+  description: |
+    IndexTTS 2.5 is a multilingual text-to-speech model with zero-shot voice
+    cloning and emotion control, served by the audio-cpp backend. Supply a
+    server-local WAV path in the OpenAI `voice` field as the speaker reference.
+
+    This entry uses the published original-dtype GGUF. The package preserves
+    the source tensors without another quantization step, and audio.cpp records
+    the original-dtype IndexTTS2 path as passing its validation suite.
+
+    The bilibili Model Use License governs the model. Review its use,
+    redistribution, and large-scale commercial deployment terms before
+    installation.
