OpenAI’s ChatGPT co-founder resigned the company just a few days after the company unveiled its latest AI chatbot, the GPT- 4o model. Ilya Sutskever, OpenAI’s co-founder and chief scientist — announced his departure on Tuesday after nearly a decade with the company. OpenAI unveiled its latest chatbot, the “GPT-4o” model, which has features for seeing, hearing, speaking, and reasoning, with a human-like response time. Sutskever and OpenAI co-founder, Mr Altman, played a central role in the dramatic firing and re-hiring of Mr Altman last November. Ilya Sutskever served on OpenAI’s board at the time and helped orchestrate the firing of Mr Altman.
