OpenAI Announces GPT-6 Astra as Its Most Advanced AI Model Amid Safety Concerns

OpenAI has announced the release of what it says is its most advanced AI model, amid heightened scrutiny of the risks of the frontier technology escaping human control.

The $852bn start-up said in its announcement on Thursday that GPT‑6 Astra, the “world’s most intelligent and aligned” AI model, earned perfect or near-perfect scores in key benchmarks of AI reasoning, beating both its prior release GPT 5.6 Sol and rival Anthropic’s Claude Fable 5.

The ChatGPT creator said GPT‑6 would become available to the general public in the coming days, following its initial launch with a “limited set of organisations”.

OpenAI’s latest release comes as the AI industry is at the centre of a lively public debate about the dangers of the cutting-edge technology following the AI-led hacking of the startup Hugging Face in July.

An independent probe into the cyberattack found that hundreds of OpenAI’s AI agents had begun communicating among themselves before breaking out of their controlled environment and compromising Hugging Face’s servers.

On Thursday, US Senator Bernie Sanders, an Independent, and US House Representative Greg Casar, a Democrat, unveiled legislation that would pause the development of advanced AI until the establishment of federal safety rules and an outright ban on the creation of “superintelligent” AI.

“Nearly every day, there is a frightening new story about how Big Tech companies are losing control of the technology they are developing, with potentially cataclysmic results,” Sanders said in a statement announcing the legislation, which is unlikely to advance due to the Republicans’ control of all three branches of the US government.

“The leaders of the major AI companies publicly acknowledge that they do not fully understand the technology and that it is escaping their control. It is irresponsible for society to allow them to move forward and make these products even more advanced.”

In its announcement, OpenAI devoted significant space to AI safety, highlighting both GPT‑6’s potential to do harm and its safety features.

Toby Walsh, a professor and AI expert at the University of New South Wales, Sydney, said that while OpenAI is clearly “neck and neck” in the race to lead AI, the technology remains inconsistent and in need of greater scrutiny.

“The intelligence in artificial intelligence is still today very jagged,” Walsh said. “There are simple things that even the best AI models do poorly.

“And it’s hard to see how the AI companies, including OpenAI, are slowing down to address justified concerns around cyber risk, when new models are being released at an ever greater and greater rate.”

Roman Yampolskiy, a computer scientist at the University of Louisville, said GPT‑6 marks a “meaningful” advance that raises the stakes for AI safety.

“The key question is whether capabilities are improving faster than our ability to reliably understand, predict and control these systems,” Yampolskiy said.

“I see little evidence that this gap is closing.”
