KPIC (the Keck Planet Imager and Characterizer) is a series of upgrades for the Keck II Adaptive Optics system and the NIRSPEC spectrograph to enable diffraction-limited, high-resolution (R>30,000) spectroscopy. KPIC’s use of single-mode fibers provides a substantial reduction in sky background and a stable line-spread function. In this paper we present recent upgrades deployed to KPIC in February 2024. These upgrades expand the science capabilities of the instrument to y-H bands, add laser frequency combs, and enhance the vortex fiber nulling mode. We show results from preliminary on-sky tests in the first few months of re-commissioning, along with the next steps for the instrument.
