Data sovereignty
What is a Private LLM?
A Private LLM is an artificial intelligence model that runs entirely on your own infrastructure—whether that's a powerful gaming laptop, an on-premise server, or a private cloud instance.
Unlike using public APIs like ChatGPT or Claude where your data is sent to external servers, a private LLM ensures your data never leaves your device. This allows businesses to process sensitive documents, proprietary code, and personal information with zero risk of data leakage or model training on your intellectual property.
