We present preliminary results of a model with two zones in order to study the production of high energy neutrinos at the prompt phase of gamma-ray bursts (GRB). Protons and electrons areinjected and accelerated in an acceleration zone limited by losses due to synchrotron, pγ, and pp processes. The secondary pions and muons also undergo energy loss and gain within the acceleration zone, and the escaping ones are re-injected in a second zone where acceleration no longer operates. We compute the neutrino output expected from both of these zones for generic GRB parameters, and integrate over redshift to obtain a diffuse neutrino flux which differs from previous calculations.
