  We present the results of searches for astrophysical neutrinos of few GeV
energy from compact binary mergers detected during the first months of the
fourth observing run of the LIGO, Virgo, and KAGRA interferometers. We describe
our method, based on a selection of $0.5-5$ GeV neutrino events in IceCube,
where we search for a statistically significant increase in the number of
low-energy candidate events detected around the compact binary merger time.
With these results, we constrain neutrino-emitting source populations. Finally,
we compare our results with constraints set by neutrino searches at $> 10$ GeV
energies and describe the complementarity of these low- and high-energy
searches.
