A team of computer scientists from the University of Tübingen, the Max Planck Institute, MATS Research and security firm Snyk has demonstrated a method to pull hidden "reasoning traces" from flagship AI models such as Claude, GPT and Gemini. The technique, which can also reveal passwords and API keys, prompted OpenAI, Anthropic and Google to patch their APIs. The study found that the Chinese open‑weight model Kimi K3 mirrors the extracted reasoning of Claude and GPT, fueling debate over whether Chinese firms are distilling U.S. models to boost their own capabilities.Read more

Anthropic announced that all content produced by its Claude models released on or after Aug. 2 will carry invisible watermarks. The move aims to meet the European Union’s Code of Practice on Transparency for AI‑generated material, which requires providers to flag AI output for consumers. Watermarks will appear in both text and image files, remaining intact even after copying, pasting or basic editing, and can be detected by machine tools. Anthropic said it will later disclose how to read the markers, while noting that the presence or absence of a watermark does not guarantee the content’s origin.Read more

OpenAI announced Wednesday that Brad Lightcap, the company’s special projects lead and former chief operating officer, will depart after an eight‑year tenure. In a memo posted to X, Lightcap said he is moving on to “something new” and will remain on staff for a few weeks to ensure a smooth transition. His exit follows a series of high‑profile departures and a broader reorganization as the AI lab readies itself for an upcoming public offering.Read more

Google announced that its Gemini AI chatbot has surpassed 1 billion monthly users, making it the 14th Google product to hit that mark and the fastest‑growing service in the company's portfolio. The milestone was shared by CEO Sundar Pichai on X. OpenAI’s ChatGPT hit the same threshold weeks earlier, though the company disclosed the figure only in an August blog post. Both firms cite rapid adoption across Android and iOS platforms, while competitors such as Anthropic and Claude remain far behind in user counts.Read more

SpaceXAI rolled out Grok Bot, a beta AI agent suite that can log into apps and websites, retain task context and collaborate across multiple agents. Initially available to SuperGrok Heavy, Cursor Ultra and Cursor Teams Premium subscribers, the service runs on macOS, Windows, Linux and iOS, with Android slated for later. The launch follows SpaceXAI’s $60 billion acquisition of Cursor’s parent Anysphere and comes amid growing competition from OpenAI and other firms developing office‑focused AI assistants.Read more

Brad Lightcap, OpenAI’s longest‑serving executive, announced his exit from the AI research lab to “start something new.” The former CFO and COO, who joined the company in 2018 and recently led special projects, shared a brief internal note hinting at future plans. His departure follows a series of senior exits as OpenAI readies for a high‑profile IPO.Read more

Anthropic announced that an unreleased large‑language model has pushed the lower bound of cases where the Riemann hypothesis holds, after a staff member with limited mathematical training set the system loose for 36 hours. The model explored 650 approaches with 60 sub‑agents, generating 31 million tokens and producing a draft paper that two in‑house mathematicians verified using the Lean proof assistant. The breakthrough adds to a string of AI‑driven results in pure mathematics and reignites debate over the role of machine‑generated proofs.Read more

Google announced that its Gemini chatbot has surpassed 1 billion monthly active users, making it the company’s 14th product to reach that milestone. CEO Sundar Pichai highlighted rapid growth, new Gemini 3.5 Flash features and soaring voice‑chat usage, while noting the figure excludes other Google AI channels. The news arrives after a strong Q2 earnings report and ahead of the upcoming Made by Google event.Read more

AI startup River AI, founded by former DeepMind and OpenAI researcher Igor Babuschkin, announced a $1.1 billion seed/Series A financing round. The investment, led by General Catalyst and AMP PBC, also includes Nvidia, AMD Ventures, Y Combinator and Temasek. River aims to rebuild the entire AI stack so that individuals and enterprises can train their own personal assistants, shifting the focus from generic task bots to truly private, adaptable agents.Read more

OpenAI announced a preview release of a native ChatGPT desktop application for Linux on Tuesday, expanding the chatbot’s reach to the open‑source operating system. The app, which bundles ChatGPT, ChatGPT Work and Codex, supports Ubuntu 24.04 and 26.04 LTS, Debian 13, and Fedora 43 and 44. OpenAI said the move responds to long‑standing demand from developers and users. The rollout is worldwide and arrives a month after Anthropic launched its own Claude desktop client for Linux.Read more
