What makes a good AI prompt?

Specificity over cleverness. The 4-part formula: (1) role the AI should play, (2) task to perform, (3) context or constraints, (4) output format. Avoid vague instructions like 'write something about X'; demand specific length, structure, audience, and constraints.

Does prompting technique matter less with modern models?

Less than in 2023, but still significant. Claude Opus 4 and GPT-4o handle loose prompts better than earlier models. But clear prompts still produce 2-3x better outputs, especially for structured tasks, code generation, and multi-step reasoning. Investment in prompt quality scales.

What's chain-of-thought prompting?

Asking the model to 'think step by step' or show its reasoning before giving a final answer. Improves accuracy on reasoning tasks 20-40% for older models. Modern reasoning models (o1, DeepSeek R1, Claude Opus 4 with extended thinking) do this natively and often don't need the instruction.

Should I use system vs user prompts?

System prompts set persistent behavior (role, tone, constraints, available tools). User prompts are the specific request. In API use, system goes in the first turn's system field; everything else is user turns. ChatGPT's 'Custom Instructions' maps to system prompts.
