Anthropic has enhanced its Claude chatbot by integrating web search capabilities, utilizing Brave Search to provide real-time results and maintain user privacy. This feature, currently in preview for U.S. users of the Claude 3.7 Sonnet model, automatically decides when to consult the web based on the user's query, aiming to deliver the most relevant and up-to-date information with citations included. In addition to web search, Anthropic has introduced a 'think' tool for Claude, which significantly improves the chatbot's complex reasoning capabilities by up to 54% on benchmarks like τ-Bench's airline domain. This tool allows Claude to pause and strategize during multi-step tasks, enhancing its performance in areas such as customer service and tool chain management. The integration of web search and the 'think' tool positions Claude as a strong competitor to other AI chatbots like ChatGPT and Google's Gemini, with plans to extend these features to free users and more countries in the future.
