Capability Boundaries

Capability boundaries define the specific functional limits and scope restrictions placed on AI systems to ensure they operate only within intended use cases and cannot exceed their designed parameters. These boundaries are critical for enterprise AI governance because they prevent model drift, unauthorized applications, and potential harms that occur when systems are deployed beyond their validated performance ranges. By establishing and monitoring capability boundaries, organizations can maintain predictability, reduce liability, and ensure compliance with regulatory frameworks that require documented constraints on AI decision-making authority.

Training Data, Not Fine-Tuning, Sets the Hard Capability Ceiling for AI Models

Researchers from MPI for Intelligent Systems, ELLIS Institute Tuebingen, and ETH Zurich trained language models on a corpus filtered to U.S. elementary-school curriculum standards to test what limits model capability. Their findings show that scaling, fine-tuning, and in-context learning all fail to push performance meaningfully beyond what the pretraining data contained. The study provides empirical grounding for the principle that training data scope is the primary determinant of model capability.
