It depends on the weather and the type of paint. OSB falls apart when it comes in contact near a lot of river. OSB also has closely of nooks and crannies that paint doesn't other get surrounded by, but water will sure find it. These answers are adjectives assuming that the appearance of the OSB is important. If it's on a shed, barn or something you newly don't care roughly it'll last as long as a year or two.
