FAQPage Schema
How do I fine-tune LLMs with RLHF and align them with human preferences?▼

Fine-tune LLMs using TRL-based reinforcement learning to align models with human preferences. The workflow supports SFT, DPO, PPO/GRPO online RL, and reward-model training for end-to-end RLHF pipelines.

Can I use DPO and PPO for direct preference optimization with HuggingFace Transformers?▼

Yes, DPO and PPO are supported for direct preference optimization. The TRL suite integrates with HuggingFace Transformers to execute these reinforcement learning workflows for aligning base models.

What dependencies do I need to run a TRL fine-tuning pipeline?▼

Running a TRL fine-tuning pipeline requires the TRL suite, transformers, datasets, peft, accelerate, and torch. These dependencies execute production-grade reinforcement learning workflows.

How does supervised fine-tuning work for instruction tuning a base model?▼

Supervised fine-tuning (SFT) is supported for instruction tuning a base model. It serves as the initial step in the end-to-end RLHF workflow before applying preference alignment techniques.

Is GRPO supported for online reinforcement learning in TRL?▼

Yes, GRPO is supported for online reinforcement learning alongside PPO. The TRL suite facilitates these online RL methods and reward-model training to customize models for domain-specific tasks.

What is the best way to customize a base model for domain-specific instruction following?▼

The best way to customize a base model for domain-specific tasks is using TRL-based reinforcement learning. It leverages human feedback and evaluation through SFT, DPO, and PPO/GRPO workflows.
