Researcher
Alec Radford
Current role not listed
Radford led the original GPT and GPT-2 research, showing how learning to predict text could produce models that handle many language tasks.[1] He also helped create CLIP, which learns visual concepts from images paired with text, and Whisper, which transcribes and translates speech across languages[2]—bridging major advances in language, vision and audio.
