 # REM sleep priming anime
-A Python script that will generates the prompt unconditionally to increase the variation without any LLM bias; by Python's built-in Mersenne Twister (mt19937) PRNG in the random module. Iterated and tested with [cagliostrolab/animagine-xl-3.1](https://huggingface.co/spaces/cagliostrolab/animagine-xl-3.1) spaces. Not all the generated detail in the prompt works, this is due to the model lacking the dataset to understand it. And, not the script is not working. To use it, run the script and copy the printed output.
