SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires trl, transformers, datasets, peft, accelerate, torch, and includes references (resource) components.

What problem does it solve?

Implementing reinforcement learning from human feedback (RLHF) and LLM post-training alignment workflows requires coordinating multiple complex steps including supervised fine-tuning, reward model training, and policy optimization, with significant risk of errors like out-of-memory crashes, poor alignment quality, and incorrect hyperparameter configuration.

Core Features & Use Cases

  • End-to-end RLHF pipelines: Step-by-step guided workflows for full SFT → Reward Model → PPO alignment, with checklists for each stage.
  • Flexible preference alignment methods: Pre-built implementations for DPO, GRPO, and 10+ DPO loss variants for tuning models without separate reward models.
  • Production-ready resources: Ready-to-use training templates, deep-dive reference guides for reward function design and hyperparameter tuning, and troubleshooting for common training issues. Use case: For example, a developer can use this skill to align a base LLM to output structured XML-formatted reasoning and correct math answers using GRPO with custom reward functions, without implementing the training loop from scratch.

Quick Start

Use the fine-tuning-with-trl skill to align your base language model to follow custom response formatting and answer verification rules using GRPO training with custom reward functions.

FAQPage Schema
How do I implement RLHF and DPO workflows for LLM fine-tuning?▼

LLM fine-tuning with RLHF and DPO is streamlined using pre-built training pipelines and hyperparameter configurations that orchestrate supervised fine-tuning, reward modeling, and policy optimization without writing training loops from scratch.

What's the best way to align a base LLM to output structured responses using GRPO?▼

Aligning a base LLM with GRPO involves applying custom reward functions to enforce response formatting and answer verification rules, leveraging pre-built templates to guide the group-relative policy optimization process.

Do I need a separate reward model for direct preference optimization with Hugging Face tools?▼

Direct preference optimization with Hugging Face tools does not require a separate reward model, as DPO and GRPO methods apply preference alignment directly using over 10 loss variants to tune models efficiently.

How to troubleshoot out-of-memory crashes during PPO alignment training?▼

Troubleshooting out-of-memory crashes during PPO alignment relies on provided guidance for common training issues, offering hyperparameter tuning strategies and deep-dive references to stabilize the reinforcement learning process.

Can I use peft and accelerate for supervised fine-tuning before reward model training?▼

You can use peft and accelerate for supervised fine-tuning prior to reward model training, as the end-to-end RLHF pipelines integrate these dependencies to manage memory and distributed execution across the SFT stage.

What is the difference between DPO and GRPO for large language model alignment?▼

DPO and GRPO differ in their approach to large language model alignment, with DPO using preference loss variants and GRPO utilizing group-relative policy optimization with custom reward functions for structured tasks like math verification.
