GPU cloud grew 283% year-over-year, marking four consecutive quarters of triple-digit growth. 13F filings show Duquesne Family Office under Druckenmiller initiated a position in Baidu ADRs in Q2, and another Wall Street fund is also increasing its stake.

💻 II. AI Software

In DepthDoubao task upgrade: Virtual desktop directly operates Windows computers

Doubao's virtual desktop is based on more general GUI capabilities. Without MCP, APIs, plugins, or CLI, it can understand interfaces and complete operations, supporting cross-software tasks without taking over the user's working environment. Skipping APIs to directly "look at the screen and operate" is the most universal agent interaction method, allowing Agents to finally reach all legacy enterprise applications.

🌐 V. Physical AI and World Models

In DepthECB economists warn: AI is brewing a market correction

European and US stocks have hit new highs amid the AI boom, but ECB economists warn that historically, extreme valuation concentration and rapid rises are often followed by corrections. The fragility of the AI narrative is accumulating. When central bank economists openly discuss risks, the market treats this as a signal. The pullback pressure on AI-heavyweight stocks is worth vigilance.
