The US government has lifted export controls on Anthropic's most advanced artificial intelligence (AI) tools, just weeks after ordering it to restrict access to them over national security concerns, the company has said. Anthropic said in a social media post that it will begin restoring access to Claude Fable 5 and Mythos 5 on Wednesday after being notified that the US Department of Commerce has lifted export controls on the two models. They are the firm's most advanced AI tools, which were abruptly suspended on 12 June over concerns that they could be used by hackers to exploit weaknesses in computer systems. The BBC has contacted the Department of Commerce for comment. Mythos and Fable are two of Anthropic's AI models built on its Claude platform - a rival to the likes of OpenAI's ChatGPT and Google's Gemini. Fable 5 is a version of the AI model for the cosumer market, capable of deep reasoning and can perform complex tasks independently.

IBM hails new'block of flats' design breakthrough for ultra tiny chips Image caption, IBM's new sub-1 nm chip crams almost 100 billion transistors onto a surface the size of a fingernail IBM has unveiled a new chip design which it says could enable manufacturers to cram 100 billion transistors on a silicon chip the size of a fingernail. The current industry-standard size for chips, measured in a the unit of nanometres - a billionth of a metre and the size of a few atoms - is around two nanometres (nm). But IBM claims its new chip tech is the equivalent of around 0.7nm, which may make it the world's first known chip technology below 1nm. However, it will be several years before the chip tech could be ready to go into production. The firm claims in tests, its prototype performed 50% better than its own 2nm chip and was 70% more energy efficient.

US artificial intelligence (AI) giant Anthropic has accused Chinese e-commerce and technology firm Alibaba of brazenly and illicitly extracting its Claude AI model's capabilities. In a letter sent to two members of the US Congress, the San Francisco-based company said operators linked to Alibaba carried out almost 29 million exchanges with Claude using thousands of fraudulent accounts in what it called the largest extraction campaign of its kind. Anthropic urged Congress to penalise the companies behind attacks like this and to ramp up measures to prevent US tech from being stolen. The BBC has contacted Alibaba for comment and requested more details from Anthropic. Anthropic's letter, dated 10 June and addressed to US Senators Tim Scott and Elizabeth Warren, accused New York Stock Exchange-listed Alibaba of carrying out the largest campaign to illicitly extract Claude's capabilities.
