OpenAI's newest model can use your computer to finish a task for you.
It came out on September 3. Today I'll show you what it is, what it can do, how to turn it on, and three real examples of people using it.
GPT-6 Astra is OpenAI's newest and most capable model. It was released on September 3, 2026.
The big new thing is computer use. Astra can look at your screen, move the mouse, type, and click through apps and websites to finish a task. You tell it what you want done, and it does it.
It uses your apps the way you would, through the screen. That includes tools that don't connect to AI at all.
It can move between apps and keep going until the whole task is done.
Longer tasks can keep running without you watching every click.
OpenAI says it's about twice as fast at computer use as its last model.
Astra is included in ChatGPT Plus, Pro, Business, and Enterprise. It uses your existing plan, so there's no extra charge.
These come from people who tested Astra and wrote up what happened.
A reviewer on the How I AI show asked Astra to update their lead system, so every new lead would go to the right business partner and get a custom email. Astra took over their Chrome browser and built the whole thing. Doing it by hand had taken them about an hour.
The same reviewer had Astra make a thumbnail. It created the images in one design tool, then opened Figma and put together the finished thumbnail, all while their designer was out.
OpenAI reports that Astra finished Financial Modeling World Cup challenges about four times faster than the winning human competitor. This is OpenAI's own result, not an independent test.

I had a PDF, and I wanted people to see part of it, then give their email to open the rest.
I gave Codex my gated-guide tutorial and asked it to follow it. These are the two prompts from the tutorial that did the work:
There's a document in this folder. Read it and turn it into a single web page that reads like a real guide, not a file dumped on a screen. Keep my headings and lists, make it look right on a phone, and give it a clear title at the top. Use my words — don't rewrite my content, add sections, or invent anything that isn't in the document. Tell me when it's ready and how to look at it.
Cut my guide off after the first section and put an email box there, with one line telling people to enter their email to read the rest. When someone submits it, the rest of the guide opens on the same page.
Send the address to Systeme.io as a new contact. Read my API key from an environment variable called SYSTEME_API_KEY — don't ask me for the key and don't put it in any file.
The most important part: the second half of the guide must NOT be in the page until after someone submits their email. If the whole thing is sent to the browser and just hidden, anyone can read it by viewing the page source and the gate is fake. Fetch the rest from the server only after the email goes through.
Handle someone entering a nonsense email, and don't let a Systeme.io problem stop them reading the guide — I'd rather lose the contact than block a real person.
Before and after. Here's the PDF I gave Codex, and the webpage it built from it.
