Prompt

What it means

An instruction, question or information provided to an AI model.

Code example

const res = await openai.chat.completions.create({
  model: "gpt-4o",
  messages: [
    { role: "system", content: "You are a concise assistant." },
    { role: "user", content: "Explain tokens in one line." },
  ],
});

Why it matters

Prompts define the task and provide the immediate input that influences the model's response.
