# OpenAI built an AI super-hacker to break its own models GPT-Red model automates AI security testing at machine speed. - **Source:** [The Next Web](https://brifing.si/source/afe24b20-b275-4c19-b9a6-8bb3c8babae7) - **Published:** 2026-07-15 - **Topic:** [Data & AI](https://brifing.si/c/data-ai) - **Original article:** - **On Brifing:** https://brifing.si/s/d40d8e96-80a8-4476-bb16-250281d74f08 ## The AI Super Hacker OpenAI developed an AI model called GPT-Red, designed specifically to find security vulnerabilities in its other AI systems. This automated red-teamer detects attack methods like prompt injection, helping to enhance model security before deployment. ## Self-Learning System GPT-Red learns by continuously battling defense models. Rewarded for successful attacks, it develops increasingly sophisticated methods as defenses improve. OpenAI invested unprecedented computational resources into this safety research project. ## Discovered New Attack Vectors GPT-Red uncovered a novel attack type called 'fake chain of thought,' which plants false information in a model's working memory to make it trust fabricated data. OpenAI researchers had never encountered this attack method before. ## Tested in Physical World Beyond digital tests, GPT-Red successfully hacked Vendy, an AI agent controlling a real vending machine in OpenAI's office. It manipulated prices and canceled orders, demonstrating real-world security vulnerabilities in AI systems. ## Outperformed Human Testers In 2025 testing, GPT-Red surpassed human red-team members, solving 84% of scenarios compared to humans' 13% success rate. However, the model still has weaknesses in prolonged attacks and image-based exploits, requiring ongoing human oversight. ## Future Security Standard While keeping GPT-Red restricted to prevent misuse, OpenAI is setting new benchmarks in AI security. The company aims to use current models to harden future systems, creating a safety flywheel that scales with AI capabilities. ## Sources covering this story - https://thenextweb.com/news/gpt-red-openai-ai-hacker — --- _Summary written by Brifing from the original reporting.
