Summary

ArcticTraining is an open-source framework to simplify and accelerate LLM post-training. It addresses challenges like limited rapid prototyping support and lack of native synthetic data generation tools. By offering modular trainer designs, streamlined code, and integrated pipelines for synthetic data creation/cleaning, ArcticTraining empowers users to efficiently enhance LLM capabilities in code generation and complex reasoning, providing a flexible development experience.

How It Works

The framework emphasizes modularity and customization. Core components include modular trainer designs and simplified code structures for rapid iteration. A key differentiator is its integrated pipeline for native synthetic data generation and cleaning. Users can extend ArcticTraining by subclassing Trainer or SFTTrainer, allowing custom loss functions or training methodologies. This flexible design aims to boost LLM performance in tasks like code generation and complex reasoning with improved efficiency.

Quick Start & Requirements

Installation: pip install arctic-training. Training uses a YAML recipe file and the arctic_training CLI, leveraging DeepSpeed for distributed training. Customization involves modifying YAML or developing new trainers via subclassing. Further details are in the project's blog and documentation.
