China has published more research papers than America with regards to AI training and inference optimizations and methods.

You are correct that they aren't completely open source, but the alternative is the American method, getting drip fed a ChatGPT OSS model every 12 months which cannot do basic programming.

>The only difference is the Chinese labs have allowed 3rd party inference providers run the proprietary models for them since they cannot do it themselves due to domestic GPU compute constraints.

I'm not sure this is entirely true either. Kimi K3 was released and for two weeks existed only via Moonshots API / Subscription. Openrouter reports 250B+ tokens a day for 11 days straight. I would assume they are processing over 1T tokens a day if you include direct API and their subscription.
