Claude Sonnet 4.6 promises to handle paperwork for you. Now it has the challenge of its life: dealing with Spanish administration websites

Anthropic's Claude Sonnet 4.6 represents a significant advancement in AI capabilities, shifting from pure reasoning to active task execution. This new iteration can navigate websites, complete forms, and interact with digital interfaces using mouse and keyboard inputs, mirroring human actions. This evolution positions AI as a practical agent capable of handling complex digital processes, a notable departure from its prior role as a passive information provider. The enhanced functionality of Sonnet 4.6 is demonstrated through its ability to perform tasks like renewing vehicle registrations on government websites, a process that often involves intricate online forms and navigation. While the initial demonstration focused on a seemingly user-friendly system, the real test lies in its capacity to manage the complexities of more challenging digital environments, such as official administrative portals. This capability signals a new frontier in AI's practical application for users. Following closely behind the release of its most powerful model, Opus 4.6, the Sonnet 4.6 upgrade offers a substantial leap in performance for a broader user base, including those on free plans. Anthropic reports significant improvements in OSWorld benchmarks, indicating sustained development in AI's computer usage proficiency. This advancement means that tasks previously requiring more advanced AI models can now be handled by Sonnet 4.6 at its existing price point, optimizing accessibility and efficiency.
