SAN FRANCISCO: ChatGPT maker OpenAI said on Thursday it would begin rolling out its newest and most powerful artificial intelligence (AI) model to select customers, saying it had built in safeguards to mitigate security risks.

“At this level of capability, safety has to become our top priority,” OpenAI President Greg Brockman told reporters on a call about the release of GPT-6, also known as Astra.

Just over a year has passed since OpenAI launched the previous version of its flagship model, GPT-5. Concerns about the capabilities of advanced models have grown since then, following incidents involving systems built by OpenAI and rival developer Anthropic.

OpenAI paused some model development for two weeks this summer after two models it was testing were involved in a security breach at AI platform Hugging Face.
