Shing-Tung Yau's Paper Acknowledges GPT and Claude

According to the title information from src-1, mathematician Shing-Tung Yau acknowledges GPT and Claude in a new paper, and the relevant text mentions that the problem was "personally included on a problem list 44 years ago." This clue points to AI tools having entered the front-line workflow of fundamental research such as mathematics. ^[1]

Nvidia Shares Hit a Record High, Market Cap Nears $6 Trillion

Nvidia's share price hit an all-time high for the first time since May, as investors piled back into the stock after a two-month selloff wiped more than $1 trillion off its market value. Shares of the world's most valuable listed company rose 2.9% on Friday, rebounding nearly 25% from a late-July low. Nvidia's stock is up about 27% year to date and is on track for a fourth consecutive year of double-digit gains. The company's market cap is currently about $5.7 trillion, less than $300 billion away from becoming the first company in history to reach a $6 trillion market cap. ^[2]

Tencent WorkBuddy's Built-in Model Exclusively Supports Space Bunny

Tencent WorkBuddy announced that its built-in model exclusively supports Space Bunny. According to the introduction, Space Bunny is an anonymous Flash large model with extremely fast inference, strong coding capabilities, native support for text, image, and video input, adjustable thinking depth, and a context window of up to 1M. WorkBuddy has exclusive access in China, with a limited-time discount available from October 2 to October 7, 2026. On September 27, 2026, Space Bunny's Token call volume on OpenRouter was about 3.99 trillion, and on OpenCode about 8.3 trillion, both ranking first and topping the charts for three consecutive days. ^[2]

Apple Tightens macOS "Full Disk Access" Permissions

Apple recently announced that it will further tighten controls over the "Full Disk Access" permission in macOS and plans to add new security mechanisms to reduce the privacy risks that may arise when AI agents gain broad access to system data. Apple said that Full Disk Access was initially mainly intended to allow software such as backup tools to work properly, but as AI agents capable of autonomously operating computers become more widespread, the risks posed by this permission are rising markedly. Once an app obtains this permission, it can access large amounts of sensitive data, including files, mail, messages, and browsing history. Apple believes that when AI agents gain this level of system access, their potential impact differs from that of traditional apps, so users must be more clearly aware of what permissions they are granting to apps. ^[2]
