Here’s a question that keeps CISOs up at night: if OpenAI and Anthropic both promise not to train on your company’s data, why does sensitive corporate information keep ending up in AI models anyway?
The answer, it turns out, has less to do with the AI companies and more to do with Karen from accounting using her personal ChatGPT account to summarize confidential financial reports.
Both OpenAI and Anthropic have now made their enterprise privacy positions explicitly clear. OpenAI does not train models on data from ChatGPT Enterprise, Team, or EDU tiers by default. Anthropic offers the same guarantee for Claude Enterprise, Team, and Edu customers. Your corporate data stays your corporate data. On paper, problem solved.
The consumer account loophole
The critical distinction both companies draw is between enterprise and consumer tiers. And that distinction is where things get uncomfortable for businesses.
