All Collections Team and Enterprise plans Security and compliance Data retention practices for Mythos-class models To ensure we’re responsibly deploying Mythos-class models, we are requiring limited data retention and review as part of our safety work. Prompts submitted to, and outputs generated by, Mythos-class models are retained for 30 days for trust and safety purposes, on every platform where these models are offered.

For more information on the threat model for retained data and associated privacy controls, please see the corresponding technical white paper on our Trust Center.…
