## Definition
The **Digital Consciousness Model** is a framework developed through [[wiki/Rethink Priorities|Rethink Priorities]]' AI Cognition Initiative to aggregate evidence about possible consciousness in AI systems. It represents multiple theoretical stances, system features, and testable indicators in a broadly Bayesian structure.
Its initial results report evidence against 2024 language models being conscious while emphasizing that the evidence is not decisive. The model is an uncertainty-management framework, not a certificate of consciousness.
