## Scientists Explore Consciousness in Large Language Models
- Initial assessments in 2022 indicated a low probability of consciousness in large language models.

The Digital Consciousness Model, launched in January 2026, provides a framework for evaluating AI consciousness against multiple theories.
Scientists are actively investigating whether large language models (LLMs) could possess consciousness, a complex question with no single accepted definition of consciousness itself. Research in this area involves evaluating LLMs against various established theories of consciousness.
One notable framework for this assessment is the Digital Consciousness Model (DCM), introduced in January 2026. Developed by the AI Cognition Initiative at Rethink Priorities, the DCM aims to systematically and probabilistically evaluate evidence for consciousness in AI systems. This model incorporates a range of leading theories of consciousness, acknowledging the ongoing disagreement among experts about its nature and necessary conditions.
Initial findings from the DCM suggest that the evidence against 2024 LLMs being conscious is not decisive, though it is much weaker than the evidence against consciousness in simpler AI systems. When LLMs from 2022 were assessed, their average scores against ten theories of consciousness generally fell below 20%. However, for certain theories, such as displaying complex cognitive abilities, LLMs have shown significantly higher scores in later models.
The debate over LLM consciousness highlights the challenges in defining and measuring consciousness, especially in non-biological systems. While some theories, like Integrated Information Theory (IIT), suggest that current LLMs lack the necessary structural and dynamic properties for consciousness, other perspectives continue to explore the potential for consciousness to emerge from complex information processing in AI. Researchers emphasize the importance of rigorous, empirically grounded approaches to assess AI consciousness as these systems continue to evolve.
