Prompt

A prompt is the complete input passed to a generative AI model, and can combine a system instruction, retrieved context, few-shot examples, and the user’s actual question, all concatenated before the model sees them. In Amazon Bedrock, each call to a foundation model is built around this prompt payload, and the Converse API gives a consistent format for handling multi-turn conversation history alongside it. The exam distinction to know is prompt versus system prompt: the system prompt sets persistent behavior (tone, role, guardrails), while the user prompt carries the per-turn request.
