+  description: |
+    Grug 12B is kai-os's compact-reasoning fine-tune of Gemma 4 12B IT. It
+    targets shorter, denser reasoning traces while preserving constraints,
+    branching decisions, edge cases, and final-answer checks. This entry uses
+    Bartowski's Q4_K_M quantization and includes the multimodal projector for
+    Gemma 4 image inputs.
+
+    The model is experimental and its reported evaluation is a small local
+    math proxy rather than a broad benchmark. Review the upstream model card's
+    dataset provenance and `other` license before commercial or sensitive use.
