Prompt
The textual instruction or context given to an AI model to guide output style, scope, and task.
A prompt is the input instruction (or instruction set) sent to an AI system to steer what it should do and how it should respond. In natural language processing (NLP) and chatbots, the prompt is usually the user message plus system context.
Good prompts typically define task, constraints, and desired output format. Prompt quality directly affects usefulness, consistency, and error rate. Adversarial misuse: jailbreaks or prompt injection, is a separate concern from helpful task design; mitigations include guardrails and red teaming.
