What was Schulman’s role at OpenAI?
TechCrunch described Schulman as having led OpenAI’s reinforcement training organization. That group fine-tuned generative AI models to follow human instructions. This is useful context for his work, but it should not be read as a complete account of his contributions to OpenAI.

Did OpenAI name a replacement?
OpenAI had announced Jakub Pachocki as chief scientist in May 2024, when it also announced Ilya Sutskever’s planned departure. That announcement preceded Schulman’s departure by several months; it does not establish that Pachocki was appointed as Schulman’s replacement. OpenAI’s May 14, 2024 announcement concerns Sutskever and the chief scientist appointment, not Schulman’s August move.

Why did Schulman leave?
The reports and company announcement identified his departure and destination, but the material available here does not substantiate a detailed personal explanation from Schulman. It would be speculation to assign him a motive or present the move as evidence of a particular dispute.
What does “other defectors” mean in the headline?
The reporting supports that Schulman joined Anthropic and characterizes Anthropic as a rival. It does not, on its own, provide enough detail to explain the headline’s reference to “other defectors” as a verified account of the company’s founders or former OpenAI employees. That phrase should be treated as headline framing, not as a conclusion established by the cited reports.
