OpenAI Launches ChatGPT Atlas Browser, Taking Direct Aim at Google Chrome

/in /tarafından

OpenAI unveiled ChatGPT Atlas on Tuesday, its first AI-powered web browser, positioning it as a serious challenger to Google Chrome’s dominance. Built around the company’s flagship chatbot, Atlas integrates conversational search, task automation, and real-time web interaction into one platform — a move that could reshape how users navigate the internet.

With more than 800 million weekly ChatGPT users, OpenAI aims to extend its reach into everyday browsing, potentially capturing vast amounts of consumer interaction data and accelerating the shift from keyword searches to AI-driven query synthesis. The launch triggered market ripples, with Alphabet (GOOGL.O) shares falling 1.8% in afternoon trading.

Atlas introduces features such as a ChatGPT sidebar that summarizes articles, compares products, and extracts data directly from websites. A premium “agent mode” allows ChatGPT to autonomously complete online tasks, from trip planning to shopping. In a live demo, the AI browsed for a recipe, then purchased all listed ingredients via Instacart, demonstrating what OpenAI calls “autonomous digital agency.”

The browser debuted on Apple’s macOS, with Windows, iOS, and Android versions coming soon. OpenAI CEO Sam Altman said the launch represents the company’s broader mission to “reimagine how people interact with information and the web.”

The move intensifies OpenAI’s rivalry with Google, which has been embedding its Gemini AI model into Chrome and search results. Google Chrome still commands 71.9% of the global browser market, according to StatCounter, but analysts say Atlas could erode that lead — especially if OpenAI enters the digital advertising space.

“Integrating chat into a browser is a precursor for OpenAI to start selling ads,” said Gil Luria, analyst at D.A. Davidson. “If it does, it could take a meaningful share of search advertising from Google, which currently holds about 90% of that market.”

The launch of Atlas marks a new phase in OpenAI’s challenge to Big Tech dominance, potentially transforming how people browse, search, and transact online — and redefining the balance of power in the AI era.

Experts divided over whether AI boom is a bubble or sustainable revolution

The massive wave of investment in artificial intelligence has triggered debate across global markets over whether the surge mirrors the dot-com bubble or represents a sustainable technological revolution. Companies have poured hundreds of billions of dollars into AI infrastructure, fueling record valuations — but also investor caution.

A BofA Global Research survey showed that 54% of fund managers now believe AI stocks are in a bubble, compared with 38% who disagree, highlighting the growing divide between optimism and skepticism.

The Bank of England warned on October 8 that global markets could tumble if sentiment toward AI shifts, saying “the risk of a sharp market correction has increased.”

Other experts, however, see the AI boom as a long-term growth story. Goldman Sachs economist Joseph Briggs argued that the investment surge remains macroeconomically sustainable, though he noted that “the ultimate AI winners remain less clear.”

ABB CEO Morten Wierod echoed that sentiment, saying, “I don’t think there is a bubble, but we do see constraints in construction capacity,” adding that the industry is dealing with “trillions in investment” and limited human resources.

Amazon founder Jeff Bezos said investor enthusiasm is not inherently negative: “When people get very excited … every experiment gets funded. Some will fail, but society benefits when the winners emerge.”

IMF chief economist Pierre-Olivier Gourinchas compared the AI boom to the early 2000s tech frenzy but said it’s less likely to trigger a systemic crash because it’s not driven by debt.

OpenAI CEO Sam Altman offered a more candid view: “Are investors overexcited about AI? Yes. Someone is going to lose a phenomenal amount of money — and others will make a phenomenal amount.”

Despite these warnings, UBS strategists found that 90% of investors who believe in an AI bubble remain heavily invested, suggesting confidence in the sector’s long-term potential even as valuations soar.

OpenAI to permit mature content on ChatGPT for verified adults from December

/in /tarafından

OpenAI will begin allowing mature content on ChatGPT starting in December for users who verify their age, CEO Sam Altman announced on Tuesday. The decision marks a major policy shift under OpenAI’s new “treat adult users like adults” principle, following earlier restrictions that limited the chatbot’s ability to handle sensitive topics.

Altman said on X (formerly Twitter) that the company made ChatGPT “pretty restrictive” to avoid harm to users experiencing mental distress, which he acknowledged had made the chatbot “less useful or enjoyable” for others. “As we roll out age-gating more fully … we will allow even more, like erotica for verified adults,” he said.

The move comes as OpenAI develops new safety tools and moderation systems aimed at identifying mental health risks and ensuring appropriate usage. Altman added that the company now feels confident it can safely relax restrictions for most adult users while maintaining strong protections for minors.

In parallel, OpenAI plans to roll out a customization feature that lets users adjust ChatGPT’s tone and personality, including more expressive or conversational styles. “If you want ChatGPT to act more human-like or friendly, it should — but only if you want it,” Altman said.

The announcement came the same day Meta introduced new PG-13-style content filters on Instagram, underscoring the growing trend among tech firms to tailor content standards by user age and consent verification.
