OpenAI has already abandoned its controversial ChatGPT Atlas browser

AI browsers have been popping up more and more over the past year, and ChatGPT Atlas was just one of a handful that started making waves in 2025. Launched in October for macOS, the browser brought ChatGPT to the forefront when browsing the internet. However, after less than a year of operation, OpenAI is already abandoning its Atlas browser. The announcement is part of a series of tweets on X detailing the big changes coming to ChatGPT with the release of GPT 5.6.

In the articles, OpenAI’s James Sun notes how the browser team worked to create some improvements directly in the ChatGPT desktop app, as well as in the browser’s new Work mode. In the announcement’s final tweet, Sun noted that the team is discontinuing Atlas and that all the things the team learned from Atlas have been incorporated into the changes that will debut with version 5.6, including a new cloud browser for AI agents, as well as updates to the ChatGPT extension that will bring some of Atlas’ best features to any browser that supports the extension (via Android Authority).

The death of ChatGPT Atlas is certainly surprising, although it is far from the first of its babies that OpenAI has killed in the past year. Earlier this year, the company discontinued its Sora AI video app after only a few months of availability. In Atlas’ case, however, the browser never really made the leap beyond macOS, meaning iOS, Windows, and Android users were never able to take advantage of it. This already puts the browser behind other AI-based options like Comet and Chrome.

However, Atlas’ functionality will live on, in a way, with new features built directly into the ChatGPT app and its browser extension. The app will feature a full-featured built-in browser with support for password managers + autofill, full passkey support, downloads, printing, multiple tabs, and a host of other features important to web browsing. Additionally, ChatGPT and Codex will be available directly in Google Chrome with Side Chat. You will need to install the ChatGPT extension to take full advantage of Side Chat and the features it offers. The company also notes that support for other browsers will be available soon.

Atlas isn’t dead in the water yet either. Sun says OpenAI is aiming to deprecate the app by August 9, 2026, so you still have time to continue using what Atlas offers if you’ve fallen in love with it. Of course, there are tons of other AI browsers, including Perplexity’s Comet, and Google Chrome and Microsoft Edge now have AI features built in directly.

For the most part, it seems that many ChatGPT and Atlas fans are unhappy with the decision to kill the browser, with one When asked about the decision, Sun noted that the team decided to discontinue Atlas because it found that asking users to switch browsers was much more difficult than simply building the features they needed to work directly in the browser they were already using.

Additionally, Sun says the company realized that developing an entirely new browser didn’t play to its strengths, namely its models and AI agents it already has. It also didn’t fit with their mission to make AI useful to everyone. As such, the company decided to change course, focusing its attention on bringing the best features of Atlas to the browser its users already use.

However, Sun also mentioned that there would never be a 1:1 recreation of Atlas in the ChatGPT app. Instead, the team will focus on the features their agents need to improve user workflows and continue iterating from there. ChatGPT already supports multiple apps, so seeing it get more widespread support across browsers could also be a big win for users, especially now that Atlas is on its way out.
