SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires litgpt, torch, transformers, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill provides clean, single-file implementations of over 20 Large Language Model (LLM) architectures, enabling users to easily implement, train, and fine-tune models for various applications.

Core Features & Use Cases

  • Model Implementation: Offers ready-to-use code for popular LLMs like Llama, Gemma, Phi, and Mistral.
  • Training & Fine-tuning: Supports full fine-tuning, LoRA, and QLoRA for efficient model adaptation.
  • Deployment: Includes tools for model quantization and conversion to formats like GGUF for deployment.
  • Use Case: A researcher wants to understand the internal workings of the Llama 3 model or fine-tune it on a custom dataset for a specific task. This Skill provides the necessary code and workflows.

Quick Start

Use the litgpt skill to fine-tune the microsoft/phi-2 model on a custom dataset located at data/my_dataset.json using LoRA.
