GPT-6 Astra: OpenAI's "Most Intelligent" Model Arrives

OpenAI is releasing a major upgrade to ChatGPT and Codex with GPT-6 Astra. The company calls this its "most intelligent and aligned model." GPT-6 Astra shows state-of-the-art performance in areas like computer use, software engineering, and science. It scores 98% on FrontierMath Tier 4 and 99.9% on ARC-AGI-3. Astra also achieves a 100% score on ExploitBench. What's interesting is Astra improves computer use, letting ChatGPT utilize your Mac or other desktop, even in the background. It combines intelligence for complex problems with the ability to create polished documents and presentations. For Codex, Astra introduces a new way to preserve context. It can keep notes across context windows, saving accumulated details without repeated compression. This means earlier context windows remain searchable. This experimental feature is rolling out now and will become the default for Astra in the coming weeks. OpenAI also notes GPT-6 Astra is a "significant jump in cyber capabilities," meeting the Critical threshold in cybersecurity. Astra is rolling out today to a limited set of organizations and will become available to all ChatGPT Plus, Pro, Business, and Enterprise users in the coming days. The bottom line is this upgrade promises enhanced capabilities for professional and technical tasks.
