Dense Layer's Units

[Tonantzin_Real_Rojas]

In TF1 Course 1 and 2, when building a Neural Network, we used the Flatten layer and the first Dense layer with 512 units (or units > 100).

However, in Course 3 (NLP), besides using GlobalAveragePooling1D instead of Flatten as one of the layers, we also reduce to 6 units the first Dense layer.
Can someone help me understand why such a reduction happens?

Please print(model.summary()) to understand why Flatten layer is required. One thing that might help is to remove the flatten layer and see how the output changes.
