Why would they not release those models, since it would help them become profitable and beat the competition becoming the one company rule them all? Oh yeah, they are so dangerous. Well Anthropic revenue comes from only few big corporate customers, so just make them Golden Partners etc. and give them access to super-models. I doubt Google and Meta wants to crack web security.
Besides, if we start imagining super models US companies have in secret, why would we expect Chinese companies have them? Why would not Moonshot have their own super intelligence hidden in the cellar?
Vertical integration. They want to control all sectors, that's why OpenAI and Anthropic are slowly rolling out solutions for law, medicine, design and so on.
Why are you comparing these companies to previous tech companies (at least some of which have, by the way, been able to vertically integrate, like Salesforce and SAP) when AI is completely different from what came before? The real delusion must be thinking it's still a fad like Paul Krugman thought of the internet.
