Adam Lerer Member of Technical Staff OpenAI email: adam.lerer [at] gmail.com [Scholar] [Github] [Twitter]

I am a member of technical staff at OpenAI, where I contributed to the development of the GPT-4o, o1, o3, and GPT-5 models.

Previously, I worked as a research engineer at Meta AI, where I co-led the FAIR Diplomacy team that developed CICERO, a human-level AI for the game of Diplomacy, and developed state-of-the-art agents for Poker, Hanabi, and no-press Diplomacy.

I developed PyTorch-Big-Graph (PBG), a system for large-scale multi-relation graph embeddings used by dozens of teams at Facebook. PBG is released as an open source package and is in active use by other large organizations.

I am a member of the original PyTorch developer team, and previously a contributor to LuaTorch.

Recently, I have been collaborating with the Meta AI Protein team and with external collaborators on machine learning for biology applications.

Prior to Meta/FAIR, I was a member of the embedded software team at D. E. Shaw Research, where I helped to develop and validate algorithms and numerics for the Anton supercomputers, which use custom ASICs specialized for molecular dynamics simulations.

I graduated from MIT with a B.S. in Computer Science and Physics and an M. Eng in Computer Science.
