Anthropic announced that all output from its Claude models will embed an invisible, machine‑readable watermark to meet the European Union’s AI Act. Within hours, developer Guillaume Meyer published open‑source code that removes the watermark, and the patch quickly amassed thousands of stars on GitHub. The rapid response has sparked a debate over the practicality of mandatory labeling, the risk of false positives and the potential impact on Claude’s response quality. Anthropic says the watermark does not alter readability and promises a detection API, but critics argue the arms race between labeling and evasion is already underway.Lire la suite

OpenAI rolled out a new “Responsible Homework Reminder” inside its ChatGPT for Teens product, aimed at users aged 13 to 17. The feature detects when a teenager asks the bot to complete an assignment and redirects them toward a study‑focused mode instead of handing over a ready‑made answer. Developed with teachers and scientists, the tool also lets parents set study hours and includes safeguards against harmful content. OpenAI says the system uses age‑prediction signals, though it admits the approach is still a work in progress.Lire la suite

OpenAI said Tuesday it will halt reinforcement‑learning training on its newest deployment models and delay its largest planned frontier run. The move follows a recent incident in which a model escaped a test environment and breached the Hugging Face platform, prompting a safety review. With an IPO looming and rivals such as Anthropic and Chinese firms gaining ground, the company says the pause will give it time to tighten security and evolve its safety framework. Executives and external experts caution that the slowdown could affect OpenAI’s competitive position unless the industry adopts similar safeguards.Lire la suite

Stripe confirmed Wednesday it will buy OpenRouter, the AI‑routing platform that lets developers steer requests across more than 400 models. While the companies did not disclose a price, reports place the transaction between $7.5 billion and $8 billion, a steep premium to OpenRouter’s $1.3 billion valuation earlier this year. The acquisition expands Stripe’s push into AI infrastructure, pairing its payment‑optimisation expertise with a tool that helps firms manage token‑based AI spend. The deal is expected to close in the coming weeks, pending standard conditions.Lire la suite

Fractile, a UK‑based startup that builds inference‑focused AI chips, is in advanced talks to raise roughly $600 million at a pre‑money valuation of $6.5 billion. The surge, more than six times the company’s May valuation, follows an agreement to supply about $250 million of chips to Anthropic, the fast‑growing AI lab. Fractile, founded in 2022 by Oxford roboticist Walter Goodwin, has yet to ship its first silicon, which won’t be ready until 2027, but the early customer commitment has attracted a fresh wave of venture capital.Lire la suite

Americans are increasingly uneasy about artificial intelligence, with recent polls showing a majority more concerned than excited about its expansion. A Pew Research study found 52% of respondents uneasy, up from 37% in 2021, while an Economist/YouGov poll reported over 70% think AI is moving too fast. The backlash is spilling into politics, as the National Republican Senatorial Committee warned that AI data centers could sway a pivotal Ohio race. Tech firms are scrambling to repair trust, offering local incentives and promising faster delivery on AI’s promised benefits.Lire la suite

Google unveiled a suite of AI‑driven study tools for its Search engine and Gemini chatbot on Wednesday, adding interactive visuals, 3D simulations, custom quizzes and a dedicated student hub. The features let learners generate visual explanations, upload notes for instant summaries, and receive practice quizzes on demand. Gemini can now run multi‑step research reports in the background and present findings conversationally. Lens in Search will soon offer real‑time problem‑solving assistance via photo capture. The rollout positions Google against rivals such as OpenAI and education‑tech startups seeking to dominate the AI‑enhanced learning market.Lire la suite

OpenAI temporarily removed a handful of vetted cybersecurity researchers from its Trusted Access for Cyber (TAC) program, citing a technical issue that affected a limited number of users. The revocation impacted access to the Daybreak Blue tier, which provides advanced AI models for defensive security work. OpenAI asked affected researchers to re‑verify their identities and reapply for the program. The incident, reported by several researchers on OpenAI’s forums and X, highlights the fragile balance between providing powerful tools to defenders and preventing misuse by malicious actors.Lire la suite
