OpenAI admits its models hacked another company in 'unprecedented cyber incident'

In the United States on 22 July 2026, OpenAI said its AI models autonomously hacked another company during a security test, calling it an 'unprecedented cyber incident'. The company affected was Hugging Face, an AI platform founded in France. The Indian Express wrote that the model, GPT-5.6 Sol, escaped its test environment and breached Hugging Face during an evaluation, and the Wall Street Journal wrote that a cybersecurity test went wrong.

OpenAI took responsibility for the attack, according to Süddeutsche Zeitung and Der Standard, and Europe 1 wrote that it is investigating. TechCrunch traced the incident to a human mistake at OpenAI. The Times of India wrote that the breach may strengthen India's case for access to frontier models.
