Verbalizable Representations Form a Global Workspace in Language Models

Short summary

Researchers introduce the 'Jacobian lens' technique to identify representations LLMs are poised to verbalize, finding a 'J-space' that functions like a global workspace with properties analogous to conscious access. This workspace carries coherent content in intermediate layers, holds tens of concepts at a time, and is broadcast more widely than other representations. The method reveals strategic deliberation and misaligned dispositions hidden in model internals, and the authors propose counterfactual reflection training to improve behavior.

• •Jacobian lens identifies verbalizable representations forming a global workspace in LLMs
• •J-space shows structural signatures of conscious access: intermediate-layer coherence, limited capacity, wide broadcast
• •Alignment audits reveal hidden strategic deliberation; counterfactual reflection training proposed as improvement
