Overview
A response deserialization and extraction pattern that transforms raw API responses into typed data structures for downstream consumption.
Description
Response Processing is the step of extracting useful information from a structured API response object. For chat completion responses, this involves navigating the response hierarchy (response → choices → message → content) to extract the generated text, checking for tool calls, and accessing usage statistics. The response object is a typed Pydantic model that provides attribute access and validation.
Usage
Use this principle after every chat completion or streaming request to extract the generated content and metadata. Always check response.choices[0].finish_reason to determine whether the response completed normally, was truncated, or triggered a tool call.
Theoretical Basis
API responses follow a structured envelope pattern:
- Top level: Contains metadata (id, model, created timestamp)
- Choices array: One or more completion alternatives
- Message: The generated message with role and content
- Usage: Token consumption statistics for billing and monitoring
