Anthropic. Reuters The American artificial intelligence (AI) company Anthropic obtained the highest score in a biannual security ranking, but on a global level the sector is unable to combat "existential" threats, according to a report published this Tuesday (7). The Future of Life Institute, an American AI safety think tank, evaluated nine of the world's leading AI companies and defined a ranking based on public data and information provided by the companies themselves. The nine companies are failing to combat "existential" threats, such as developing models that achieve a human-like level of intelligence, known as "artificial general intelligence" or AGI, the report adds. Efforts were analyzed in six categories: risk assessment; current damage; security structures; existential security; governance and transparency, and; information sharing. Pope warns about artificial intelligence No company received an "A", the highest grade, in any category, while Anthropic obtained the best overall grade, a "C+". The report highlights that several companies that previously prohibited the military use of their technology have been "gradually reversing course", including Anthropic, which was criticized for maintaining "questionable military commitments". The U.S. government has used Anthropic's technology in military operations in Venezuela and Iran over the past year, according to multiple press reports, although the company was recently the subject of a Pentagon ban over disagreements over AI safety. Although "there are constructive attempts", the efforts as a whole are "totally insufficient". Other risks include the possible misuse of a model to carry out a cyberattack or perform tasks that are potentially harmful to humans.
