Unsloth AI
Open-source platform for fine-tuning and reinforcement learning of large language models (LLMs).
About Unsloth AI
Unsloth simplifies training text-to-speech (TTS), diffusion, multimodal, and language models like Llama 3, entirely locally or for free on platforms such as Google Colab and Kaggle. It handles the full training workflow—from model loading and quantization to evaluation, deployment, and integration with inference tools like Ollama, llama.cpp, and vLLM—making advanced AI development accessible and efficient.
How to Use
Unsloth can be installed on Linux, Windows, or via cloud services like Google Colab and Kaggle. Most users access it through Google Colab’s free GPU environment for seamless training and experimentation.
