This repo contains the code for our paper ScaleBiO: Scalable Bilevel Optimization for LLM Data Reweighting. In this work, we introduce ScaleBiO, the first scalable instantiation of first-order bilevel optimization algorithm, focusing on large-scale LLM data reweighting.

• [2024-07-30] Preview version - we release the demo data reweighting code and data for gpt2 and Yi-34B on alpaca and alpaca-gpt4 dataset.

pip install -r requirements.txt

export WANDB_API_KEY=<your_wandb_api_key> and turn on --use_wandb in the script

./run_gpt2.sh

./run_Yi34B.sh

8x A40/A100 GPUs and 2TB Memory
