Product Overview
What is Unsloth AI?
Unsloth AI is an advanced open-source framework designed to dramatically speed up and simplify the fine-tuning of large language models (LLMs) such as Llama-3, Mistral, Phi-3, and Gemma. By manually optimizing compute-heavy mathematical operations and GPU kernels, Unsloth achieves up to 10x faster training on a single GPU and up to 32x on multi-GPU setups compared to traditional methods like Flash Attention 2. It supports NVIDIA GPUs from Tesla T4 to H100 and is portable to AMD and Intel GPUs. Unsloth reduces memory consumption by about 70%, enabling fine-tuning on more modest hardware like Google Colab or personal laptops. The platform offers a simple API, extensive documentation, and seamless integration with popular tools and inference engines, making it accessible for developers, researchers, and AI enthusiasts.
