+    Shieldstral 1.0 3B is Mistral AI's compact, policy-adaptive multimodal safety
+    classifier. It evaluates text, images, or combined inputs against a
+    natural-language safety policy and answers yes or no. The model supports
+    twelve languages and a recommended context length of up to 32K tokens.
+    This entry uses the Q4_K_M GGUF quantization and includes the Pixtral vision
+    projector.
