Writing in his bog, Zuckerberg argued that closing off AI models would not effectively prevent Chinese access, given their espionage capabilities, and would instead disadvantage  US allies and smaller entities.

He said that the Chinese were great at espionage, stealing models that fit on a thumb drive is relatively easy, and most tech companies are far from operating in a way that would make this more difficult.

“It seems most likely that a world of only closed models results in a small number of big companies plus our geopolitical adversaries having access to leading models, while startups, universities, and small businesses miss out on opportunities,” he said.

Constraining American innovation to closed development increases the chance that the US loses its leadership.

“Our best strategy is to build a robust open ecosystem and have our leading companies work closely with our government and allies to ensure they can best take advantage of the latest advances and achieve a sustainable first-mover advantage over the long term,” Zuckerberg said.
