Just a cursory probing of deepseek yields all kinds of censoring of topics. Isn't it just as likely Chinese sponsors of this have incentivized and sponsored an undercutting of prices so that a more favorable LLM is preferred on the market?
Think about it, this is something they are willing to do with other industries.
And, if LLMs are going to be engineering accelerators as the world believes, then it wouldn't do to have your software assistants be built with a history book they didn't write. Better to dramatically subsidize your own domestic one then undercut your way to dominance.
It just so happens deepseek is the best one, but whichever was the best Chinese sponsored LLM would be the one we're supposed to use.
