Paper:

Attention-head view

The attention-head view visualizes the attention patterns produced by one or more attention heads in a given transformer layer.

Attention-head view

BERT: [Notebook] [Colab]
GPT-2: [Notebook] [Colab]
XLNet: [Notebook] [Colab]

Model view

The model view provides a birds-eye view of attention across all of the model’s layers and heads.

Neuron view

The neuron view visualizes the individual neurons in the query and key vectors and shows how they are used to compute attention.
