I tested both the web version and the client version. The model selected is 4o, and I manually enabled network search. However, the returned results cannot access the internet. When asking the model in network search mode, it responds that this feature is currently not available.
Further test results… It was found that if you call o3-mimi, the web search function can be used normally. The current issue is that after enabling the web search function on the Mac OS client, the dialog box cannot input Chinese characters… Wow, this problem did not occur in versions before January 15th. Your front-end programmers are really lacking!
