Alec Radford (born 1993) is an American machine learning researcher known for DCGAN, CLIP and the original GPT models behind ChatGPT, developed largely at OpenAI.

I guess it's worth pointing out Alec Radford invented GPT, and he'd been working on GANs immediately prior to that.

It's interesting the central role of Alec Radford who not only was the lead author of CLIP but also created DCGANs and led the original two GPT papers.
