OpenAI co-founder Ilya Sutskever departs ChatGPT maker

“OpenAI would not be what it is without him,” OpenAI CEO Sam Altman wrote in a message to the company, which OpenAI posted on its blog.

Microsoft-backed OpenAI makes the popular ChatGPT chatbot, which sparked a race among the world’s largest tech companies for dominance in the emerging generative AI field.

Jakub Pachocki will be the company’s new chief scientist, the company said on its blog.

Pachocki has previously served as OpenAI’s director of research and led the development of GPT-4 and OpenAI Five.
