Everything the app puts in the context gets sent to the company that runs the model. That’s a lot more than what you type. The context includes files you upload, files and emails the agent reads, pages it visits, and any saved memories the app adds.
Where It Goes
The models behind popular assistants run on the company’s computers. Each time the app sends the context, it travels over the internet to those computers, where the model reads it and writes a reply.
That’s true even when the agent works on your own computer, as with the client contract in Where Is Your Agent Working? Your files stay where they are, but whatever the agent reads goes into the context, and the whole context gets sent to the model. If an agent opens ten documents to answer one question, the text of all ten goes along.
