Prompt Engineering and Scaffolding
Prompt engineering involves restructuring problems into checklists or decision trees to guide the model's response. This helps avoid known limitations and improves the quality of the output. Using scaffolding, such as providing context and structuring prompts, is more valuable than linguistic cleverness.
Understanding LLMs
There are different mental models for understanding how LLMs work. One model views prompts as sculpting the space of possible text, removing dimensions and narrowing down possibilities. Another mental model focuses on RLHF (reinforcement learning from human feedback), where the model predicts text that it believes would meet human approval. Auto-regressive inference, involving the token sampling process and the probability of out-of-distribution tokens, is another important model to consider.
The Use of Case Shot Prompts
Crafting well-designed case shot prompts involves capturing the boundaries of the input distribution, creating prompts with artificial rare classes or specific edge cases. This allows the model to learn how to handle these scenarios and generate appropriate responses. Using structured prompts and context can greatly influence the model's behavior, making it important to have domain expertise and knowledge of what the model can and cannot do well.
Resources for Further Exploration
learnprompting.org is a valuable resource that provides techniques and references on prompt engineering. Additionally, following discussions and papers shared on platforms like Twitter can keep you up-to-date with the latest advancements and insights in the field.
Today we’re joined by Riley Goodside, staff prompt engineer at Scale AI. In our conversation with Riley, we explore LLM capabilities and limitations, prompt engineering, and the mental models required to apply advanced prompting techniques. We dive deep into understanding LLM behavior, discussing the mechanism of autoregressive inference, comparing k-shot and zero-shot prompting, and dissecting the impact of RLHF. We also discuss the idea that prompting is a scaffolding structure that leverages the model context, resulting in achieving the desired model behavior and response rather than focusing solely on writing ability.
