> There is a real danger that an LLM will include information in the summary that does not come from the original email thread, but from other emails the model was trained on. You could learn from the summary that you are going to get fired, even though that was not a part of the original conversation. HR doesn't like that. There could be separate personal fine-tunes per user, trained (in the cloud) on the contents of that user's mail database, which therefore have knowledge of exactly the mail that particular user can access, and nothing else. AFAICT this is essentially what Apple is claiming they're doing to power their own "on-device contextual querying."
