ChatGPT Atlas October 2025 Update: More Stable Agent Mode and Fully Working 1Password Support

OpenAI rolled out a major update for ChatGPT Atlas on October 28, 2025, aiming for something simple: remove annoying bugs, make everyday browsing easier, and keep automation features running smoothly. And sure enough—after installing the 1.2025.295.4 build, two changes are instantly noticeable: 1Password finally works properly, and Agent Mode no longer freezes or crashes when paused or resumed.

I’ve been using Atlas as my main browser on macOS for a while, and these two fixes alone make it feel way more reliable.

1Password Finally Works Like It Should

Before this update, 1Password integration was frustrating. Autofill didn’t show up, the extension button ignored clicks, and pop-ups wouldn’t open on new tabs.

• 1Password connects to the native app correctly
• Works even without the native 1Password app installed
• Extension pop-ups open normally, including on the New Tab page
• Autofill shows up instantly when logging into sites

Real experience: I use 1Password for everything—work accounts, banking, shopping. Before, I had to switch back to Chrome whenever Atlas refused to autofill. Now, logins work smoothly. It finally feels like a modern browser again.

Agent Mode Is More Reliable

Agent Mode is what makes Atlas different from Safari or Chrome. It doesn’t just summarize pages—it can perform multi-step tasks for you.

In older versions, Agent Mode sometimes got stuck midway or slowed the browser down after pausing.

• Agent uses a separate clipboard (safer and cleaner)
• Pause/Resume no longer slows down the browser
• Multi-step workflows run more smoothly

Real test: I asked Agent to find a recipe, build a shopping list, and add items to a grocery cart. In the previous version, it sometimes stopped halfway. After the update, it handled the whole flow without lag. If I paused it, resuming didn’t break anything. That’s a big improvement.

Smaller Fixes You’ll Notice Daily

• Atlas warns you before quitting with Cmd+Q
• Switching windows with Cmd+Shift+` now works properly
• Unpinning tabs no longer causes visual glitches
• The Ask ChatGPT sidebar works even on sites without favicons
• No more random “0 words” hover text

Security and Privacy Still Matter

• Agent can’t run code in the browser
• Can’t access your saved passwords or autofill data
• Can’t view your file system
• Pages visited by Agent aren’t added to your history

You stay in control. Pause it, stop it, or take over anytime.

Is This Update Worth It?

If you tried Atlas before and gave up because 1Password was broken or Agent Mode felt unreliable—yes, this update is worth coming back.

After updating:

• I no longer need Chrome just to log in
• Agent Mode finally feels like a real assistant

Atlas is slowly becoming a true productivity browser—not just a browser with ChatGPT tacked on top.
