The Art and Science of Few-Shot-Prompting with ChatGPT

Thursday, July 06, 2023

Unleashing the full potential of AI involves understanding how to effectively interact with them. Large Language Models (LLMs), such as GPT-3, can execute tasks without prior examples - a capability known as "zero-shot" prompting.

Here's an everyday example that demonstrates this capability:

Pro Example: Imagine you need to analyze customer sentiment about your latest product. You could ask the model to "Classify the text into neutral, negative, or positive" for a customer review, such as, "This product makes my life easier." ChatGPT would correctly classify this sentiment as "Positive." This demonstrates its ability to understand and process instructions without prior examples, illustrating zero-shot capabilities in action.

However, there can be situations where zero-shot doesn't quite hit the mark.

Con Example: Let's say you ask the model to summarize a highly technical document or predict future trends based on complex data. Here, zero-shot might fall short due to the complexity and specificity required for the task.

The good news? There are solutions, like few-shot prompting, where you provide the model with a few examples to guide its output. Moreover, advancements like Instruction Tuning and Reinforcement Learning from Human Feedback (RLHF) are being used to make these models even more aligned with human preferences.
