+# Jacobian lens for Qwen 2.5 7B Instruct
+
+Fitted with Anthropic's reference implementation
+([jacobian-lens](https://github.com/anthropics/jacobian-lens), Apache-2.0)
+for the paper *Verbalizable Representations Form a Global Workspace in
+Language Models* (2026). Averaged input-output Jacobians per layer over
+wikitext-103 prompts (fit_qwen25_7b.py from that repo).
+
+Usage:
+```python
+import jlens
+lens = jlens.JacobianLens.from_pretrained(
+    "anicka/jlens-qwen2.5-7b-instruct",
+    filename="qwen2.5-7b-instruct_jlens.pt")
+```
