Samsung may eventually charge for its Galaxy AI features, and the company only promises they'll be free through 2025.
Samsung aren't saying that they will charge for Galaxy AI feature but the fine print says the following:
"Galaxy AI features will be provided for free until the end of 2025 on supported Samsung Galaxy devices. Different terms may apply for AI features provided by third parties."
Unfortunately even if you could distribute them here last I checked they don't have the US band support and going through FCC certification process takes time and money
