```yaml

Primary model (Ollama Qwen 2.5 Coder 14B)

model: ollama/qwen2.5-coder:14b

Environment variables for API access

set-env:

- AZURE_API_VERSION=2024-08-01-preview

- AZURE_API_BASE=https://7seda-m5zngwf8-eastus2.cognitiveservices.azure.com

# - AZURE_API_KEY= # Set via environment variable

# - DEEPSEEK_API_KEY= # Set via environment variable

# - CODESTRAL_API_KEY= # Set via environment variable

2. **Explain API key setup**: Inform the user that sensitive API keys should be set as environment variables (not in the config file):

```bash

export AZURE_API_KEY="your-azure-key"

export DEEPSEEK_API_KEY="your-deepseek-key"

export CODESTRAL_API_KEY="your-codestral-key"

```

3. **Create instructions file** (optional): If `~/.notes/aider_default_instructions.md` doesn't exist, ask if they want to create it with default coding standards.

4. **Verify Ollama setup** (if using local models): Confirm Ollama is running with `ollama list` and the `qwen2.5-coder:14b` model is available. If not: `ollama pull qwen2.5-coder:14b`
