Nvidia Finds Harness, Not Model, Key to Stable AI Agents

Nvidia’s latest research shows that the framework—or harness—around an AI model can be more important than the model itself in ensuring reliable agent behavior. By fine‑tuning the harness, the company demonstrated that AI agents can perform well and avoid erratic or unsafe actions, even when the underlying model is not highly optimized for the task. The study suggests that careful system design and control mechanisms can mitigate risks associated with less capable models, offering a new path for building safer, more dependable AI applications.
