over here uh it doesn't it doesn't matter too much for our discussions but either you you know have a reference input or you have you know this kind of same input all the way and then what you do is you use three different heads or you know three different matrices to transform that input into queries keys and values so i often conceptualize this as you have kind of your input set and each of the input sets outputs a key and also each one which would be a vector and also each one outputs a query so i often draw this here
