AI Prompt Injection Vulnerability

OpenAI developed GPT-Red, an LLM-based red-teaming tool, to autonomously discover and exploit vulnerabilities, particularly prompt injections, in its large language models. Through self-play training, GPT-Red enhanced defensive capabilities by finding novel attack vectors like "fake chain of thought" injections, significantly improving model robustness.
