Technically, NCEP eliminated the MRF model 12 months ago.  At the same
time, they added resolution to the AVN and named it the GFS.  Currently,
NCEP still uses the old model designations in the GRIB files.  If you
look at the MRF grids out to 5 days, they match the equivalent AVN
grids.  So there is overlap.

I've gone to naming the grids GFS/AVN and GFS/MRF for both forward and
backward compatibility.
