Using the cluster expansion technique, we estimate, uniformly in the volume, the difference
between the quenched and annealed free energy in the high temperature phase of a
d-dimensional Ising spin glass model with Bernoulli couplings.

1. Introduction.
The study of disordered models in statistical mechanics has not yet reached the stage
of systematic treatment. Even physically, the systems described by these models are not yet
fully understood. For some of these models it has been rigorously proved [1-4] that in the
high temperature phase the quenched and the annealed free energy density coincide in the
thermodynamic limit. A question which naturally emerges from this result is the following:
does the coincidence quenched-annealed for high temperatures exists even in the short range
d-dimensional lattice theories? The answer seems to be negative at least in the models checked
up to now [5] . ...
