OpenAI-President Greg Brockman Returns in a Period of Transition and Turmoil
Greg Brockman, co-founder and president of OpenAI, has resumed his role after a three-month hiatus, a move that comes during a challenging time for the company.
With leadership exits and developmental obstacles tied to its next-generation AI model, Orion, Brockman’s return holds significance. On X, Brockman announced that his “longest vacation” was over, signaling his readiness to re-engage with OpenAI’s ongoing initiatives.
longest vacation of my life complete. back to building @OpenAI.

A Wave of Leadership Exits
OpenAI has experienced considerable leadership shifts this year, raising questions about its future direction. The departure of Chief Technology Officer Mira Murati in September, after more than six years of steering AI advancements such as ChatGPT, was a significant event.
Following her exit, Bob McGrew, who led research, and Barret Zoph, vice president of research, also stepped down. Earlier in the year, co-founder Ilya Sutskever left to launch Safe Superintelligence, an initiative focused on AI safety. His move was soon followed by John Schulman, another co-founder, who joined rival company Anthropic.
Adding to this list, Lilian Weng, vice president of research and safety, just recently announced her departure after nearly seven years of contributions. Weng’s legacy includes leading OpenAI’s Safety Systems team and enhancing the safety protocols for GPT-4’s launches. Her efforts also brought about the o1-preview model, known for resisting adversarial attacks and maintaining performance in high-stress scenarios.
Orion Model Faces Technical and Data Challenges
While OpenAI continues to expand its AI capabilities, the development of the Orion model has faced notable hurdles. Unlike the major strides seen in the leap from GPT-3 to GPT-4, Orion’s improvements are described as incremental.
Employees familiar with its testing reported that the advancements fell short of previous breakthroughs. CEO Sam Altman, addressing speculation, said that a rumored December release was not on the horizon, admitting compute constraints and rising operational costs in a Reddit AMA.
The scarcity of high-quality training data has emerged as a primary challenge. To fill this gap, OpenAI has increasingly relied on synthetic data—computer-generated datasets that simulate real-world text patterns.
While synthetic data offers a potential solution, ensuring it aligns with authentic data properties is crucial for effective training. This method reflects a broader industry trend as other major players, such as Nvidia, explore similar approaches.
Financial Strain and Compute Limitations
Developing models at the scale of Orion brings substantial financial and technical challenges. The training of GPT-4 alone reportedly cost over $100 million, underscoring the high stakes involved in model development.
Altman indicated that scaling up further would yield diminishing returns, suggesting that future progress might focus more on integrating models like o1, which recently showed promising results in reasoning tasks such as the SimpleBench benchmark.
Legal Battles and Industry Implications
As OpenAI navigates its internal challenges, it recently won a notable legal case that highlights the complexities surrounding content use in AI training. A lawsuit filed by Raw Story Media and Alternet Media, accusing OpenAI of removing copyright management information from articles during data collection, was dismissed by a federal judge.
The court found that OpenAI’s generative models synthesize data rather than replicate it verbatim, a ruling that aligns with similar cases, such as Microsoft’s defense of GitHub Copilot against copyright claims.
New Strategic Hires Amid Leadership Changes
Despite the departures, OpenAI has reinforced its team with strategic appointments, including Caitlin Kalinowski, a former Meta executive who led augmented reality projects. Her new role as head of robotics and consumer hardware at OpenAI signals potential diversification into AI-driven hardware.
This aligns with OpenAI’s collaboration with Jony Ive’s design firm, LoveFrom, on an upcoming AI device aimed at changing how users interact with technology.
Balancing Growth and Safety Amid Change
The exit of safety-focused leaders like Weng has sparked discussions about OpenAI’s commitment to balancing rapid expansion with the maintenance of robust safety practices.
During her tenure, Weng was instrumental in training models to handle sensitive data and building strong defenses against adversarial inputs. It remains to be seen if OpenAI can succeed in managing its dual objectives of growth and safety, especially as competition from rivals like Google DeepMind, Anthropic, Amazon, xAI and others intensifies.
