have this block length and we'll get into the block length in one second but then you can see that their window size is three times the block length the number of random tokens is three times the block length and the number of global tokens is two times the block length so that results in eight times b so 8 times 64 is you know can i calculate this or am i stupid uh it's 512 yes actually calculated this before so this is 512 tokens so you know you you go from from bert that has 512 tokens and attends to 512 tokens to also
