Anthropic's Transformer Circuits Thread published 'Verbalizable Representations Form a Global Workspace in Language Models' (July 2026). Using a new interpretability technique that surfaces concepts a model is poised to verbalize, the team found LLMs maintain a privileged set of internal representations available for report, modulation, and flexible reasoning — atop a much larger volume of automatic processing — an analogous functional split to conscious vs. unconscious human cognition. Measuring and intervening on these representations offers a window into the model's thought processes. Authors include Wes Gurnee and Jack Lindsey.
