An overview of the experimental results of the Baikal-GVD gigaton-scale deep-sea neutrino telescope during its construction from 2016 to the present, 2025 is presented. According to Baikal-GVD data, over 6 years of observations, the presence of an astrophysical component in the diffuse neutrino flux, measured with cascades in the TeV–PeV energy range, has been confirmed at a level of more than 5σ. We discuss the spectral analysis of the sample of high-energy neutrinos, the galactic origin of neutrinos with energies above 200 TeV, the first results in upper limits on the flux of cosmogenic neutrinos, and real-time data analysis in frame of multimessenger program.
