This chapter introduces the concept of metaprompting. In this approach, the LLM is not used directly to answer a given question; instead, the system is first employed to generate an appropriate prompt for creating the subsequent solution. Prompts can be generated either for the LLM itself or for third-party systems. For example, ChatGPT can generate prompts for creating images using Midjourney. Additionally, metaprompting can be used to further optimize existing prompts. Finally, the Valisory Prompt Studio is presented as a complex, fully automated prompt that integrates all previously described concepts into a comprehensive workflow.
