 The (static) IQ3 quants are no longer generated, as they consistently seem to result in *much* lower quality
 quants than even static Q2_K, so it would be s disservice to offer them.
 
 I specifically do not do Q2_K_S, because I generally think it is not worth it, and IQ4_NL, because it requires
 a lot of computing and is generally completely superseded by IQ4_XS.
 
-You can always try to change my mind.
