Nvidia's own sizing guide argues most inference budgets are wrong in the first spreadsheet, not the second data center. The interesting admission is that smaller models are usually the answer.
OpenAI says Astra is the first model to hit the Critical cybersecurity threshold in its Preparedness Framework — and that it found two zero-days during evaluation. It is shipping anyway, with friction.
DLSS 5 ships with one supported game, a 50 to 60 percent performance cost, and 6x frame generation as the price of entry. That is a tech demo with a release date.
A vendor case study with a useful admission buried in it: Gilbert + Tobin got 87 percent active usage by refusing to set usage targets and sending trainers into individual team meetings.
Apple's trade-secret fight with OpenAI is widening from employee access to alleged evidence destruction, putting offboarding controls and discovery under scrutiny.
Hugging Face is packaging WebGPU operations as versioned, testable Hub artifacts, betting that browser inference needs a shared kernel supply chain as much as it needs models.
The Pentagon is putting tailored versions of ChatGPT and Grok behind a secure portal, making commercial frontier models part of routine defense work without consumer data channels.
