GPT 5.1 shipped on November 12, 2025, and it’s now rolling out to Copilot on Windows, including for those who use Microsoft’s AI without a paid subscription. That makes sense as GPT 5.1 is also free on ChatGPT, but Copilot gives you access to GPT 5.1’s Thinking models without a subscription.
Microsoft told me that GPT 5.1 is being rolled out on Copilot gradually, and it won’t show up right away. You don’t have to log out, create a new account or update the Copilot app on Windows or anywhere else to see the new GPT 5.1. It’s a server-side rollout, and I’m only seeing it in the Copilot app. I don’t have it on the web.
I’m also subscribed to Microsoft 365, but I don’t think that helps with the access, as it only reduces the usage limitations.
GPT 5.1 is the default “smart” mode in Copilot, but if you switch to Think Deeper, Copilot will use GPT 5.1 in ‘Thinking mode.’
Now, this is only available on ChatGPT if you pay at least $20…
