# 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>
  Cerebras deprecated `llama-4-scout-17b-16e-instruct` on 2025-11-03 — see [Cerebras's deprecation notice](https://inference-docs.cerebras.ai/support/deprecation). Agno v3.0 defaults `CerebrasOpenAI.id` to `gpt-oss-120b`; earlier Agno versions default to the deprecated model, so set `id="gpt-oss-120b"` or another current [Cerebras model](https://inference-docs.cerebras.ai/models/overview) explicitly there.
</Warning>

### 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:
