Yup. I'm more paranoid about AI training on my chats than most ppl are. While I use frontier models to do research and to build tools, I've tried to avoid discussing details about my projects (e.g. story worldbuilding) except when using local models like Qwen-27B. Of course this slows down progress and has a real opportunity cost, but it would kill all my motivation if I got "scooped" like that.
