In 2017, as a 20 year-old intern atGoogle Brain, Gomez was one of eight authors of the research paper "Attention Is All You Need",[9] which is credited with changing the AI industry and helping lead to the creation ofChatGPT.[3][4][10][11] The paper proposed a novel deep learning architecture called thetransformer, that enables machine learning models to analyze large amounts of data for patterns, and then use those patterns to make predictions while leveraging GPU parallelization. It has been commonly adopted for traininglarge language models and in the development ofgenerative AI.[3][12]
In the same year, Gomez founded FOR.ai,[7] a program to help researchers learn machine learning techniques in a collaborative format. An outgrowth of this project was Cohere For AI (now Cohere Labs), which released Aya, an open-source multilingualLLM.[13][14][15]
As a PhD student, Gomez worked as a machine learning researcher atGoogle Brain.[7] At that time, he co-authored the paper "One Model to Learn Them All" aboutmulti-task learning by a singleneural network.[6]
In 2019, Gomez left Google Brain to launch Cohere, an enterprise-focused company that helps businesses implement AI into chatbots, search engines, and other products.[3][4][16] As of Sept 2025, Cohere has raised about US$1.6 billion at valuation north of $7 billion, as Gomez leads the company as its CEO.[17]
Gomez was named to the 2023Time 100/AI list of the most influential people in the field of artificial intelligence.[3] He and his fellow Cohere founders Ivan Zhang andNick Frosst were named number 1 on 2023Maclean's AI Trailblazers Power List.[12]
In April 2025, Gomez was elected to the board ofRivian.[18][19]
