Anthropic is poised to introduce new features to its Claude AI model, including a 'Thinking Model/Mode' and web search capabilities, as suggested by recent updates to the Claude iOS app. Symbols such as 'Steps', 'Think', 'MagnifyingGlass', and 'Quotes' have been identified in the app, hinting at these upcoming functionalities. The web search feature is currently in a beta toggle state, indicating it may require a new model release to become fully operational. These developments, which include 'reasoning model', 'researching deeper', and 'browsing on the web' capabilities, are expected to be part of the imminent release of Claude 4, according to various sources.
