This article presents a new resource theory of generalized contextuality for GPT systems, framing noncontextuality as free resources and univalent simulations as free operations. A novel measure—“classical excess”—emerges to quantify contextuality, alongside the POM success probability. The authors explore how information erasure could explain fine-tuning in contextuality and propose experimental tests for heat dissipation. They also situate their framework within broader resource theories like entanglement, highlighting potential future directions in quantum information and foundational physics.
