Understand that nothing you prompt into an LLM is private. None of it. I made a video on the topic this week.
Just in the last year and a half there have been several massive public leaks of private data, on top of confusing functionality where people inadvertently shared their prompt data publicly. Now the major companies have human reviewers looking at your private stuff in order to make their LLM’s better at generating smut.
Do not enter anything into an LLM that you wouldn’t want plastered all over the public square. Some of this stuff has literally been leaked into global, public feeds.
