I posted this note to OpenAI.
Hey everybody, I have decided to leave OpenAI.
This was a very difficult decision as I have has such an incredible time at OpenAI. I got to join right before ChatGPT and helped build the post-training team from scratch with John Schulman and others. I feel so grateful to have gotten the opportunity to run the post-training team and help build and scale ChatGPT to where it is today. Right now feels like a natural point for me to explore new opportunities outside of OpenAI. This is a personal decision based on how I want to evolve the next phase of my career.
I am very grateful for all the opportunities OpenAI has given me and all the support I have gotten from OpenAI leadership such as Sam and Greg. I am in particular grateful for everything Bob has done and for being an excellent manager and colleague to me over my career at OpenAI. The post-training team has many many talented leaders and is being left in good hands.
OpenAI is doing and will continue to do incredible work and I am very optimistic about the future trajectory of the company and will be rooting everybody on.
