What Is xTuring?

Claim this Tool

xTuring is an open-source AI personalization library built to help you customize large language models so they behave exactly as your application requires. It streamlines core steps like data preparation, fine-tuning, and evaluation through a user-friendly interface and clear documentation.

The framework focuses on efficiency, supporting low-resource fine-tuning via techniques such as Low-Rank Adaptation (LoRA), 8-bit precision, and related variants to reduce compute and memory costs. Example notebooks guide you through common workflows, from applying LoRA to evaluating model perplexity.

Backed by the Stochastic team and an active community, xTuring gives machine learning engineers, researchers, and developers a flexible way to adapt and extend LLMs for diverse use cases.
