Скачать или смотреть Transformers explained | The architecture behind LLMs

All you need to know about the transformer architecture: How to structure the inputs, attention (Queries, Keys, Values), positional embeddings, residual connections. Bonus: an overview of the difference between Recurrent Neural Networks (RNNs) and transformers.
9:19 Order of multiplication should be the opposite: x1(vector) * Wq(matrix) = q1(vector). Otherwise we do not get the 1x3 dimensionality at the end. Sorry for messing up the animation!
