    Abstract. We give a coset realization of the vertex operator algebra M(1) + with central charge ℓ. We realize M(1) + as a commutant of certain affine vertex algebras of level −1 in the vertex algebra L (1)( − C ℓ 1 2Λ0) ⊗ L (1)( − C ℓ 1 2Λ0). We show that the simple vertex algebra (−Λ0) and find the corresponding L
