How to prompt CarperAI/openai_summarize_tldr_ppo model for summarization?

[bhavnicksm]

I have been trying to use the GPT-J model trained using this repo to see the difference it produces compared to normal SFT training. But the outputs it gives out haven't been that good.

I have tried temperature of [0.45,1] and followed the prompting that it was trained with in the "ARTICLE \nTL;DR:" form of prompts.

What hyperparameters and methods would give the best prompt for it?
