Anthropic has announced the release of Claude 2, its latest AI model. The upgraded version brings substantial improvements in performance and expands the model's ability to generate longer responses. Designed to function as a personal assistant, Claude 2 now has enhanced capabilities in areas such as coding, mathematics, and reasoning.
