Frequently Asked Questions
Are these prompts model-specific?
Mostly no. These templates use "Persona patterns" (e.g., "Act as a...") which rely on the fundamental training data of all major LLMs. They will work well on GPT-4, Claude 3, and Llama.
Zero-shot vs Few-shot?
These are primarily "Zero-shot" prompts (instructions without examples). To make them "Few-shot", simply add 2-3 examples of the input/output format you desire at the end of the prompt. Few-shot almost always outperforms Zero-shot.
