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, production-ready implementations for over 20 Large Language Models (LLMs) using Lightning AI's LitGPT, enabling efficient training, fine-tuning, and deployment.

Core Features & Use Cases

  • Model Implementation: Access single-file, readable code for architectures like Llama, Gemma, Phi, Mistral, and Qwen.
  • Fine-Tuning: Easily fine-tune models on custom datasets using full fine-tuning or efficient LoRA/QLoRA methods.
  • Deployment: Convert and deploy models for inference using FastAPI or other frameworks.
  • Use Case: You need to fine-tune a Llama 3 model on your company's internal documentation to create a specialized chatbot. This Skill provides the exact code and training scripts to achieve this efficiently.

Quick Start

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

FAQPage Schema
How do I fine-tune a Llama model on a custom dataset using LoRA?

Fine-tune a Llama model on custom datasets using LitGPT by applying parameter-efficient LoRA or QLoRA training scripts. LitGPT provides readable, single-file implementations for over 20 architectures, enabling efficient adaptation of pretrained LLMs to your specific data.

What is the best way to implement and train LLMs like Llama and Mistral in PyTorch?

Implementing and training LLMs like Llama and Mistral in PyTorch is streamlined using the LitGPT framework. It provides production-ready, single-file code for over 20 architectures, supporting pretraining from scratch and full or LoRA fine-tuning workflows.

Can I use LitGPT to pretrain a large language model from scratch?

Yes, LitGPT supports pretraining large language models from scratch. The framework provides training scripts and model implementations for architectures like Phi, Qwen, and Gemma, allowing you to build custom foundational models using PyTorch and Transformers.

Does LitGPT support model conversion for deployment with FastAPI?

LitGPT supports model conversion and deployment for inference using frameworks like FastAPI. After fine-tuning or pretraining, you can convert your LLM and deploy it for production inference, bridging the gap between training and live application serving.

What pretrained architectures are supported by LitGPT for custom fine-tuning?

LitGPT supports over 20 pretrained architectures for custom fine-tuning, including Llama, Gemma, Phi, Qwen, and Mistral. This allows you to select the most suitable base model for your specific domain and training requirements.

Why use LitGPT over standard Transformers for LLM implementation?

LitGPT offers clean, single-file implementations for LLM architectures, making the code more readable and modifiable than standard Transformers. It provides integrated workflows for LoRA fine-tuning and pretraining, streamlining the process of training and deploying models.
