Zero-shot prompting means asking the AI to do a task with no examples — relying purely on the model's training.

When It Works

• Common, well-understood tasks (summarize, translate, explain)
• Tasks the model has seen many times in training

How to Maximize Zero-Shot Results

• Be very specific about what you want
• Specify the audience ("explain to a beginner")
• Specify the format ("in 3 bullet points")
• Specify the tone ("professional", "casual", "technical")
