High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I fine-tune LLMs with reinforcement learning using HuggingFace TRL?▼

Fine-tune LLMs with TRL by applying reinforcement learning to align model behavior with human preferences. It supports SFT, DPO, PPO/GRPO, and reward-model training across HuggingFace Transformers for instruction tuning and preference alignment.

What is the difference between SFT and DPO for preference alignment?▼

SFT performs instruction tuning to improve task performance, while DPO, PPO/GRPO, and reward-model training provide robust preference alignment. TRL orchestrates these methods to align model behavior with human preferences through distinct optimization workflows.

Do I need PEFT and accelerate to run TRL workflows?▼

Yes, TRL workflows require the ecosystem dependencies including trl, transformers, datasets, peft, accelerate, and torch. These libraries provide the necessary environment for running SFT and preference dataset training pipelines.

Can I use TRL for instruction tuning on custom domain-specific datasets?▼

Yes, TRL supports end-to-end RLHF pipelines with HuggingFace Transformers for custom domains and datasets. You can run instruction tuning and preference alignment using your own suitable SFT and preference datasets.

What is the best way to start with RLHF pipelines for chatbots?▼

Install TRL, prepare a small instruction-following dataset, and run a basic SFT fine-tune. This quick start approach demonstrates the end-to-end RLHF workflow for building chatbots and domain-specific assistants.

Why does TRL require both SFT and preference datasets?▼

TRL requires SFT datasets for initial instruction tuning and preference datasets for subsequent alignment. Both data types are necessary to execute the complete reinforcement learning workflow and optimize reward models effectively.
