Marimo Integration

Marimo is a modern, reactive Python notebook that supports AI-powered code completion and assistance. It provides an OpenAI-compatible configuration for AI features.

Marimo's AI completion supports custom OpenAI-compatible endpoints.

Prerequisites

An LLM API account with an API key
Marimo installed or accessible

Setup

Get Your LLM API Key

Log in to your LLM API dashboard
Click Create Key to Start
Copy your new API key immediately — it will only be shown once
Store the key securely (e.g., in a password manager or .env file)

LLM API is an OpenAI-compatible gateway that gives you access to dozens of AI models through a single API key and endpoint.

Configure LLM API in Marimo

Set environment variables:

export OPENAI_API_KEY="your-llm-api-key-here"
export OPENAI_BASE_URL="https://api.llmapi.ai/v1"

Or configure in marimo settings:

\# In marimo.toml or settings
[ai]
api_key = "your-llm-api-key-here"
base_url = "https://api.llmapi.ai/v1"
model = "openai/gpt-4o"

Restart Marimo --- AI completion will use LLM API.

Test the Integration

Verify that Marimo can successfully communicate with LLM API by sending a test request. All requests will now be routed through LLM API.

Marimo's reactive notebook + LLM API creates a powerful interactive AI development environment.

Benefits of Using LLM API with Marimo

Multi-Provider Access: Use models from OpenAI, Anthropic, Google, and more through a single API
Cost Control: Track and limit your AI spending with detailed usage analytics
Unified Billing: One account for all providers instead of managing multiple API keys
Caching: Reduce costs with response caching for repeated requests
