Unlimited text chats on the base model, subject to abuse guardrails, but limited file uploads, image creation, voice, deep research, memory and context, and Codex access. Advanced reasoning models, Projects, scheduled tasks, and custom GPTs are paid-tier features.

No standing free tier for Assistant. The Trial plan offers 100 searches and 100 Assistant interactions before requiring a paid plan, and still requires creating an account.

Conversations, Memories, and the account itself persist until the user deletes them. Once a deletion request is made, OpenAI states data is removed from its systems within 30 days, with exceptions where longer retention is required: fraud and abuse prevention, legal obligations, financial records for payments, and the audit trail of the deletion request itself. Temporary Chats are deleted automatically within 30 days unless a longer hold is needed for legal or safety reasons.

Conversation threads are automatically deleted after one day by default; a thread can also be deleted immediately by hand. A thread a user reports (for example, to flag a bug) is retained for 30 days before deletion for debugging purposes. Requests to the model backend are not saved or tied to a customer account by default, though Kagi notes they may be retained briefly as part of request debugging. On the model-provider side, retention varies by provider and is documented separately — see the Privacy Architecture section.
