In past few months, I heard a lot about "AI coins" and I couldn't understand them correctly.
As far as I know, they are a very special form of utility token right? So what is their actual purpose? The holder can spend them on AI services? or they're just a way of finding investment or funds for AI projects? or both?
For specific projects (ChainGPT for example) I know that I can go with the whitepaper, but currently I just got a little confused about what makes them different from other utility tokens?

Regards.
