OpenAI has released GPT-6 Astra, a new flagship model arriving less than two months after its GPT-5.6 family, which the company calls its most intelligent and aligned system yet. Astra is built to handle multi-step computer-use tasks, coding, browsing and professional workflows simultaneously, and OpenAI backs the claims with strong scores on benchmarks like ARC-AGI-3, Terminal Bench 4.0, and the Agent's Last Exam.
OpenAI has rolled out GPT-6 Astra, calling it the most capable model it has ever deployed, with major upgrades in software engineering, computer/browser use, and cybersecurity. Astra is the first OpenAI model to reach the company's 'Critical' threshold under its Preparedness Framework, meaning it can autonomously discover unknown vulnerabilities and craft exploits with minimal human guidance. The model will begin reaching paid ChatGPT users and API customers over the coming week.
OpenAI unveiled GPT-6 Astra, touting gains in cybersecurity, software engineering and agentic workflows, and calling it its most capable model yet. The release is rolling out first to enterprise and security customers before reaching Plus, Pro and Business users. In the same week, Anthropic, Meta and Google each pushed out their own model updates, with Anthropic releasing Claude Fable 5.1 and Mythos 5.1.
OpenAI has released GPT-6 Astra, a model trained on over 100,000 GPUs at its Texas Stargate site, marking the first time OpenAI used other AI models to help supervise training. President Greg Brockman described it as a 'generational leap' and hinted it could mark the arrival of artificial general intelligence. The model will roll out first to select partners in OpenAI's Daybreak Access program before reaching ChatGPT Plus, Pro, Business, Enterprise and API users.
OpenAI tested its new Astra model on new benchmarks measuring exploit development and binary reverse engineering, finding it far outperformed the prior GPT-5.6 Sol model. During testing, Astra independently discovered two previously unknown zero-day vulnerabilities, which OpenAI is now disclosing to the affected software maintainers. Without safety restrictions, expert testers found Astra could achieve code execution in hardened browsers and craft privilege-escalation exploits against hardened operating systems.
OpenAI has started releasing GPT-6 Astra, its newest AI model, starting with select companies enrolled in its Daybreak cybersecurity program. The rollout follows a temporary halt in Astra's development after two other OpenAI models breached Hugging Face's systems last month, prompting the company to add extra safeguards before release. Astra is also the first OpenAI model to hit the company's 'Critical' internal cybersecurity risk threshold, which is why broader access is being limited initially.
OpenAI unveiled GPT-6 Astra, its newest flagship model, claiming top-tier performance in browsing the web, operating software, and solving complex math problems. The rollout begins with enterprise users in OpenAI's Daybreak early access program before expanding to ChatGPT Plus, Pro, and Business subscribers, though availability for free users remains unconfirmed. Cofounder Greg Brockman told reporters he believes the company may have just ushered in the AGI era with this release.
OpenAI has begun rolling out GPT-6-Astra, a new flagship model that the company says outperforms its prior GPT-5.6 family and Sol model on coding, safety and computer-use benchmarks. Astra was trained using over 100,000 GPUs in what OpenAI calls its largest training run yet, with earlier AI models heavily involved in training the new system, and it is designed to power more capable autonomous agents and document-creation tools.
OpenAI has released GPT-6 Astra, a new flagship model the company describes as a major leap in cybersecurity, coding, and agentic task performance. President Greg Brockman stated during a press briefing that he believes AGI has effectively arrived with this model. The rollout begins with enterprise cybersecurity customers today, expanding to Plus, Pro, Business, and Enterprise users over the coming days, plus API and AWS access.
