The equations of motion of 4d WZW models are equivalent to anti-self-dual Yang-Mills (ASDYM) equations which are, in the solit signature, reduced to various integrable equations such as KdV, Toda equations. On the other hand, 4d Chern-Simons (CS) theories give rise to various solvable models such as spin chain
