# OpenAI Releases GPT-6 Astra with Cybersecurity Capabilities

> OpenAI has begun a controlled rollout of GPT-6 Astra, which it describes as the first model to reach its critical cybersecurity capability threshold. In testing, Astra posted a perfect score on ExploitBench and, more notably, discovered and exploited two previously unknown zero-day vulnerabilities on its own. That cuts both ways, so the release comes wrapped in safeguards and a new $1B initiative called Daybreak, aimed at helping frontline defenders protect critical infrastructure. Access is rolling out gradually to ChatGPT Plus, Pro and Business tiers and to API partners. This is the moment security researchers have warned about, a general model genuinely good at finding and weaponizing software flaws. It could give defenders a powerful new tool for hardening systems, but the same capability in the wrong hands is exactly why OpenAI is gating access and funding the defensive side so heavily.
