OpenAI Deliberately Limiting Internal Use of Models to Avoid Solving Research Problems
What was said
"We are trying to encourage people to not spend all their time just like going through all the mathematical open problems, physics problems, and just seeing, pushing the models to their limits to see what they can prove or disprove. Because we really think the focus should be on how do we make even more capable models? How can we get them out safely to the world as quickly as possible so that all the scientists in the world can use these models to solve the problems themselves?"
Brown disclosed that OpenAI is actively discouraging its researchers from using internal models to solve open mathematical and physics problems, despite having the capability to do so. The strategic decision prioritizes rapid model development over demonstrating current capabilities, revealing the lab's belief in significant untapped potential in existing systems.

About this episode
On this episode of No Priors, host Sarah Guo interviews Noam Brown, an OpenAI researcher who pioneered inference-time scaling techniques, about the broken state of AI model evaluations and the implications of large-scale test-time compute. Brown argues that current model benchmarking practices fail to account for the fact that modern AI capabilities are now a function of inference budget rather than fixed model properties, making comparisons misleading and safety evaluations inadequate. He revealed that existing responsible scaling policies and preparedness frameworks, developed during the ChatGPT era, don't address how much test-time compute should be allocated when evaluating dangerous capabilities, creating a critical blindspot as models can perform dramatically differently at $10 versus $10 million budgets. Brown disclosed that an internal OpenAI model recently disproved the Erdős unit distance conjecture at minimal cost, and that publicly available models like GPT-5.5 contain significant unexplored capabilities because the rapid release cycle means nobody runs models long enough to discover their limits. He revealed OpenAI is deliberately discouraging internal researchers from solving open problems in mathematics and physics to focus on building more capable models faster. The conversation explored recursive self-improvement, with Brown arguing against fears of overnight intelligence explosion because large-scale test-time compute creates a time bottleneck. He noted current models lack research taste and cannot yet fully replace researchers, though they dramatically accelerate certain tasks like code optimization. Brown predicted that within 6 to 12 months, models will be capable of completing PhD-level work zero-shot and emphasized the need for evaluation practices that plot performance against inference budget rather than reporting single benchmark scores.
Key takeaways
- Brown revealed that existing AI safety frameworks fail to account for test-time compute scaling, creating evaluation blindspots as model capabilities vary dramatically with inference budget from $10 to $10 million.
- An internal OpenAI model recently disproved the Erdős unit distance conjecture at minimal cost, and Brown said GPT-5.5 could likely achieve the same with $1,000 to $100,000 in scaffolded compute.
- OpenAI is actively discouraging researchers from using internal models to solve open mathematical and physics problems to prioritize rapid model development over demonstrating current capabilities.
- Nobody knows the capability ceiling of current AI models because the 2-3 month release cycle is faster than the weeks or months required to fully test model limits.
- Brown predicted models will complete PhD-level research projects zero-shot within 6 to 12 months based on GPT-5.5's poker bot development capabilities with minimal human guidance.
- Brown argued against overnight intelligence explosion scenarios because large-scale test-time compute creates an inherent time bottleneck that prevents instantaneous capability jumps.
- Current model benchmark grids are misleading because they don't control for test-time compute, with GPT-5.5 appearing only marginally better than 5.4 despite being substantially more efficient when compute is equalized.
