Most widely used AI models come from American and Chinese companies

the gist

Dozens of companies around the world build large AI models, but a small number of them account for most of the systems people actually use. Those flagship models come mostly from US labs and Chinese developers. Training a frontier model takes huge amounts of computing power, specialist talent and data, which keeps the field concentrated. That concentration shapes which languages, values and default answers reach billions of users.

how it works

Large AI models are trained on enormous datasets using vast clusters of specialised chips, a process that costs huge sums. Only a few organisations can afford that scale, so the most capable systems tend to come from a handful of well-funded labs.

so what

Whoever builds the most-used models sets the defaults for search, writing and software tools. Knowing where these models come from helps explain the geopolitics of AI and why countries worry about depending on foreign systems.

Hampi was once one of the world's largest cities, until its Vijayanagara capital was destroyed in 1565

the gist

Hampi is a UNESCO World Heritage Site in Karnataka, India, with more than 1,600 surviving remains spread over 4,100 hectares. It was the capital of the Vijayanagara Empire from 1336 to 1565. Travellers from Persia and Portugal described it as a prosperous, wealthy and grand city with temples, markets and farms along the Tungabhadra River. By 1500 it was estimated to be the world's second-largest city after Beijing, and probably India's richest at the time. In 1565 a coalition of Muslim sultanates defeated the Vijayanagara Empire, its capital was conquered and destroyed, and the city was left in ruins. Hampi remains a religious centre, with the active Virupaksha Temple at its heart.

how it works

The city was built around a fortified core with temples, markets and water structures along the river, supplied by an extensive network of roads and waterworks. When the empire fell, the city was not rebuilt, so its stone monuments were left standing.

so what

Hampi shows how quickly a great city can vanish after a military defeat, and how a ruined capital can remain sacred. Its ruins give historians a view of medieval South Asia that few other sites can match.

fun fact

The name Hampi comes from Pampa, an old name for the Tungabhadra River.

False allegations about Singapore’s hand in Indonesia’s markets and a made-up meeting

from CNA

CNA Verify has found close to 400 posts pushing falsehoods tying Singapore to Indonesia’s stock market rout and to a secret meeting that never took place. Together, they drew nearly 12 million views, and some were circulated by accounts that appeared to be working in concert, across multiple social media platforms.

Here’s how the disinformation campaign targeting Singapore was uncovered.
