+/// carries the name of the model it was trained from, so the Mistral rules answer for it and tell
+/// it that it chats and calls functions. Saying which name means what it says is cheaper than
+/// teaching every family whose weights somebody built an embedder from.
+///
+/// The E5 part is the whole statement: the rest of the name says nothing about what the model does.
