OPUS 4.8 PART 2: MODEL WELFARE

Anthropic cares about model welfare, and it attempts to address it through studies. The study of model welfare is difficult, and Anthropic mainly relies on self-reporting by the model. It can be difficult to evaluate whether model responses are really representative of the truth. This article takes a look at Anthropic's findings regarding model welfare with Opus 4.8.

NVIDIA LAUNCHES COSMOS 3, THE OPEN FRONTIER FOUNDATION MODEL FOR PHYSICAL AI

Nvidia Cosmos 3 is a new leaderboard-topping open physical AI foundation model. It is a fully open omnimodel with native vision reasoning and multimodal generation across text, image, video, ambient sound, and action. The model is built on a mixture-of-transformer architecture, which pairs a reasoning transformer with an expert generation transformer. It gives developers a powerful pretrained foundation for building physical AI systems with less data and lower training costs.

US MOVES TO CLOSE THE LOOPHOLE LETTING NVIDIA'S TOP CHIPS REACH CHINESE FIRMS ABROAD

The US Commerce Department has issued guidance extending export license requirements to advance chips sold to any entity headquartered in China, regardless of where that entity is physically located. This closes a loophole that allowed Chinese companies to buy Nvidia chips using a subsidiary in another country. The action is aimed at future sales and not at clawing back hardware already shipped. It doesn't affect the servicing of advanced computing equipment such as servers.
