SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

Axolotl provides a structured framework to fine-tune large language models using YAML-based configurations, enabling efficient experimentation with LoRA/QLoRA, DPO, ORPO, GRPO, and multimodal setups.

Core Features & Use Cases

  • YAML-driven fine-tuning workflows that simplify model customization and replication.
  • Support for LoRA/QLoRA adapters, DPO/ORPO/GRPO RLHF methods, and multimodal training pipelines.
  • Real-world use: teams can rapidly prototype fine-tuning strategies on instruction-following models and compare configurations with built-in memory and reference materials.

Quick Start

Install Axolotl and run a basic training config to begin fine-tuning an LLM.

FAQPage Schema
How do I fine-tune a large language model using YAML configurations?

Fine-tune a large language model using YAML configurations by defining training parameters, dataset paths, and adapter settings within a YAML file. This structured approach simplifies model customization and enables rapid replication of training experiments.

What is the best way to apply LoRA and QLoRA adapters for LLM training?

Apply LoRA and QLoRA adapters for LLM training by leveraging a framework that supports parameter-efficient fine-tuning. This enables rapid prototyping on instruction-following models while optimizing memory usage during experimentation.

Can I use DPO, ORPO, and GRPO for RLHF fine-tuning?

You can use DPO, ORPO, and GRPO for RLHF fine-tuning to align model outputs with human preferences. These methods are supported within the training pipeline to refine instruction-following capabilities and model behaviors.

Does the axolotl framework support multimodal training pipelines?

The framework supports multimodal training pipelines, allowing developers to fine-tune models that process multiple data types. This integration is driven by YAML-based configurations for structured experimentation and model customization.

Do I need deepspeed and accelerate to run axolotl fine-tuning?

You need deepspeed and accelerate to run fine-tuning efficiently. These dependencies, alongside torch and transformers, provide the distributed computing and memory optimization required for handling large language models.
