A new study published in PNAS Nexus reveals that leading large‑language models, including GPT‑4o and Claude 3.5 Sonnet, perform poorly on the Stroop effect test, especially as task length increases. While humans maintain roughly 95% accuracy even in extended trials, the AI systems’ accuracy drops sharply, highlighting a fundamental gap in executive attention that researchers say must be addressed before artificial general intelligence can be realized.

Meta has yet to release an API for its Muse Spark large‑language model, despite promising developers the tool would be available in June. The Wall Street Journal reported that the company announced the model in April but provided no firm launch date for the API, leaving developers who want to integrate the closed‑source AI into their applications in limbo. A Meta spokesperson reiterated the June target, but weeks have passed without a public rollout. The delay adds pressure on the social‑media giant as rivals such as Microsoft, Google and Apple push their own AI services forward. Read more

Cloudflare CEO Matthew Prince announced Wednesday that AI‑driven agents now generate more internet traffic than human users worldwide. Data from the company's Radar service shows agentic bot activity accounting for 57.4% of total web requests, while human‑originated traffic fell to 42.6%. Prince said the shift happened faster than he expected, noting that the trend is already evident across most regions, with North America seeing the highest bot share. The rise reflects the growing use of AI chatbots that browse the web on users' behalf. Read more

Anthropic, the AI model developer that recently raised $65 billion at a $965 billion valuation, has confidentially filed for an initial public offering. Co‑founder Daniela Amodei told Bloomberg Tech that the move is driven by the massive capital needed to train and run large models. The company reported annualized revenue of more than $47 billion in May, a sharp jump from roughly $9 billion at the end of 2025, underscoring rapid growth even as some firms reassess AI spending.

Mira Murati, former OpenAI CTO and now chief executive of Thinking Machines Lab, gave her first extensive media interview in 18 months. Speaking with Bloomberg in San Francisco, she previewed the startup’s new “interaction models,” AI systems that process continuous streams of audio, text and video in near‑real time. Murati also reflected on her brief stint as interim OpenAI CEO during the 2023 board upheaval and warned that the industry’s decision‑making is too concentrated. The interview signals Thinking Machines’ push to re‑enter the public AI arena while underscoring governance concerns. Read more

Airbnb chief executive Brian Chesky is set to back a new artificial‑intelligence laboratory, a move that signals the hospitality platform’s deeper push into AI research. While Airbnb has already integrated AI‑driven coding tools, Chesky said the company has not yet formed a partnership with any large‑language‑model provider because existing products do not meet its standards. The new lab, whose focus is expected to center on user interaction and design, will operate under Chesky’s oversight but will not be led by him personally. A company spokesperson declined to comment further. Read more
