OpenAI launches GPT-6 Astra for autonomous computer tasks
OpenAI has made a new AI system called GPT-6 Astra.
It is designed not only to answer questions but also to use a computer and complete tasks.
It can fill out forms, organise calendars, search the internet, write code, and make documents.
It can work through several steps without a person giving instructions after every action.
OpenAI says Astra performed very well on tests involving reasoning, computer use, coding, and cybersecurity.
The articles report slightly different scores for some of these tests.
OpenAI President Greg Brockman said Astra could be seen as part of the AGI era, although AGI is difficult to define.
The model may save people time, but its ability to find security weaknesses could also be misused.
Access initially goes to a limited group of organisations before expanding to more users.
OpenAI launched GPT-6 Astra on Thursday, September 3, calling it its most intelligent and aligned model.
Astra is designed to operate computers, browse websites, write code, manage documents, and complete complex multi-step workflows.
OpenAI reported strong benchmark results, though the articles differ slightly on its ARC-AGI and FrontierMath scores.
In OSWorld 2.0 latency simulations, Astra scored 72.6%, compared with 65.7% for GPT-5.6 Sol, while taking about 47% less time per task.
OpenAI said Astra improves task alignment but also reaches a critical cybersecurity capability threshold, creating possible misuse risks.
- Who
- OpenAI launched GPT-6 Astra, and OpenAI President Greg Brockman discussed its possible significance for AGI.
- What
- The company introduced an AI model built to reason, operate computers, write code, and complete multi-step professional tasks.
- When
- Thursday, September 3; the articles do not specify a year.
- Where
- The launch was described in OpenAI materials and a press briefing; no specific location was given. The model is being offered through OpenAI and AWS.
- Why
- OpenAI said Astra was developed to improve computer use, coding, research, cybersecurity, science, and professional workflows.
Potential Benefits
Safety Concerns
Work automation
Potential Benefits
Astra could automate administrative, research, software, legal, scientific, and creative workflows by using computers, documents, websites, and professional tools.
Safety Concerns
Delegating complex, real-world workflows to an autonomous system raises questions about human oversight and control.
Cybersecurity capability
Potential Benefits
The model could help developers identify vulnerabilities, troubleshoot software, and improve digital security.
Safety Concerns
OpenAI said Astra can identify vulnerabilities and develop exploits, including previously unknown vulnerabilities in some testing environments, creating potential misuse risks.
Artificial general intelligence
Potential Benefits
Greg Brockman said it was not unreasonable to view the technology as entering the AGI era and ended his briefing by welcoming that era.
Safety Concerns
Brockman acknowledged that AGI is a vague concept, and OpenAI did not formally declare that Astra had achieved AGI.
Alignment and autonomy
Potential Benefits
OpenAI said Astra better respects task boundaries; in one test it exceeded an authorised target in 0% of cases without production safeguards, compared with 48% for GPT-5.6 Sol.
Safety Concerns
The model’s ability to act independently across websites, software, and codebases means failures or misuse could have broader consequences.
