AI / Large Models

Anthropic announced the increase of the known lower bound of the Riemann Hypothesis from 41.6% to 67.2%

While the hypothesis has not yet been proven, this is the first time a large model has raised the lower bound in pure mathematics frontier issues, demonstrating a leap in reasoning capability.

Hot Debate: The community is arguing whether this is "true mathematical intuition" or probability fitting, but no one can deny that the figure itself is quite alarming.

OpenAI locks down the next-generation model GPT-6 (Astra), triggering internal alerts for the first time due to cybersecurity capabilities

The concurrently launched GPT-5.6-Cyber can already perform advanced cybersecurity tasks, while Astra directly crossed the security red line.

> Sharp Comment: On one hand arming the models with weapons, on the other fearing they might actually fire, AI companies are twisting themselves into pretzels.

US-Iran talks stall, the Strait of Hormuz remains blocked, international crude oil rises over 2%, and spot gold breaks through $4400 to hit a new high since June

Trump claims that the US military has controlled the strait and cleared mines, demanding reparations from Iran; Iran, in turn, offers to restore passage on the condition of a maritime service fee, but the conditions of both sides are vastly different, complicating the deadlock.

Today's Dark Line

The gunfire in the Strait of Hormuz has pushed oil and gold prices back into the spotlight, while the intensity of the arms race in Silicon Valley's AI sector is no less than that of geopolitical conflicts—NVIDIA's $500 billion computing power financing plan coincidentally occurred on the same day that crude oil supply was cut off. What's even more intriguing is that OpenAI quietly locked down the next-generation model Astra, indicating that what is most valuable is not energy, but the capability of independent execution of cyberattacks. Energy, computing power, and security, three seemingly unrelated elements, today have twisted into a tightly stretched string.
