On Wednesday, September 23, two major artificial intelligence companies, Anthropic and OpenAI, introduced new AI models. These models are designed to perform complex tasks such as answering questions, generating text, and even coding. The same day, Chinese regulators began an investigation into two domestic AI firms, Deepseek and Moonshot AI, possibly related to data privacy or market competition concerns. In other tech news, Apple is currently testing a health bracelet that does not include a traditional screen. This device is expected to monitor health metrics such as heart rate and activity levels, offering users a more discreet way to track their well-being. Meanwhile, the French defense company Dassault is experimenting with two AI algorithms on the Rafale fighter jet, aiming to enhance its capabilities in areas like target recognition and decision-making during missions. In a notable return, Lycos.fr, a once-popular French internet service provider and website, has re-launched after a long absence. This revival may signal a renewed interest in classic web services or a shift in digital strategies by the company. This information was covered in Le Tech Flash, a segment hosted by Léa Benaim. The segment is available to view or listen to from Monday to Thursday as part of Tech&Co, the daily show hosted by François Sorel on BFM Business.
