 Anthropic has released open-source code related to their J-space research.

According to the announcement, they have provided an open-source implementation of the core methods (the J-lens or Jacobian lens technique) in a dedicated code repository. Additionally, they partnered with Neuronpedia to host an interactive demo of these methods applied to open-weights models.

You can find the implementation details and tools via the links in their full research paper or explore the interactive version directly on the Neuronpedia demo.
