ChatGPT Atlas

ChatGPT Atlas is an AI-powered web browser developed by OpenAI in 2025, designed to merge intelligent conversational computing with traditional web navigation. The platform integrates ChatGPT’s GPT‑4o and GPT‑5 models directly into the browser interface, transforming search and browsing into an interactive, reasoning-driven experience. Atlas was launched as an AI-first browser positioned to compete with Google Chrome and Perplexity Comet while extending OpenAI’s ecosystem beyond chat-based applications.

​

• Built around OpenAI’s large language models with real-time reasoning and automation capabilities.
• Designed to make browsing conversational, contextual, and memory-enabled.
• Available globally for macOS users, with upcoming support for Windows, iOS, and Android.

OpenAI, founded in 2015 by Sam Altman, Elon Musk, Greg Brockman, Ilya Sutskever, and Wojciech Zaremba, developed ChatGPT Atlas as part of its 2025 product expansion strategy. The company has evolved from a non-profit AI research lab into a $300 billion enterprise leading in applied AI. Atlas marks OpenAI’s entrance into the AI-native browsing market, bridging ChatGPT’s massive user base into a full product ecosystem.

OpenAI expanded its application and developer ecosystem through several key acquisitions preceding and supporting Atlas’s launch, reinforcing its expertise in code intelligence and AI infrastructure.

​

• Acquisition of Windsurf (formerly Codeium) – $3 billion deal to enhance AI-assisted coding across developer environments.
• Acquisition of Statsig – $1.1 billion all-stock deal to strengthen product testing and experimentation frameworks.
• Product Expansion: Integration of Atlas into ChatGPT’s Plus, Pro, and Business tiers, extending AI browsing to enterprise and developer markets.

Atlas introduces several innovations that differentiate it from standard browsers, positioning it as the first truly agentic browsing platform.

​
