Handling Long Text Inputs with text-davinci-003

I’m having trouble getting the outputs I need from my current workflow. I’m taking long interviews (about 10,000 tokens) chunking and summarizing the with text-davinci-003, then recombining it into a single 900 token (approximate) summary. I then ask the model to write a story about the subjects life about 4-5 paragraphs long “using the following information”. If I pass this prompt with summary to chatGPT I more or less get what I want, but often times I’ll get nothing from the api or just a single sentence. Is there any trick to getting text-davinci-003 to create a story from a large amount of data that you present in the prompt?
