Even if there's a party member at the C-level of some company making day-to-day business decisions, that doesn't necessarily mean they're carrying out detailed instructions from higher-ups in the party as opposed to following their own best judgment. The CCP generally doesn't micro-manage everything, but operates more in a "mission tactics"-like way, where the top level gives out a broad goal that gets condensed down into a slogan like "new productive forces," and interpreting and elaborating on the details is left to lower levels who seek to align their initiatives with the top-level goals (e.g. by describing AI as a "new productive force") and initiatives that appear successful will get blessed as official policy.

That different companies follow different strategies when it comes to model releases is clear evidence that there is no unified party line on this question yet.
