## The problem
**Prompt injection** hides malicious instructions in web pages or files so an AI follows them, for example to leak data.

## What Lockdown Mode does
**Lockdown Mode** in **ChatGPT** disables:
- Live web browsing (cached content only).
- Retrieving and displaying web images (image generation still works).
- **Deep research** and **agent mode**.

OpenAI says it's "designed for people and organizations that handle sensitive data."

## Availability
Self-serve **ChatGPT Business** accounts and eligible personal accounts.

## Caveat
TechCrunch notes ChatGPT may still be vulnerable to prompt injection even with it on.
