# Aider with zurelay

> AI pair programming in your terminal.

Source: https://zurelay.com/docs/integrations/aider

The examples use `claude-opus-5-5`. Any model ID from [the models page](https://zurelay.com/docs/models) works.

## Set it up

1. Point Aider’s OpenAI settings at zurelay with `OPENAI_API_BASE` and `OPENAI_API_KEY`.
2. Prefix model IDs with `openai/` so Aider sends them to that endpoint.
3. To keep the setup, put the same settings in `.aider.conf.yml` in your home directory or repo.

## Configuration

**Shell** (`terminal`):

```bash
export OPENAI_API_BASE="https://api.zurelay.com/v1"
export OPENAI_API_KEY="$ZURELAY_API_KEY"

aider --model openai/claude-opus-5-5 --weak-model openai/deepseek-v4.1-flash
```

**.aider.conf.yml** (`~/.aider.conf.yml`):

```yaml
model: "openai/claude-opus-5-5"
weak-model: "openai/deepseek-v4.1-flash"
openai-api-base: https://api.zurelay.com/v1
openai-api-key: <ZURELAY_API_KEY>
```

> **Note:** Aider may warn that it doesn’t know a model’s context size. It still works; add the model to `.aider.model.metadata.json` to silence the warning.
