DEFINITION
Retrieval-and-Assembly
Retrieval-and-Assembly Task Pattern
Definition
A task pattern where an AI model retrieves relevant information from external sources and assembles it into structured output, rather than reasoning or generating novel content. Tool calling is fundamentally a retrieval-and-assembly task: match query to tool name, extract argument values, emit JSON. This insight enables efficient small models (26M parameters) to outperform larger models on this specific task.
Examples in the Wild
- Example 1:Tool calling: retrieve matching tool from schema, assemble arguments into JSON
- Example 2:RAG: retrieve relevant documents, assemble into answer
- Example 3:Structured extraction: retrieve relevant fields, assemble into structured format
