Altman has been the CEO of OpenAI since early 2019, so he has been there for the whole journey from GPT-2 to GPT-4/ChatGPT and the company's shift to mostly focusing on LLMs over RL/robotics/other stuff. I can't say I know much about the degree of his involvement, but my gut feeling is that he has been heavily involved in steering the company's direction and efforts.
