OpenAI has begun rolling out GPT-6 Astra, a model it says reaches 99.9 percent on ARC-AGI-3, a benchmark for artificial general intelligence (AGI), and human-level action efficiency on 96 percent of that benchmark's levels. Astra is the first OpenAI model classified at the Critical cybersecurity threshold, meaning that with tools and access it can discover unknown flaws and develop exploits across hardened systems without step-by-step human direction. OpenAI delayed parts of the release to strengthen containment and is initially limiting access. It does not call Astra AGI.

OpenAI's charter defines AGI as a highly autonomous system that outperforms humans at most economically valuable work. One saturated benchmark cannot prove that claim, and Astra still falls below the company's High threshold for AI self-improvement. Yet a turning point can arrive before its official name. Astra combines reasoning with direct computer use across long professional workflows. That changes the unit of automation from an answer to a finished assignment. Scientists may compress weeks of technical work. Offices may remove layers of junior labor. Cyber defenders and attackers may search for the same unseen vulnerability at machine speed. The human consequence depends on who can delegate, who owns the infrastructure, who is displaced and who retains authority to stop the task. If Astra is remembered as an AGI milestone, the evidence will come from workplaces, laboratories, public agencies and security incidents rather than the launch page.
