I review some marginal deformations of SU (2) and SL (2, ℝ) Wess‐Zumino‐Witten models, which are relevant for the investigation of the moduli space of NS5/F1 brane configurations. Particular emphasis is given to the asymmetric deformations, triggered by electric or magnetic fluxes. These exhibit critical values, where the target spaces become exact geometric cosets such as S 2 ≡ SU (2)/ U (1) or AdS 2 ≡ SL (2, ℝ)/ U (1) space . I comment about further generalizations towards the appearance of flag spaces as exact string solutions.
