Stellar Masses Are Not Randomly Sampled from "the" IMF Little clouds do not form high-mass stars. Histogram showing the number of stars at different stellar masses, form 0.1 solar masses ot 200 solar masses. A black line is labeled "100 little 2,000 Msun clouds". The distribution drops off sharply above 20 solar masses. A red line is labeled "1 big 20,000 Msun cloud" It also drops of at the high end, but not as sharply. It has stars out to 60 solar masses. A label notes "More high mass stars".

It can also create the correct distribution of binary stars with just turbulent fragmentation of the clouds of gas — meaning the stars have always formed a binary pair, they were not captured later.
STARFORGE also tells us that very small clouds will not form high-mass stars.
