What changed
OpenAI has released GPT-6 Astra, which it describes as its most capable model yet. Company president Greg Brockman says it begins an “AGI era”—a term for AI designed to handle many kinds of tasks—and OpenAI says Astra leads in math, coding, and cybersecurity tests. During testing, it reportedly found two previously unknown security flaws and received the company’s highest safety rating.
What this means for you
Astra may offer stronger performance for coding, mathematics, and cybersecurity, but the supplied information does not say who can access it, how much it costs, or whether it is broadly available. Its ability to find unknown security flaws also highlights the need for careful safeguards when using advanced AI.
