In the Einstein--Gauss--Bonnet (EGB) gravity models, the slow-roll approximation was extended taking into account the first order of slow-roll parameter δ1=−2H2ξ′/U0 proportional to derivative of the Gauss-Bonnet coupling function ξ with respect to e-folds. Such extensions lead to the question about accuracy of potential reconstruction during attractors generalization in the EGB gravity. We reconstruct models in the both extended slow-roll approximations, compare them with the exact expressions and the standard slow-roll approximation.
