LLMs should be free, and private data is the core of the next evolution for models. This applies to both personal and enterprise applications. The next step for models is to figure out how to obtain more private data from users. The difference between PC and mobile is that on mobile, each app should be independently authorized due to system restrictions, but on PC, LLMs can be authorized to access more data. I'm not sure if OpenAI's Codex or Anthropic's Claude have backdoors to access your private data on the PC side.
