Ho, Laura Schmid, and Se-young Yun.

🚀 Accepted to ACL 2023.

This repository contains code for (1) running CoT reasoning on OpenAI models, and (2) apply Fine-tune-CoT to train students based on OpenAI models or custom open-source models such as T5, Flan-T5, GPT-2 on your GPUs, based on 🤗 and Pytorch Lightning.

Getting Started

OpenAI API Experiments

OpenAI API experiments are implemented in the oai module. Refer to notebooks/example_oai_finetune_cot.ipynb on how to run Fine-tune-CoT from start to finish.

Custom Experiments (on GPU)

Custom experiments are implemented in the custom module, based on PyTorch Lightning. Refer to main.py and scripts/custom/*.sh on how to fine-tune models such as T5, Flan-T5, and GPT-2 using Fine-tune-CoT.

Setup

pip install -r requirements.txt
python setup.py develop

Data 🚀

We're proud to share all of our raw experimental data! All data is organized in json or jsonl format, for your pleasure :)

• Dropbox
• Google Drive

File List

• dataset.tar.gz: 12 task datasets compiled in a unified json format
  • Belongs in PROJECT/data/dataset/
• completion_data.tar.gz: Completion data, i.e., inference data, from all teachers and students, for all experiments. About 8GB when uncompressed
  • Belongs in PROJECT/saved/completion_data/
• teacher_completion_data.tar.gz: Completion data from Zero-shot-CoT (with diverse reasoning) on the default teacher model text-davinci-002 using the OpenAI API. About 💰 $1000+ worth of goods, with ❤️ from OSI LAB at KAIST . Subset of completion_data.tar.gz.
  • Belongs in PROJECT/saved/completion_data/.
• finetune_data.tar.gz: All data used to fine-tune OpenAI students via the fine-tuning API, in jsonl format. These are derived from teacher completion data and can be generated from our code.
  • Belongs in PROJECT/saved/finetune_data/

Generate Paper Results

After downloading the full completion_data.tar.gz, you can run notebooks/results.ipynb to generate all result tables and figures from our paper. The code will (re-)evaluate all raw text model outputs contained in the completion data.
