We present our NextGen Model Atmosphere grid for low mass stars for effectivetemperatures larger than $3000\K$. These LTE models are calculated with thesame basic model assumptions and input physics as the VLMS part of the NextGengrid so that the complete grid can be used, e.g., for consistent stellarevolution calculations and for internally consistent analysis of cool starspectra. This grid is also the starting point for a large grid of detailed NLTEmodel atmospheres for dwarfs and giants (Hauschildt et al, in preparation). Themodels were calculated from $3000\K$ to $10000\K$ (in steps of $200\K$) for$3.5 \le \logg \le 5.5$ (in steps of 0.5) and metallicities of $-4.0 \le \mh\le 0.0$. We discuss the results of the model calculations and compare our results tothe Kurucz 1994 grid. Some comparisons to standard stars like Vega and the Sunare presented and compared with detailed NLTE calculations.Comment: ApJ, in press. 19 pages, also available at ftp://calvin.physast.uga.edu/pub/preprints/NextGen.ps.g
