OpenAI releases new model that it says triggered internal security measures

OpenAI released its newest and most powerful model, called GPT-6 Astra, Thursday to a limited set of customers, labelling it the world’s most intelligent AI system and the first model to trigger advanced internal safety protections given its cyber capabilities.

The company said the model sets a new high-water mark for its ability to autonomously control computer systems and perform tasks on behalf of users, such as filling out spreadsheets and creating websites from scratch.

“Astra can really do anything a human can do with a computer,” OpenAI co-founder and president Greg Brockman said before the model was released.

“Astra is state-of-the-art on computer use, browser use, software engineering, cybersecurity, science, and professional work,” the company wrote in a blog post announcing Astra’s release.

The company also emphasized that the model is faster and more efficient than its predecessor, GPT-5.6 Sol, on a variety of tasks. For example, OpenAI said that Astra achieved a higher score using fewer output tokens, a common unit of measurement for AI tasks, on a key cybersecurity test called ExploitGym.

OpenAI said Astra would first be made available to participants in its Daybreak program for cybersecurity defenders, with wider access for enterprise and consumer accounts planned for the coming days.
