Beating AI Express News: Tencent announces deep integration of WeChat Work and WorkBuddy. In the new WeChat Work 5.0.12, WorkBuddy is officially added to the corporate directory, allowing employees to chat with it, assign tasks, or add it to work groups just like contacting colleagues.

WorkBuddy 5.8.0 supports direct login via WeChat Work accounts. Within the scope of enterprise authorization, it can access 10 office capabilities including chat messages, documents, meetings, and WeChat Drive.

Administrators can assign WorkBuddy accounts, set data access permissions, and use the "Observability Center" (which launched its public beta on October 13) to monitor departmental point consumption, model usage, task duration, and even track issues in specific execution steps.

Boston Federal Reserve President Susan Collins said Tuesday she currently believes the U.S. Federal Reserve may need to raise interest rates further before the end of this year to ensure inflation returns to its 2% target in a timely and sustained manner. However, she emphasized that any further policy tightening and the timing of such actions will depend heavily on upcoming economic data and how these data shape her assessment of the economic outlook and balance of risks. Collins warned that artificial intelligence (AI) infrastructure development could trigger an excessively large investment boom. If related demand further fuels household spending and overheats the labor market, inflation could remain above the Fed's target for an extended period.
