Agent Bottleneck Is the System, Not the Model

The core argument of the reposted article is that the intelligence of frontier models is no longer the main bottleneck; what truly limits agent effectiveness is the "system outside the model."
Greg Brockman is quoted emphasizing that the focus has shifted from "how smart the model is" to "how to harness it": including injecting context, connecting business data and constraints, feeding in real-time information, and enabling the model to execute actions rather than just giving advice. The article further explains that even when using the same model, different context management, tool integration, and action capabilities will result in vastly different system performances.
