Prompt Improvement FAQ

Common issues: too vague ("write about AI"), no format instruction ("respond in bullet points"), no audience ("for a 5-year-old vs PhD"), no constraint ("under 200 words"), and no role ("you are an expert nutritionist"). The more specific and structured the prompt, the more predictable the output. Think of prompting as writing a very clear work brief.

Longer prompts generally produce better results up to a point, because each constraint or instruction rules out bad outputs. But extremely long prompts can cause models to lose focus on later instructions ("lost in the middle" problem). Ideal prompt: enough context + clear task + output format + 2-3 examples. Typically 100-500 words for complex tasks.

In the API, the system prompt sets the AI's persona, capabilities, and persistent constraints (role, tone, domain). The user prompt contains the specific request for that turn. In ChatGPT, the system prompt is set via "Custom Instructions". In Claude and GPT-4 API, it is the first message with role="system". Good system prompts are reused across many conversations; user prompts are task-specific.
