OpenAI, “GPTRed: Unlocking Self-Improvement for Robustness”

OpenAI introduced GPTRed, an internal automated red-teaming model trained through self-play to discover prompt-injection and agentic-system vulnerabilities and generate adversarial training data for production models. In an internal replication of a published prompt-injection challenge, GPTRed succeeded in 84% of novel scenarios versus 13% for human red-teamers; it also compromised a live autonomous vending agent by altering prices, ordering an expensive product at the minimum permitted price, and cancelling another customer’s order.
