# Open Responses

Base class for interacting with providers that implement the [Open Responses API specification](https://openresponses.org). 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](/reference/models/ollama-responses) for Ollama
* [OpenRouterResponses](/reference/models/openrouter-responses) for OpenRouter

```python theme={null}
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!")
```
