TRLX
Distributed RLHF training framework for LLMs
MIT
ABOUT
Reinforcement Learning from Human Feedback (RLHF) is critical for aligning LLMs with human preferences, but implementing it requires orchestrating multiple components — a policy model, a reference model, a reward model, and a value function — with PPO training loops that are notoriously difficult to scale. TRLX provides a production-ready, distributed RLHF pipeline that handles the complexity of multi-model training, credit assignment, and hyperparameter tuning so developers can focus on alignment, not infrastructure.
INSTALL
pip install trlxINTEGRATION GUIDE
1. Align a fine-tuned LLM with human preferences using PPO-based RLHF training
2. Train models with ILQL (Implicit Language Q-Learning) for offline preference optimization
3. Scale RLHF training across multiple GPUs and nodes for large 70B+ parameter models
4. Experiment with different reward models and preference datasets to optimize alignment
5. Fine-tune a language model to reduce harmful outputs while maintaining task performance
