HE CO-AUTHORED THE TRANSFORMER. THEN BUILT COHERE

Gomez co-authored 'Attention Is All You Need' as a Toronto undergrad — the 2017 Google paper whose title became shorthand for the Transformer, the architecture behind every modern frontier model. He then turned it into Cohere, an independent Canadian lab selling enterprise and sovereign deployments.
