GPT3 is already trained. You can't re-train it yourself. You can give it poetry as input though, and its output should somewhat resemble poetry. Here's my exanple from another thread. The first three lines are input (Theo's poetry): . >**It comes in three parts, like all things.** >**Why God chose three as his number is anyone's guess.** >**A Mystery of the Universe.** >Mysteries of the human race. >Sciencings of all kinds, mine included. >Even, I have long thought, of geography. >Three concentric rings around the Earth, one extending north and south, one east and west, and one in the middle. >This part is the deep ocean. >The Pacific Ocean. >A sign of that spiritual connection, of closeness, is that God lives in the middle. >I could write a story about the middle. >L. A. as the heart and the three concentric circles as the legs, circling. >Pico de Avila.
