OpenAI chases Anthropic's biz customers with zero data retention pledge

OpenAI appears to have found a way to balance AI model safety with commitments to retain no customer data, a feat rival Anthropic hasn't yet managed.

For orgs concerned about who has access to their data, this could be a game-changer.

The free-spending AI biz on Wednesday announced Private Safety Processing, a mechanism for automatically scanning customer model interactions for safety risks without violating Zero Data Retention (ZDR) commitments.

Anthropic meanwhile has noted that its implementation of ZDR includes a non-zero amount of data retention for covered models – currently Mythos 5 and Fable 5.

For commercial customers using ZDR as of June 9, 2026, "we are requiring limited data retention and review as part of our safety work.

Prompts submitted to, and outputs generated by, covered models are retained for 30 days to support our safety work, on every platform where these models are offered." OpenAI, Anthropic, and various other AI model makers agree some oversight of rapidly advancing model capabilities is a good idea.

The devil is in the details, which in the case of Private Safety Processing have not yet been published.

Generally speaking, both companies have similar policies for commercial customers using lower tier models.

"For Anthropic API users, we automatically delete inputs and outputs on our backend within 30 days of receipt or generation," Anthropic says, with exceptions for certain services, ZDR agreements, and legal/policy enforcement.

For OpenAI ChatGPT Business customers, "Your workspace admins can control how long your data is retained.

Any deleted or unsaved conversations are removed from our systems within 30 days, unless longer retention is required by law, or is reasonably necessary to protect our services or any third party from harm." That 30-day policy also applies to OpenAI's API in most cases.

When Anthropic detects usage violations, it may retain model inputs and outputs for up to two years and trust and safety classification scores for up to seven years.

The major distinction now is ZDR and how the two frontier AI companies define that concept.

Anthropic has a ZDR exception for those using its top models.
