I have invented much of the current revolution in large language models. Some of my inventions include:

• Transformer (2017)
(personally designed the multi-head attention, the residual architecture, and coded up the first better-than-SOTA working implementation)
• Sparsely-gated Mixture of Experts (2016)
• Mesh-Tensorflow (2018) - first practical system for training giant Transformers on supercomputers.
• T5 (2019)
• Major contributor to Google’s LaMDA dialog system, a project led by Daniel De Freitas, my now co-founder at Character AI.
