LLM models, like OpenAI's ChatGPT, rely heavily on well-written prompts for accurate responses.Crafting effective prompts involves iterating, evaluating, and templatizing queries.Quality prompts lead to better AI model output, saving time and improving results.Iteration is key: start simple, test the output, refine, and iterate further for specificity.By refining prompts iteratively, you can achieve accurate and relevant responses.A prompt template example for generating SQL queries is provided, emphasizing metadata and user instructions.An example prompt involving generating a BigQuery SQL query based on metadata and user requirements is demonstrated.The sample prompt leads to the generation of a specific SQL query for calculating total deposits of yesterday.Submitting the prompt to LLM resulted in a BigQuery SQL query for total deposits of yesterday.Crafting precise prompts is essential for AI models to provide contextually appropriate responses.
