Experiment with a large-scale NLP text generation system. Pretrained online versions come and go; you could try 6b.eleuther.ai/ or transformer.huggingface. co/doc/distil-gpt2 or search for another one. Give the system some prompts and evaluate the text it generates. 

a. Is the generated text grammatical? 

b. Is it relevant to the prompt’s topic? 

c. Is it internally consistent from sentence-to-sentence and paragraph-to-paragraph?
