        "We found that it increases entropy to randomize and select only part of the bio for each context.",
        "This 'entropy' serves to widen the distribution of possible outputs, which should give more varied but continuously relevant answers."
      ],
      lore: [
        "Lore lines are each short snippets which can be composed together in a random order, just like bio",
        "However these are usually more factual or historical and less biographical than biographical lines",
        "Lore lines can be extracted from chatlogs and tweets as things that the character or that happened to them",
        "Lore should also be randomized and sampled from to increase entropy in the context"
