FAQPage Schema

How do I fine-tune a large language model with reinforcement learning using HuggingFace transformers?▼

The framework supports SFT, DPO, PPO, and GRPO workflows for comprehensive post-training alignment. These methods enable preference alignment and instruction following without requiring manual, ad-hoc fine-tuning processes.

Can I use this to align a base model like Qwen to follow complex reasoning chains?▼

Yes, this framework supports the creation of custom reward models to score model generations based on specific criteria. This enables tailored reinforcement learning workflows for specialized alignment tasks.

What dependencies do I need to run RLHF workflows for language model alignment?▼

Supervised fine-tuning (SFT) is used for initial instruction tuning on your instruction dataset. Direct Preference Optimization (DPO) is then applied for preference alignment without needing a separate reward model.

What is the difference between PPO and GRPO for RLHF post-training?▼

You can start a supervised fine-tuning run by using the SFTTrainer class on your instruction dataset. This provides the foundational instruction following behavior before applying further preference alignment techniques.
