Mosaic’s LLM Foundry is an open-source framework for training, fine-tuning, and deploying large language models (LLMs) efficiently. It provides scalable, optimized pipelines for every stage of the LLM lifecycle—from data preparation and model training to evaluation and inference—while integrating with modern acceleration tools like FlashAttention and distributed training strategies.

Features of Mosaic’s LLM Foundry:

Supports pre-training, fine-tuning, and inference of large language models with minimal configuration.
Integrates with advanced performance optimizations such as FlashAttention, FSDP, and tensor parallelism.
Compatible with Hugging Face tokenizers and model architectures.
Provides ready-to-use scripts and YAML configs for reproducible experiments.
Designed for both single-GPU setups and multi-node distributed clusters.
Open-source and actively maintained, making it suitable for both research and production.
