Prompt chaining links multiple prompts together, using the output of one as the input to the next. This guides a model through multi-step reasoning or complex tasks by breaking them into manageable sequential steps.
A research workflow that first prompts the model to identify key questions, then gathers information for each question, then synthesizes a final answer — is using prompt chaining to produce a more reliable and thorough output than a single prompt could achieve. Each step is simpler and more reliable; the chain handles the complexity.
