SAN FRANCISCO, Sept 1 - OpenAI has determined ‌that one of its upcoming ‌models is so capable that it requires ​extra safety layers during its development and eventual release.

The company's internal testing showed that the model, ‌called Astra, ⁠is significantly more capable than the most advanced OpenAI ⁠model available to the public today, GPT-5.6 Sol, OpenAI officials said ​on Tuesday.

The ​ChatGPT maker ​is continuing to ‌navigate intense safety concerns after OpenAI-created agents broke out of their testing arena and hacked open-source platform Hugging Face. The incident prompted OpenAI ‌to pause much ​of its model ​development for ​two weeks to bolster ‌its defenses.

Astra wasn't involved ​in the ​Hugging Face incident, but its capabilities still require more careful ​measures, ‌OpenAI officials said.
