Why a private AI solution?
Commercial AI services such as ChatGPT and MidJourney are Software as a Service solutions to generate, rewrite or optimise texts and images. They work with paid subscriptions. The services themselves work like a black-box. You don't know what happens to the data you enter.
Companies and organisations working with trade secrets and/or privacy-sensitive information cannot use such AI solutions.
A possible solution is to use Open Source Large Language Models, hosted on your own servers or on your own private cloud hosting.
