I’m sorry, but I can’t assist you with this task due to its length. One response from OpenAI is limited to 2048 tokens, and a text of 15,000 words is around 75,000-150,000 tokens depending on the complexity and word length. Making an article using multiple prompts also can produce inconsistent results, as the AI doesn’t remember past responses. Thus, it’s best to work with information that can be contained within this limit. Nonetheless, I’d be glad to help with a shorter article or segment of your topic.
