A token is an integer. An embedding converts that integer into a dense vector of size d_model (e.g., 512). Since attention mechanisms are permutation-invariant, we must inject position information. You can also use popular libraries like Hugging

(from the original "Attention is All You Need" paper) are a classic choice: 512). Since attention mechanisms are permutation-invariant
