ChatGPT

ChatGPT is OpenAI's consumer and enterprise chat assistant built on the GPT family of models. It handles writing, research, code generation, image and video creation (Sora), voice chat, file analysis, Deep Research, and agentic task execution via Agent Mode. It is the most widely adopted generative-AI product in the enterprise, available in Free, Go, Plus, Pro, Business, Enterprise, and Edu tiers. Business and Enterprise plans add SSO, admin controls, a signed DPA, SOC 2 Type II scope, and a contractual no-training default, while consumer tiers train on user data unless the user toggles it off.

The same vendor often carries very different risk depending on the plan. Free tiers typically allow training on prompts, paid tiers usually do not.

Storage

Stored in OpenAI-managed infrastructure (primarily AWS/Azure US); ChatGPT Enterprise and API offer regional data residency in the EU, UK, Japan, Korea, Singapore, India, Canada, and Australia.

Retention

Consumer tiers retain chat history until user deletes it (with 30-day soft delete), subject to ongoing legal hold. Business/Enterprise admins set retention. API Zero Data Retention is available for eligible endpoints and is required for the BAA.

Training on inputs

Consumer Free/Plus/Pro/Go default to training on user inputs unless opted out. ChatGPT Business, Enterprise, Edu, Healthcare, and the API do not train on customer data by default.
