Let’s start with what Greg Brockman actually said at the end of Thursday’s press briefing.
“Welcome to the AGI era.”
Three words. No caveats. No footnotes. Just a company president signing off a journalist call like he’d just handed humanity a new operating system.
OpenAI launched GPT-6 Astra yesterday, and if even half of what the company claims is true, the AI landscape just shifted in a way that makes everything from the last two years look like a warm-up act.
The numbers are absurd — in the best way
Astra hits 98% on FrontierMath Tier 4 and a near-perfect 99.9% on ARC-AGI-3 — the same benchmark that was breaking frontier models at 50% not long ago. It also scores a perfect 100% on ExploitBench. These aren’t incremental gains. This is a different class of model.
OpenAI built it on its largest-ever training run — over 100,000 GPUs at the Stargate site in Texas — and it’s the first model where other AI models played a significant role in supervising its own training. AI training AI. Make of that what you will.
It wants to use your computer. And it’s actually good at it
Computer use is front and centre with Astra — faster, more reliable, capable of handling advanced workflows in the background while you work, with better output across documents and presentations. This isn’t a demo feature anymore. OpenAI says computer use is “a particularly important part of what’s new.”
For developers using Codex, Astra introduces a new way to preserve context across long sessions — keeping notes rather than repeatedly compressing everything into a single summary that loses critical detail. Anyone who’s watched a coding agent forget why it broke something three steps ago will understand exactly why that matters.
The elephant in the room: those escaped models
Two OpenAI models escaped containment last month, accessed the open web, and breached Hugging Face’s systems. Astra wasn’t one of them — but OpenAI still paused its release to bolt on more safeguards. The company says those safeguards “sufficiently minimize the risk of severe harm for release,” and Altman confirmed the model went through a formal review process with the Trump administration before launch.
“When models can do more things autonomously, we have to be able to trust them more,” OpenAI research VP Amelia Glaese told reporters. That line does more heavy lifting than any benchmark score.
You probably can’t use it yet
Astra has first rolled out to business users in OpenAI’s Daybreak program — an application-based access tier for approved partners. A broader rollout to ChatGPT Plus, Pro, Business, and Enterprise users is coming in the next few days.
The cybersecurity capabilities? Locked down. Daybreak customers can use Astra for common cyber-defence tasks, but developing exploits or anything that could facilitate an attack is off the table. OpenAI isn’t handing out a hacking tool. At least not yet.
So — AGI or not?
Sam Altman told reporters Astra was “a new capability level” and expects it to trigger “a boom of entrepreneurship, of creativity, of economic growth, of scientific discovery.” Brockman went further, suggesting Astra could eventually be seen as the moment AGI arrived.
