Open Responses

Base class for interacting with providers that implement the Open Responses API specification. This provides a foundation for multi-provider, interoperable LLM interfaces based on the OpenAI Responses API.

Providers that implement this spec include Ollama (v0.13.3+) and OpenRouter.

Key Differences from OpenAI Responses

• Configurable base_url for pointing to different API endpoints
• Stateless by default (no previous_response_id chaining)
• Flexible api_key handling for providers that don’t require authentication

Parameters

Parameter	Type	Default	Description
id	str	"not-provided"	The ID of the model to use
name	str	"OpenResponses"	The name of the model
provider	str	"OpenResponses"	The provider of the model
api_key	Optional[str]	"not-provided"	The API key for authentication
store	Optional[bool]	False	Whether to store responses (disabled by default for compatible providers)

Usage

For most use cases, prefer the provider-specific classes:

• OllamaResponses for Ollama
• OpenRouterResponses for OpenRouter

from agno.agent import Agent
from agno.models.openai import OpenResponses

agent = Agent(
    model=OpenResponses(
        id="your-model-id",
        base_url="https://your-provider.com/v1",
        api_key="your-api-key",
    ),
)

agent.print_response("Hello!")
