Responses

Overview

responses is OpenAI's most advanced model response generation interface, supporting richer interactive capabilities and tool integration.

Core Features

Multimodal Input: Supports text and image inputs

Text Output: Generates high-quality text responses

Stateful Interaction: Uses outputs from previous responses as subsequent inputs, maintaining conversation coherence

Built-in Tools: Integrates file search, web search, computer use, and other functions

Function Calling: Allows models to access external systems and data sources

Important Notes

⚠️ Model Variations
Different model providers may support different request parameters and return varying response fields. We strongly recommend consulting the respective model provider's official documentation for complete parameter lists and usage methods.

⚠️ Response Pass-through Principle
CometAPI typically does not modify model responses beyond reverse-engineered formats, ensuring you receive response content consistent with the original API.
