Cerebras OpenAI - Agno

OpenAI-Compatible Integration

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

Cerebras deprecated llama-4-scout-17b-16e-instruct on 2025-11-03 — see Cerebras’s deprecation notice. 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 explicitly there.

Basic Usage

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

uv pip install openai cerebras-cloud-sdk

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
