According to Epoch AI, a nonprofit dedicated to AI research, enhancements in reasoning AI models may encounter limitations soon, with anticipated decelerations within the next year. Reasoning models, like OpenAI’s o3, have outperformed benchmarks assessing mathematical and programming skills. However, these advancements rely on increased computational power, and that prolongs task completion times.
In order to train its reasoning models, OpenAI invested around ten-times more computational power in training o3 compared to o1. Future commitments from OpenAI suggest an increased focus on reinforcement learning backed by even greater computational support. Nevertheless, Epoch emphasizes that there remains a ceiling on the computational resources available for reinforcement learning, and observes that while performance gains from traditional AI training are presently quadrupling each year, those derived from reinforcement learning are surging tenfold every three to five months. Therefore, the training of reasoning models could align with overall advancements in AI by 2026.
Epoch’s conclusions hinge on various assumptions from industry experts, pointing out that scaling reasoning models could encounter obstacles beyond just computational capacity, such as the costs associated with research and development. Ongoing research expenses might impede the scaling of reasoning models, potentially falling short of expectations. Any indicators suggesting that reasoning models may soon hit a threshold could raise concerns in the AI sector, which has heavily invested in their advancement. Notably, research now indicates that despite high operational costs, reasoning models often manifest significant shortcomings, including a greater likelihood of inaccuracies compared to traditional models.
