Ironically, for-profit Chinese companies have released far more Open AI than OpenAI. And they may be a key reason the for-profit OpenAI remains non-profitable.
It's worth noting I suspect a key reason Chinese companies are doing this is, in part, tacit encouragement and logistical enablement from the Chinese government. Playing spoiler by nerfing the valuations of over-inflated U.S. AI leaders is a decent strategy given the current GPU disparity.
