Interesting. Can someone explain to me why 384 specifically? How did they arrive at that number?

It has to do with the architecture of the network used to create the embeddings. The embeddings is actually the output of the final layer of the model. The dimensionality is a function of the number of parameters in that layer.

Different models/architectures will produce different dimension embeddings.

It's not a power of two but is still a nice round number (0x180).
