New DPTrainer library adds differential privacy to Hugging Face Trainer without code changes
↗
DPTrainer lets developers apply differential privacy to Hugging Face Trainer workflows while keeping existing training code intact.
Engineers can train large language models on sensitive data with a provable privacy guarantee without rewriting their training loops. This reduces engineering effort and lowers the risk of silently breaking the privacy guarantee when integrating Opacus manually.

DPTrainer extends transformers.Trainer and introduces a PrivacyArguments dataclass to manage the differential privacy budget.
It integrates Opacus to perform per-sample gradient clipping, noise injection, and privacy accounting automatically.
Standard Trainer features such as callbacks, checkpointing, evaluation, and distributed training continue to work unchanged.
