FAQPage Schema

How do I fine-tune a large language model with RLHF and DPO?▼

This skill optimizes language models through post-training alignment techniques including SFT, DPO, RLOO, and GRPO to align outputs with human preferences. It creates reward-driven RLHF pipelines for instruction-following models.

What is the best way to train LLMs with minimal VRAM using GRPO?▼

GRPO implements memory-efficient reinforcement learning to train large language models with minimal VRAM requirements. It enables reward-driven RLHF pipelines by optimizing model alignment without exhausting hardware resources.

Do I need transformers and peft to run RLHF pipelines?▼

Yes, executing RLHF training workflows requires integration with transformers, datasets, peft, and accelerate libraries to process data and manage memory-efficient reinforcement learning for instruction-following models.

Can I use DPO to align a Qwen base model with human preferences?▼

Yes, you can take a base model like Qwen and fine-tune it to follow specific reasoning formats or align it with human-rated preference datasets using DPO and other post-training alignment pipelines.

How do I start a reinforcement learning pipeline with a reward model?▼

To start a reinforcement learning pipeline, run the trl rloo command with your base model and reward model paths. This initiates the RLOO training workflow for aligning your language model.
