Training Open Instruction-Following Language Models

This repo serves as an open effort on instruction-tuning popular pretrained language models on publicly available datasets. We release this repo and will keep updating it with:

  1. Code for finetuning language models with latest techniques and instruction datasets in a unified format.
  2. Code for running standard evaluation on a range of benchmarks, targeting for differnt capabilities of these language models.
  3. Checkpoints or other useful artifacts that we build in our exploration.

Please see our first paper How Far Can Camels Go? Exploring the State of Instruction Tuning on Open Resources for more thoughts behind this project and our initial findings. Please see our second paper Camels in a Changing Climate: Enhancing LM Adaptation with Tulu 2 for results using Llama-2 models and direct preference optimization. We are still working on more models. For more recent results involving PPO and DPO please see our third paper Unpacking DPO and PPO: Disentangling Best Practices for Learning from Preference Feedback.

Setup

Our setup mostly follows our Dockerfile, which uses Python 3.10. Note that Open Instruct is a research codebase and does not guarantee backward compatibility. We offer two installation strategies:

pip install --upgrade pip "setuptools<70.0.0" wheel 
# TODO, unpin setuptools when this issue in flash attention is resolved
pip install torch==2.4.0 torchvision==0.19.0 torchaudio==2.4.0 --index-url https://download.pytorch.org/whl/cu121
pip install packaging
pip install flash-attn==2.6.3 --no-build-isolation
pip install -r requirements.txt
python -m nltk.downloader punkt
pip install -e .

docker build --build-arg CUDA=12.1.0 --build-arg TARGET=cudnn8-devel --build-arg DIST=ubuntu20.04 . -t open_instruct_dev
# if you are interally at AI2, you can create an image like this:
beaker image delete $(whoami)/open_instruct_dev 
beaker image create open_instruct_dev -n open_instruct_dev -w ai2/$(whoami)

If you are internally at AI2, you may launch experiments using our always-up-to-date auto-built image nathanl/open_instruct_auto.

Training

After having setup the environment, you are ready to launch some experiments. We provide a few examples below. To learn more about how to reproduce the Tulu 3 models, please refer to the Tulu 3 README. The instructions and documentations for Tulu 1 and Tulu 2 are in Tulu 1 and 2 README.

Finetuning

You can run the following commands for getting started:

# quick debugging run using 1 GPU
sh scripts/finetune_with_accelerate_config.sh 1 configs/train_configs/sft/mini.yaml
# train an 8B tulu3 model using 8 GPU
sh scripts/finetune_with_accelerate_config.sh 8 configs/train_configs/tulu3/tulu3_sft.yaml

Preference Tuning

# quick debugging run using 1 GPU
sh scripts/dpo_train_with_accelerate_config.sh 1 configs/train_configs/dpo/mini.yaml
# train an 8B tulu3 model using 8 GPU
sh scripts/finetune_with_accelerate_config.sh 8 configs/train_configs/tulu3/tulu3_dpo_8b.yaml

RLVR

# quick debugging run using 2 GPU (1 for inference, 1 for training)
# here we are using `HuggingFaceTB/SmolLM2-360M-Instruct`; it's prob not
# gonna work, but it's easy to test run and print stuff.

Contamination checks

We release our scripts for measuring the overlap between instruction tuning datasets and evaluation datasets in ./decontamination. See the README for more details.
