Elemedex: A pocket encyclopedia of AI architectures
Transformer
Evolution
The Eevee of AI: BERT, GPT, T5 and almost everything that came after evolved from its basic form. It was born to translate English into German and French, and it reads every word at once, the way a graphics card paints every pixel. Its motto fits in the title of the paper that introduced it.
