+/// Besides the pure text-to-speech models this covers the ones which answer in audio, such as
+/// gpt-audio and gpt-4o-audio-preview. Those do accept a text-only request, but they are made for
+/// spoken conversations, and the providers offering them keep them out of their chat model lists as
+/// well.
+///
+/// All three words are stated as name parts. The markers they replace carried a hyphen on one side
+/// to say the same thing, which caught one name these do not: Coqui's XTTS glues the word to an x.
+/// It is named outright rather than loosening all three into substrings, where "tts" would be three
+/// characters claiming every name that happens to contain them.
