OpenAI has begun rolling out Lockdown Mode, an optional security setting designed to protect users from prompt injection attacks. Lockdown Mode limits some features, including Deep Research and Agent Mode, but still allows image generation and file uploads. It is intended for people and organizations handling sensitive data.
