Researchers Use Jacobian Lens to Visualize LLM Internal States

repligate · x · 2026-08-05

AI researchers are utilizing mechanistic interpretability tools, such as Anthropic's Jacobian Lens and a custom variant called the k-lens, to inspect the internal states of large language models.

By applying these lenses to models like Qwen 3.6-27b, researchers can observe how the model processes complex texts like Finnegans Wake. This approach offers a deeper look into the rich internal representations and reasoning mechanisms within AI models.
