Jerry Tworek, vice president of research at OpenAI, has announced his departure from the company after seven years of service. In a note shared on social media platform X, Tworek stated his main reason for leaving is to pursue research that is "hard to do" at the current organization.
Key Achievements During Tenure
Tworek's contributions to OpenAI span numerous breakthrough developments in artificial intelligence research. His work encompassed several critical areas that shaped the company's technological advancement:
| Achievement Area | Details |
|---|---|
| Reinforcement Learning | Scaling RL on robots before mainstream adoption |
| Coding Models | Training first coding models that started LLM coding revolution |
| Scaling Research | Discovering chinchilla scaling methodology |
| Product Development | Overseeing GPT-4 and ChatGPT development |
| Reasoning Models | Building team for new paradigm of scaling training and inference compute |
"I've loved my time with this team. I got to work on scaling RL on robots before it was cool, training the first coding models in the world that started the LLM coding revolution, discovering chinchilla scaling before it was called chinchilla, working on gpt4 and chatgpt and most recently building a team that established new paradigm of scaling training and inference compute we commonly call reasoning models," Tworek wrote in his departure note.
Career Timeline at OpenAI
Tworek's journey at OpenAI reflects the company's rapid evolution in AI research and development:
| Milestone | Year | Role/Achievement |
|---|---|---|
| Joined OpenAI | 2019 | Research focus on scaling models and LLM foundations |
| Promotion | 2022 | Appointed Vice President of Research |
| Product Oversight | 2022-2025 | Management of ChatGPT and GPT-4 development |
| Reasoning Models | Recent | Led development of o1 and o3 models |
One of Tworek's most notable achievements includes the development of OpenAI's o1 and o3 models, which demonstrated doctorate-level performance in scientific subjects including physics, biology, and chemistry.
Context of Departure
Tworek's resignation occurs amid reports of changing research dynamics within OpenAI. According to a December 9, 2025 report from Wired, employees from the company's economic research team have cited concerns about the organization moving away from fact-based research. The report suggests OpenAI has become more restrictive regarding publication of research that may present AI in a negative economic light.
These developments coincide with OpenAI's transition from a non-profit model to a for-profit organization, along with reports indicating the company remains a loss-making entity despite significant financial obligations.
Research Impact and Legacy
Tworek emphasized his continued commitment to AI advancement despite his departure. "Together, we've made machine intelligence much more useful and reliable, and I'm a die hard ChatGPT reasoning model user," he stated in his farewell message. His work on scaling models and technical foundations of Large Language Models has contributed significantly to the current landscape of AI technology and applications.
