Research Reveals Internal Workspace in Language Model Claude

Jul 6, 2026

AI Summary

A study has identified a unique internal structure in the language model Claude, termed the J-space, which functions similarly to a conscious workspace in the human brain. This J-space allows Claude to internally process concepts and influences its decision-making without directly outputting them, enhancing our understanding of its cognitive processes.

Researchers have discovered a collection of internal neural patterns in the language model Claude, called the J-space, which plays a significant role in its processing. These patterns are linked to specific words and allow Claude to think about concepts without verbalizing them.
The J-space operates similarly to the global workspace theory in neuroscience, where information becomes consciously accessible through a shared channel. It has strong connections to Claude's neural network, enabling it to broadcast information effectively.
Experiments show that Claude can manipulate its J-space, influencing its responses based on internal thoughts. For instance, when prompted to think of a sport, Claude's J-space revealed the word “Soccer” before it verbally responded.
The J-space allows Claude to perform complex reasoning tasks, such as solving multi-step math problems and recognizing injected thoughts, demonstrating its role in higher-order thinking.
While the J-space accounts for less than 10% of Claude's overall processing, it is crucial for tasks requiring deliberate reasoning, such as summarization and creative writing.
The findings suggest that Claude's internal processing is organized in a way that resembles human cognitive functions, providing insights into the model's capabilities and limitations.
