Category: AI Research

Overview
Lucid is an instrument that allows users to observe the internal representations of AI models before they generate an output. By utilizing the Jacobian lens, it maps the concepts a model holds within its J-space, providing visibility into the model’s reasoning process.
How to use it?
Users enter a prompt into the interface to initiate a reading. The tool then displays the top concepts identified at each layer of the model, allowing users to track how thoughts evolve before the final response is spoken.
Features
Layer-by-layer concept visualization, Real-time thought tracking, Shareable session recordings, Support for open models, No account required, Rank tracking for pinned tokens
