We propose nonlinear integral equations to describe the groundstate energy of the fractional supersymmetric sine-Gordon models. The equations encompass the N 1 supersymmetric sine-Gordon model as well as the φ<sub>id,id,adj</sub> perturbation of the SU(2)<sub>L</sub> × SU(2)<sub>K</sub>/SU(2)<sub>L+K</sub> models at rational level K. A second set of equations is proposed for the groundstate energy of the N 2 supersymmetric sine-Gordon model.
