- Max Petrusenko points out that opting out of training data does not make ChatGPT or Claude sessions private: the vendor can still read your conversations.
- Less-guarded frontier models aren't freely available either — they come through approval programs: OpenAI's Trusted Access for Cyber and Anthropic's Cyber Verification Program.
- Practical takeaway for users handling sensitive workloads: privacy expectations and access to less-restricted models are both gated by vendor vetting.
