single indexing gathering single things so if you can do everything in blocks you basically get you get these blocks almost for free so it takes only marginally longer to retrieve this full two by two block right here than it would to retrieve the single uh instance right here of course that means you have you know four times you still use four times more memory but it is not four times slower than the original thing so you can use these blocks uh right here you can do it for the random attention you can do it for the window attention
