# Cerebras OpenAI

> Use Cerebras with Agno through an OpenAI-compatible interface.

## OpenAI-Compatible Integration

Cerebras also exposes an OpenAI-compatible interface, so you can use it with tools and libraries built for the OpenAI API.

> [!WARNING]
>
> Agno v2.7.2 defaults `CerebrasOpenAI.id` to the retired `llama-4-scout-17b-16e-instruct` model. Set `id="gpt-oss-120b"` or another current [Cerebras model](https://inference-docs.cerebras.ai/models/overview) explicitly.

### Basic Usage

The `CerebrasOpenAI` class provides an OpenAI-style interface for Cerebras models. First, install the required packages:

```shell theme={null}
uv pip install openai cerebras-cloud-sdk
```

```python theme={null}
from agno.agent import Agent
from agno.models.cerebras import CerebrasOpenAI

agent = Agent(
    model=CerebrasOpenAI(
        id="gpt-oss-120b",  # Model ID to use
        # base_url="https://api.cerebras.ai/v1", # Optional: default endpoint for Cerebras
    ),
    markdown=True,
)

# Print the response in the terminal
agent.print_response("write a two sentence horror story")
```

### Configuration Options

The `CerebrasOpenAI` class accepts the following parameters:

| Parameter | Type | Description | Default |
| - | - | - | - |
| `id` | str | Model identifier (for example, "gpt-oss-120b") | "llama-4-scout-17b-16e-instruct" |
| `name` | str | Display name for the model | "CerebrasOpenAI" |
| `provider` | str | Provider name | "CerebrasOpenAI" |
| `api_key` | str | API key (falls back to CEREBRAS\_API\_KEY environment variable) | None |
| `base_url` | str | URL of the Cerebras OpenAI-compatible endpoint | "[https://api.cerebras.ai/v1](https://api.cerebras.ai/v1)" |
| `parallel_tool_calls` | Optional\[bool] | Whether to run tool calls in parallel (set to False automatically for llama-4-scout-17b-16e-instruct) | None |

`CerebrasOpenAI` also supports the parameters of [OpenAI](https://agno-v2.mintlify.site/reference/models/openai.md).
