What is TRL?

TRL (Transformer Reinforcement Learning) is the standard Hugging Face library for fine-tuning language models. It supports supervised fine-tuning (SFT), reinforcement learning from human feedback (RLHF), direct preference optimization (DPO), and other alignment techniques. Built on top of Transfo...
