Introduction to Prompt Engineering [0:00]
The presenter introduces the concept of smart prompting and its role in generating smart outputs, aiming to provide practical tips and techniques applicable to prompt creation. She works at autogen, where they assist organizations in crafting winning bids and proposals using large language models and linguistic engineering. She addresses the common questions about prompt engineering and clarifies her role in the field.
Prompt Crafting vs. Prompt Engineering [0:30]
The discussion differentiates between prompt crafting and prompt engineering. Prompt crafting involves real-time interaction with a model, providing a prompt for a specific instance. While it can yield useful responses, the prompt's effectiveness isn't guaranteed across different texts or contexts. Prompt engineering, on the other hand, focuses on curating prompts that produce replicable and reliable outputs for a specific function. It involves continuous measurement and improvement, establishing frameworks that can scale effectively with any input.
Prompting Techniques: Zero-Shot, Multi-Shot, and Chain of Thought [1:18]
The presenter introduces several popular prompting techniques, including zero-shot, multi-shot, and chain-of-thought prompting. These techniques are demonstrated through the task of extracting and classifying data using the autogen platform. Zero-shot prompting, which involves providing an instruction without examples, is a common starting point but may lack nuanced understanding. Multi-shot prompting offers examples to provide more context, while chain-of-thought prompting asks the model to explain its reasoning step by step.
Demonstrating Prompting Techniques with Examples [2:05]
The presenter demonstrates the prompting techniques with a classification task. In the zero-shot example, the model fails to capture the nuanced sentiment of a statement. Multi-shot prompting, by providing examples of positive, negative, and neutral statements, yields more accurate and nuanced outputs. However, it's important to be aware of potential biases in multi-shot prompting, ensuring that examples cover a wide range of interpretations. Chain of thought prompting aids in model debugging by revealing the model's thought process.
Prompt Chaining for Complex Tasks [4:32]
Prompt chaining, or multi-step prompting, is introduced as a method for handling complex reasoning tasks that cannot be instructed in one go. This technique involves breaking down a complex task into several steps to ensure the best piece of text is worked on at each stage, reducing model inconsistency and preventing conflicting instructions from interfering with each other. For example, analyzing sentiment on a large body of text can be broken down into classifying statements, extracting themes, and grouping those themes.
Practical Application of Prompt Chaining [5:11]
The presenter shows the output of the first prompt, which classifies customer feedback into sentiments using a multi-shot prompt on a larger dataset. The second prompt, a zero-shot prompt, identifies all the themes in the customer feedback, emphasizing the importance of repetition and providing context to the model. The third prompt classifies the themes into positive, negative, neutral, or other categories, providing a justification for each theme's sentiment. This multi-step approach yields more nuanced, accurate, and useful results than using a single technique.
Conclusion and Additional Applications [7:28]
The presenter concludes that simplicity is key, and while single-shot prompts may not always be nuanced enough, they are often the best choice. Once a satisfactory output is achieved, the possibilities are endless, including translating the output into JSON, adjusting the tone, or converting it into a PowerPoint presentation. Effective prompts should be direct, unambiguous, and relevant, with the techniques discussed serving to ensure these requirements are met.
Q&A: Refining Prompts [8:48]
In a Q&A segment, the presenter addresses how to refine prompts, noting that models can be prompted to refine prompts. While models can provide a good initial framework, it's important to consider the specific use case, target audience, and subjective opinion when writing prompts. Other models can be used to generate a first draft of a good prompt to improve one's own prompts.
