The Gaia benchmark stars (GBS) are very bright stars of different late spectral types, luminosities and metallicities. They are well-known in the Galactic archaeology community because they are widely used to calibrate and validate the automatic pipelines delivering parameters of on-going and future spectroscopic surveys. The sample provides us with consistent fundamental parameters as well as a library of high resolution and high signal-to-noise spectra. This allows the community to study details of high resolution spectroscopy and to compare results between different survey pipelines, putting the GBS at the heart of this community. Here we discuss some results arising from using the GBS as main data source for spectral analyses.
