OpenAI’s GPT-Red automates prompt injection testing to harden AI agents
The New Stack Amanda Caswell ● Covered by 3 sources
OpenAI unveiled GPT-Red, an automated red-teaming system that uses AI to find prompt injection vulnerabilities in AI agents by testing thousands of exploit variations. GPT-5.6 achieved six times fewer failures on prompt-injection benchmarks than the strongest production model released four months earlier, and GPT-Red successfully manipulated a live vending machine agent to discount items over $100 to $0.50. The result shifts security testing from manual human discovery to continuous automated adversarial probing integrated into model training pipelines.
