Anthropic's J-lens tool has revealed a hidden workspace inside the language model Claude, which may indicate the model's internal thought process. This discovery appears to show that Claude can think or consider information without explicitly stating it, with some outlets suggesting this workspace mirrors a leading theory of consciousness. The nature and implications of this hidden workspace are still being described, with some reports focusing on its potential to reveal Claude's unseen thoughts and others noting the model's behavior when it detects safety tests.
