# Artifact licenses and attribution

Licenses apply by component, not uniformly to this repository. Existing model cards, notices and provenance are retained.

- J-Lens tensors: sourced from [Neuronpedia Jacobian Lens](https://huggingface.co/neuronpedia/jacobian-lens), declared MIT by the upstream repository. The exact provider and available revision are recorded in the pack manifests. The upstream license declaration is included as `JLENS-SOURCE.md`. Tensors were converted or selected into browser-compatible packs; they are not a new lens fit.
- SAE tensors: derived from [Google Gemma Scope 2](https://huggingface.co/google/gemma-scope-2-1b-it), declared CC BY 4.0 upstream. Credit: Google DeepMind. Selected-layer tensors were repackaged for browser use; see the source and pack manifests. [CC BY 4.0 legal code](https://creativecommons.org/licenses/by/4.0/legalcode.en).
