Yes this is why I referred to 'months' and was downvoted by people who can't distinguish their politics from reality. You are restating exactly the text you are criticizing.
This is the nature of mechanical parrotlike repetition of propaganda:
a) You can have 'frontier' models with closed weights. Your sentence is basically a contraction within itself, again, the weight of ideology.
b) No one actually knows whether or not the closed weights of Bytedance are beyond all existing frontiers. Again the weight of ideology blinds you to the fact that the real 800 lb gorilla of Chinese Ai is more closed than Anthropic.
The parent made a totally coherent commment that China closing off their open weight models would cede the frontier (and majority of AI users worldwide) to the USA. Nothing you said counters that point.
1. Selling access to the US? 2. Ship more and better software? 3. Talk about it publicly?
If you had a secret AI better than anything currently available the mere mention of this would crater the US tech investment sentiment.
They could even host these Chinese models through AWS and sell at-cost inference on Bedrock and obliterate the US model companies.
