I will discuss the synthesis of Planck LFI and HFI data reduction pipelines into NPIPE. NPIPE is a data reduction pipeline built on TOAST (time-ordered astrophysics scalable tools) and was chiefly operated at the US Department of Energy computing center, NERSC. The Planck team in Oslo played a critical part in the development of NPIPE and the production of the last public data release (PR4) of Planck in 2020. In the spirit of Nordic cooperation, the pipeline employs the Helsinki-developed mapmaking code, MADAM. I will conclude with a preview of a pending release of polarization maps derived from the nominally unpolarized Planck 857GHz channel using NPIPE.
