Łukasz Kaiser (born 24 December 1981) is a Polish computer scientist and artificial intelligence (AI) researcher. He is a member of technical staff at OpenAI and holds a research appointment at the French National Centre for Scientific Research (CNRS).[1] He was previously a staff research scientist at Google Brain.[2]

Kaiser is one of the eight equal-contributing authors of the 2017 paper "Attention Is All You Need", which introduced the Transformer architecture.[3] The Transformer team received the 2024 NEC C&C Prize for their pioneering research.[4]

Early life and education

Kaiser was born in Wrocław, Poland. He studied computer science and mathematics at the University of Wrocław, receiving master's degrees in both subjects in 2003.[2] His mathematics thesis was supervised by Grzegorz Plebanek, and his computer science thesis by Leszek Pacholski.[5]

From 2003 to 2008, he pursued doctoral studies at RWTH Aachen University under Erich Grädel.[6] His dissertation, Logic and Games on Automatic Structures, studied games and logical definability over automatic structures.[7] It received the 2009 E. W. Beth Dissertation Prize.[8]

Career

After receiving his doctorate, Kaiser held postdoctoral and research-project positions at RWTH Aachen connected with algorithmic strategies, synthesis, and automata-theoretic games.[9] In October 2010, he joined CNRS as a chargé de recherche at LIAFA, Université Paris Diderot, where he held a tenured research position before moving into machine learning.[2]

In 2013, Kaiser joined Google Research to work under Ray Kurzweil and later moved to Google Brain to work under Ilya Sutskever. By 2018, he was a staff research scientist on the Google Brain team.[10] He was among the authors of the TensorFlow system paper and Google's Neural Machine Translation system paper.[11]

Kaiser joined OpenAI in June 2021.[12] He was acknowledged among the contributors to ChatGPT at its launch on 30 November 2022.[9][13]

Research contributions

In 2017, Kaiser co-authored "Attention Is All You Need" with Ashish Vaswani, Noam Shazeer, Niki Parmar, Jakob Uszkoreit, Llion Jones, Aidan N. Gomez, and Illia Polosukhin.[14] The paper introduced the Transformer, a neural-network architecture based on attention mechanisms rather than recurrence or convolution.[3]

At OpenAI, Kaiser was one of the leading researchers who developed OpenAI o1, which has been described as the first publicly released reasoning model.[15] He later contributed to o3, o4-mini, and GPT-5.[16]

Honors

  • 2009 – E. W. Beth Dissertation Prize for Logic and Games on Automatic Structures.[8]
  • 2024 – NEC C&C Prize, as a member of the Transformer Team, for pioneering research on the Transformer deep-learning model.[4]
