CEO OpenAI · ChatGPT
Sam Altman
b. 1985 · American
Co-founded OpenAI in 2015 (initially with Elon Musk, Reid
Hoffman, Ilya Sutskever). In 2019 he restructured the company
from a non-profit into a hybrid model in order to bring Microsoft
on board as an investor.
Previously president of the startup incubator Y Combinator. Not
primarily a scientist but a strategist - his talent is turning
big vision into capital and attention. In November 2023 he was
briefly fired by the board and brought back after five days -
still one of the strangest tech dramas of the decade.
CEO Anthropic · Claude
Dario Amodei
b. 1983 · American
A physicist; in 2021 he left OpenAI to found Anthropic
- together with his sister Daniela. The reason for the break:
concerns that OpenAI was sacrificing safety for speed. Anthropic
positions itself as the "safety-oriented" AI lab.
His essay "Machines of Loving Grace" (2024) is the most
detailed positive vision of the future any AI head has ever
published. Long a backstage figure, he has been publicly present
since 2024.
CEO Google DeepMind · Nobel Prize
Demis Hassabis
b. 1976 · British
Chess prodigy, game designer, neuroscientist. Founded DeepMind in
2010, sold it to Google in 2014. His lab delivered
AlphaGo (victory over the Go world champion),
AlphaFold (solving the protein-folding problem)
and many other breakthroughs.
Nobel Prize in Chemistry 2024 for AlphaFold.
Regarded as the "most scientific" of the lab heads - his explicit
goal is to use AI to solve science itself, not to build chatbots.
Co-founder OpenAI · returned 2025
Ilya Sutskever
b. 1986 · Russian-Israeli-Canadian
A Hinton student, co-founder of OpenAI, for years its chief
scientist. Regarded as one of the most influential minds behind
ChatGPT. In November 2023 he was central to the brief ousting of
Altman - over safety concerns.
He left OpenAI in 2024 and founded Safe Superintelligence
Inc. (SSI) - a lab with a single goal: to build safe
superintelligence, with no commercial distractions.
Teacher · Explainer · Tesla alumnus
Andrej Karpathy
b. 1986 · Slovak-Canadian
One of the founding members of OpenAI, later head of Tesla's
Autopilot development, back at OpenAI in 2023, gone again in 2024.
He currently works independently in education - his YouTube
channel with explainer videos on language models is the most-used
learning resource for AI engineers worldwide.
In 2025 he founded the learning platform Eureka Labs.
He regularly coins terms the field then adopts - for example
"Software 2.0" for AI-based programs.
Ex-CTO OpenAI · Thinking Machines
Mira Murati
b. 1988 · Albanian-American
Was CTO of OpenAI throughout the entire ChatGPT era. In November
2023 she served for a few hours as interim CEO when Altman was
removed. She left OpenAI in 2024.
In 2025 she founded Thinking Machines Lab - with
almost 800 million dollars of seed funding, the largest first
round in the industry's history. Focus: AI that works together
with people rather than replacing them.
CEO Microsoft AI · DeepMind alumnus
Mustafa Suleyman
b. 1984 · British
Co-founder of DeepMind (2010), later co-founder of
Inflection AI (the chatbot "Pi"). In 2024 he and
his team were "poached" by Microsoft - Inflection effectively
dissolved. He now leads Microsoft's AI division.
His book "The Coming Wave" (2023) is one of the most
important books for strategically situating the next ten years -
arguing that AI and synthetic biology together will shift all
existing balances of power.
CEO xAI · Grok · Tesla · X
Elon Musk
b. 1971 · South African-American
Co-founded OpenAI (2015) and left in 2018 after a falling-out. In
2023 he founded xAI and builds the chatbot
Grok, which is integrated into X (formerly
Twitter). Since 2024 he has been fighting OpenAI in several court
cases.
His position is contradictory: in 2018 he was still a loud warner
against AI risks, today he builds his own models as fast as
possible. He acts on the field mainly as a political and economic
amplifier, less as a scientist.
Visionary · Singularity
Ray Kurzweil
b. 1948 · American
Inventor, futurist, Director of Engineering at Google since 2012.
In 2005, in "The Singularity Is Near", he predicted that
AI would reach human intelligence by 2029 and far surpass it by
2045 (the singularity).
Long mocked as an outsider, since 2023 many regard him as a seer.
In 2024 his update book "The Singularity Is Nearer". He
sticks to his original forecasts unchanged.
DeepSeek · China
Liang Wenfeng
b. 1985 · Chinese
Founder and CEO of DeepSeek - the Chinese lab
that made headlines worldwide in January 2025 with the R1 model.
R1 was reportedly trained for a fraction of the cost of Western
models and challenged the assumption that only hyperscalers can
build AI.
Earlier career in the quant hedge fund world. He stands for the
non-Western side of AI development, which the West long
underestimated.
