Unlocking Self-Improvement: How GPT-Red Automates Prompt Injection Defense to Forge GPT-5.6 Sol
Introduction As artificial intelligence systems transition from passive query-response interfaces to active, tool-enabled autonomous agents, they must interact directly with unpredictable third-party environments. While features like local file access, web browsing, and external API integrations greatly increase capability, they also expand the attack surface, leaving systems vulnerable to sophisticated, multi-stage exploits hidden in external data. Traditional manual security evaluation, commonly known as red-teaming, has historically served
