Anthropic introduces an upgraded Claude 3.5 Sonnet model and a new Claude 3.5 Haiku model, both demonstrating significant improvements in coding tasks. Additionally, the company announces the public beta of computer use capability, allowing developers to direct Claude to use computers like people do. This feature is currently experimental and may present challenges, but it has potential applications in automation, software development, and research. The upgraded Claude 3.5 Sonnet model is now available for all users, while the new Claude 3.5 Haiku will be released later this month.
