OpenAI will not be defeating Google Chrome or Mozilla Firefox in the web browser market. The AI company announced plans to sunset Atlas, a stand-alone browser it released last fall, and roll its technology into a suite of tools in its desktop app.
OpenAI said earlier this year that it was developing a "superapp" for Macs and Windows, but did not mention at the time that Atlas would be rolled into that.
At the time of its release, Atlas seemed like a natural evolution of OpenAI's takeover of the world, bringing its popular chatbot ChatGPT to web browsers with the potential to turn web searches into conversational prompts. But OpenAI had stiff competition from other AI-enabled browsers, including Perplexity's Comet, Microsoft's Edge with Copilot and Brave, among others.
In its race to keep up with its biggest competitor, Anthropic, OpenAI appears to be narrowing its focus to advancing its core AI technology rather than pursuing what the company calls "side quests." OpenAI just released its latest version of ChatGPT, 5.6.
(Disclosure: Ziff Davis, CNET's parent company, in 2025 filed a lawsuit against OpenAI, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.)
The Atlas sunset date is set #
In a post on X, OpenAI developer James Sun said Atlas is expected to go away as a stand-alone product on Aug. 9. He wrote that its abilities will be part of the new features in the desktop app and other products.
"All these capabilities were built on what we learned from Atlas users who took a leap of faith on a new browser," Sun said. "You taught us how agents can help make browsing and doing work on the open web better, and we are applying these learnings to these new products."
Lastly, with all these updates, we are going to be sunsetting Atlas.
