Xorbits Inference (Xinference) Project Description

What is the project about?

Xorbits Inference (Xinference) is a library designed for serving machine learning models, specifically focusing on large language models (LLMs), speech recognition models, and multimodal models. It aims to make model deployment and serving easy and efficient.

What problem does it solve?

Deploying and serving large, complex AI models can be challenging, requiring significant infrastructure and expertise. Xinference simplifies this process, allowing users to deploy and serve models with minimal effort, even with just a single command. It handles the complexities of hardware utilization, distributed deployment, and API management. It solves the problem of difficult and time-consuming model deployment.
