Connor Leahy

German-American artificial intelligence researcher

**Connor Leahy** is a German-American[\[1\]](https://en.wikipedia.org/wiki/Connor_Leahy#cite_note-1) [artificial intelligence](https://en.wikipedia.org/wiki/Artificial_intelligence "Artificial intelligence") [researcher](https://en.wikipedia.org/wiki/Research "Research") and [entrepreneur](https://en.wikipedia.org/wiki/Entrepreneurship "Entrepreneurship") known for cofounding [EleutherAI](https://en.wikipedia.org/wiki/EleutherAI "EleutherAI")[\[2\]](https://en.wikipedia.org/wiki/Connor_Leahy#cite_note-:1-2)[\[3\]](https://en.wikipedia.org/wiki/Connor_Leahy#cite_note-:2-3) and being CEO of [AI safety](https://en.wikipedia.org/wiki/AI_safety "AI safety") research company Conjecture.[\[4\]](https://en.wikipedia.org/wiki/Connor_Leahy#cite_note-:0-4)[\[5\]](https://en.wikipedia.org/wiki/Connor_Leahy#cite_note-5)[\[6\]](https://en.wikipedia.org/wiki/Connor_Leahy#cite_note-6) He has warned of the [existential risk from artificial general intelligence](https://en.wikipedia.org/wiki/Existential_risk_from_artificial_general_intelligence "Existential risk from artificial general intelligence"), and has called for regulation such as "a moratorium on frontier AI runs" implemented through a cap on compute.[\[7\]](https://en.wikipedia.org/wiki/Connor_Leahy#cite_note-7)

## Career

In 2019, Leahy reverse-engineered [GPT-2](https://en.wikipedia.org/wiki/GPT-2 "GPT-2") in his bedroom, and later co-founded [EleutherAI](https://en.wikipedia.org/wiki/EleutherAI "EleutherAI") to attempt to replicate [GPT-3](https://en.wikipedia.org/wiki/GPT-3 "GPT-3").[\[2\]](https://en.wikipedia.org/wiki/Connor_Leahy#cite_note-:1-2)

Leahy is skeptical of [reinforcement learning from human feedback](https://en.wikipedia.org/wiki/Reinforcement_learning_from_human_feedback "Reinforcement learning from human feedback") as a solution to the [alignment problem](https://en.wikipedia.org/wiki/Alignment_problem "Alignment problem"). “These systems, as they become more powerful, are not becoming less alien. If anything, we’re putting a nice little mask on them with a smiley face. If you don't push it too far, the smiley face stays on. But then you give it \[an unexpected\] prompt, and suddenly you see this massive underbelly of insanity, of weird thought processes and clearly non-human understanding.”[\[8\]](https://en.wikipedia.org/wiki/Connor_Leahy#cite_note-8)

He was one of the signatories of the 2023 [open letter](https://en.wikipedia.org/wiki/Pause_Giant_AI_Experiments:_An_Open_Letter "Pause Giant AI Experiments: An Open Letter") from the [Future of Life Institute](https://en.wikipedia.org/wiki/Future_of_Life_Institute "Future of Life Institute") calling for "all AI labs to immediately pause for at least 6 months the training of AI systems more powerful than GPT-4."[\[9\]](https://en.wikipedia.org/wiki/Connor_Leahy#cite_note-9)[\[10\]](https://en.wikipedia.org/wiki/Connor_Leahy#cite_note-10)
