Cerebras Setup Guide

This guide will help you set up Janito to use Cerebras as an LLM provider.

Prerequisites

1. A Cerebras account
2. An API key from Cerebras

Getting an API Key

1. Visit the Cerebras API Keys page
2. Log in to your account
3. Generate a new API key
4. Copy the API key for use in Janito

Configuration

To configure Janito to use Cerebras, you need to set your API key:

janito --set-api-key YOUR_CEREBRAS_API_KEY -p cerebras

Replace YOUR_CEREBRAS_API_KEY with the API key you obtained from Cerebras.

Usage

After setting up your API key, you can use Cerebras models with Janito:

janito -p cerebras "Hello, how are you?"

By default, Janito will use the qwen-3-coder-480b model. You can specify a different model if needed:

janito -p cerebras -m qwen-3-coder-480b "Explain quantum computing"
