They still have to develop the software.

The Samsung Galaxy Fold was released 7 years ago.

This is hilarious to me because all I hear from Apple fanbois about why iPhones are always years behind Samsung et al on new features is because “Apple don’t release things until they work properly”

They don’t need to, OpenAI and Anthropic are running at a huge loss to keep it cheaper to use them than to buy the comparable hardware required to replace them. The only way running open source models is cheaper is if you ignore hardware costs, or if you have a very specific and unusual usage pattern (i.e. constant 100% capacity, and not a clock cycle more or less), or if you go with another cloud provider who are also running at a loss.
