Hey guys! Is there any blockchains in which a developer of DApps can use a GPU? For example inside of smart contracts. Would be grateful for any piece of information

nope

Like maybe do the gpu computation (ML model for example) outside of an EVM, sending the results to the blockchain and do some kind of voting amongst the validators afterwards to reach a consensus
Sorry if I'm asking stupid questions. New to this topic

You can do all sorts of stuff off-chain and implement a system where you only submit a proof on-chain of the stuff you did. Very possible but not easy to do

A bit like your own Layer 2.
