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 promptedOpenAI ⁠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.
