I think Meta released the first open model, LLAMA, because they were behind OpenAI's ChatGPT charm offensive and saw the strategic value in giving away what they had spent millions making in order to erode a competitor's leading position.
Again Deekseek gave away what they trained, and claimed it hadn't been that expensive to train anyway, in order to erode the competitor's leading position.
But with time and regulatory capture this dries up. At least within America.
There's a good chance that Deepseek basically surprised the CCP too. But they have catapulted themselves to big national and international prominence. So going forward their future releases will very much be sanctioned by the Chinese government. So we'll only see further model giveaways if it's seen as strategically beneficial to devalue the competitors in America.
(Thinking further ahead: at some point soon there might be a LLM model or augmented model that is so good at getting probabilities right that it can 'outthink' a human. At that point, whichever billionaire controls it has zero upside in sharing it with anyone. It's purpose is no longer to fuel a funding bubble as they can instead use it to outthink humans for their own personal gain. They won't think 'this can outthink humans, so we can offer better clip art pickers and other AI integrations for the masses who might pay for access to it'. They will think 'how do I use this super intelligence to outsmart the humans currently voting in democracies or humans guiding the markets?)
No one in the West would use a Chinese model otherwise, so their best strategy is to destroy the US' ability to establish dominance and more unicorns.
Expect them to keep putting out models for free.
