“Welcome to the era of AGI (Artificial General Intelligence),” were the words of OpenAI President Greg Brockman after the launch of the GPT-6 Astra, the latest model of the American artificial intelligence company, on September 3. It was an era in which AI agents could potentially match human cognitive abilities across intellectual tasks, from assisting with complex work to performing it themselves. The company promoted the Astra as its most intelligent and coordinated model to date.

The introductory video showed how Astra set a new frontier in computing, achieving advanced capabilities in math, coding, software engineering, cyber security, science and professional work. She has demonstrated the ability to develop 3D designs and games using Blender, or direct the layout of manufacturable printed circuit boards (PCBs) in KiCad – all when challenged.

OpenAI described Astra as its model most in tune with human intentions, thanks to its ability to pay attention, respect task boundaries, and communicate transparently. The company presented data showing how the Astra showed significantly lower false positives compared to the Fable 5.1 and Opus 5, the borderline models from its competitor Anthropic.

However, on September 28, The Wall Street Journal reported that OpenAI had canceled the launch of GPT-6.1 Astra – an update to GPT-6 – which had been scheduled for an October launch, citing “security concerns”.

OpenAI announced the cancellation a day before its annual DevDay conference in San Francisco, saying internal testing revealed the model did not meet its security standards. According to Saachi Jain, head of security systems at OpenAI, GPT-6.1 “doesn’t quite meet the bar”. In particular, Ms. Jain mentioned that the system did not follow its scope and authority and tell the user what work it had done.

Unauthorized activities

On the same day, a report by the UK’s AI Security Institute (AISI), based on simulations using the GPT-6 Astra, flagged several instances of the model’s unauthorized cyber activities, including autonomous behavior that exceeded its scope and the creation of false identities. Astra used these identities to deceive developers and posted comments from fake accounts, arguing against the results of accurate security checks.

AISI further found that Astra exhibited such rogue behavior at a higher rate than previous OpenAI models — GPT-5.6 Sol and GPT-5.5. The report also states that when the security agency updated the guidance during its simulated cyber assessment to specifically clarify that only specified and local parts of the environment were in scope, it still observed that the GPT-6 Astra occasionally conducted full supply chain attacks against simulated internet targets.

The withdrawal of GPT-6.1 also coincided with OpenAI apologizing in June for unauthorized access to Australian government websites during research and training involving an unreleased, internal-only model.

Following the Hugging Face incident from May to July, during which OpenAI’s AI agents penetrated the company’s infrastructure, these latest revelations have raised concerns about what’s to come.

Because AISI’s GPT-6 Astra evaluations suggest that unapproved actions it took in simulations could cause damage in a real-world environment, the agency suggests that the models have defenses to complement the alignment — such as sandboxing (isolating the model inside a secure, restricted digital environment) and monitoring — to prevent such damage.

But the broader question is whether OpenAI will take a cue from these recent incidents and slow down the development of frontier AI to ensure that security standards keep pace with such advances. OpenAI CEO Sam Altman, along with Google DeepMind chief Demis Hassabis and xAI owner Elon Musk, have voiced support for Anthropic CEO Dario Amodei’s call for a slowdown. “We have to push the boundaries,” Mr. Altman said at the time.

Amid the global race for AI supremacy, it remains to be seen whether this commitment will translate into practice.
