In today’s world, where data security and privacy have become fundamental issues, with the increasing use of language models in both private and business sectors, it is essential to start questioning the security and privacy that these tools can provide. The risk is that we might end up providing private or confidential information to companies that will use that data for training their models and for their purposes. ChatGPT, for instance, uses all chats to train its models, even in the paid version ChatGPT Plus at 25 EUR per month. The ChatGPT Team plans (25 EUR per month per user, minimum 2 users) and the APIs available to developers are excluded from the training.
