The AI features on Samsung's Galaxy S25 phones uses both on-device and cloud-based AI models, including the touted AI assistant.

This one's easy. Last year, the Galaxy S24 started at $799. This year, the Galaxy S25 starts at...$799. It's a wash, in other words. That said, it's possible that Samsung drops the price of the S24 after the launch of the S25, but until that happens, these two phones cost the same amount of money.
