Today’s artificial intelligence is often described as a “black box.” AI developers don’t write explicit rules for these systems; instead, they feed in vast quantities of data and the systems learn on their own to spot patterns. But the inner workings of the AI models remain opaque, and efforts to peer inside them to check exactly what is happening haven’t progressed very far.

Roughly in the middle of that arc, you'll find the Northern Crown constellation, which looks a bit like a smiley face.

When a cable or phone company's Internet service is too slow, too expensive, not deployed widely enough, or all of the above, local government officials sometimes decide to take matters into their own hands. Hundreds of municipal broadband networks have been built around the US as a result, including dozens that have started operating since 2021.

The companies, which include tech giants Amazon, Google, Meta, and Microsoft as well as Sam Altman-led OpenAI, Elon Musk’s xAI, and Chinese developer Zhipu AI, will publish frameworks outlining how they will measure the risks of their “frontier” AI models. The groups committed “not to develop or deploy a model at all” if severe risks could not be mitigated, the two governments said ahead of the opening of a global AI summit in Seoul on Tuesday.
