AI summary: US-based AI company, Anthropic, has launched a chatbot, Claude 2, that can summarize large blocks of text and operates based on safety principles from sources like the Universal Declaration of Human Rights. The chatbot, available in the US and UK, is part of the growing debate over AI safety and societal risk. However, it has shown a tendency for factual errors. Meanwhile, the Writers’ Guild of Great Britain has called for an independent AI regulator, amid concerns over AI’s impact on authors’ income and copyright issues.
