## AI overview

OpenAI describes how it is continuously hardening ChatGPT Atlas against prompt injection. Automated red teaming powered by reinforcement learning helps discover novel attacks and exploits so the browser agent's defenses can be improved before attacks spread in the wild.

## Source excerpt

OpenAI is strengthening ChatGPT Atlas against prompt injection attacks using automated red teaming trained with reinforcement learning. This proactive discover-and-patch loop helps identify novel exploits early and harden the browser agent's defenses as AI becomes more agentic.
