Scouting report
Transformer co-author who also built and released Tensor2Tensor, the open library that put a working transformer implementation in everyone’s hands within weeks of the paper, and later Trax. Moved to OpenAI to work on the reasoning-model line. The gap between publishing an architecture and everyone being able to run it was largely his to close.
Curator’s note
The paper made it famous; the repo made it everyone’s.
