Abstract

With over a million subscribed users, GPT-3 and related models have received a lot of press coverage and public attention. Much like a flashy Porsche driving down the Autobahn, these models look impressive, and are performing well. However, it is only a matter of time until they are overtaken by a much larger supercar. And that vehicle is already rapidly approaching. Google Pathways was announced at the end of 2021, and we are seeing several of its components in 2022: beginning with PaLM, PaLM-Coder, Parti, and Minerva. While all of these models are closed—only available for Google’s internal research—it is anticipated that a future Pathways model will be publicly released. This report explores the accomplishments of the Pathways models so far, with PaLM and its related language models already at more than triple the size of GPT-3.
