Abstract: The recent introduction of GDPval—a benchmark evaluating AI model performance on economically valuable real-world tasks—signals a fundamental shift in how organizations must approach work design, workforce planning, and operational strategy. This research examines the organizational implications of frontier AI models approaching human expert-level performance across 44 knowledge-work occupations spanning nine major economic sectors. Analysis reveals that AI capabilities are advancing linearly, with leading models now matching or exceeding human deliverables in approximately half of evaluated tasks while offering potential time and cost advantages when paired with human oversight. For organizations, these findings suggest an urgent need to move beyond conceptual AI strategies toward systematic work redesign, requiring recalibration of role definitions, capability development frameworks, quality assurance processes, and governance structures. This paper synthesizes evidence from GDPval findings with broader organizational research to provide practitioners with evidence-based approaches for redesigning work in an era where AI can competently perform complex, multi-hour knowledge tasks across professional domains. The analysis demonstrates that competitive advantage will increasingly depend not on whether organizations adopt AI, but on how effectively they reconfigure human-AI collaboration, redistribute cognitive labor, and build adaptive capabilities for continuous work evolution.
