Aider Setup Guide

Overview

Aider is LiteLLM-backed, so any OpenAI-compatible base URL works. Set two env vars and pass openai/MODEL_ID as the model.

Quick Config

Drop these values into the client. Your key auto-fills when you are signed in.

Base URL: https://api.unorouter.ai/v1
API Key: YOUR_API_KEY

Compatibility

Step-by-step setup

1. 1
   Set environment variables

   Aider reads OPENAI_API_BASE and OPENAI_API_KEY from your shell.

   bash

   export OPENAI_API_BASE=https://api.unorouter.ai/v1
   export OPENAI_API_KEY=YOUR_API_KEY

   Sign in to auto-fill your API key

2. 2
   Run aider with the openai/ prefix

   LiteLLM uses the openai/ prefix to route the request through its OpenAI driver. Append your UnoRouter model id.

   bash

   aider --model openai/YOUR_MODEL_ID

3. 3
   Optional: persist in .aider.conf.yml

   Drop a config in your project root so you do not have to repeat the flags.

   yaml

   openai-api-base: https://api.unorouter.ai/v1
   openai-api-key: YOUR_API_KEY
   model: openai/YOUR_MODEL_ID

   Sign in to auto-fill your API key

Recommended models

Free models that work well here. Paste any model id into the client.

Gotchas

• !Always include /v1 in the base URL.
• !LiteLLM may print unknown model warnings. Use --no-show-model-warnings or supply a context window via --model-metadata-file if it gets noisy.
