%X We study the connection between inflation and supersymmetry breaking in the context of an O'Raifeartaigh model which can account for both hybrid inflation and a true vacuum where supersymmetry is spontaneously broken. For a weakly coupled inflaton field, the dynamics during the inflationary phase can be determined by the supersymmetry breaking scale M S ∼10 10  GeV, even if H I ⪢ m 3/2 . The spectrum of density fluctuations is then almost scale invariant, with a spectral index n−1= O (M G 2 /M P 2 ) . The mass parameter M G of the O'Raifeartaigh model is determined by the COBE normalization for the cosmic microwave background to be the grand unification scale, M G ∼10 16  GeV.
