Very strange: When I turn the temperature to 1.25 to 1.5 I get much more interesting responses, but they are very ungrammatical with missing punctuation, misspelled words, dropped linking/transition words, etc.

When I try out finer gradations converging on 1 from > 1 and < 1 temperatures, responses < 1 tend to be more orderly and structured including bullet points, while > 1 are much more free form, and increasingly outright chaotic and incomprehensible at > 1.5.
