# DeepSeek
Aider can connect to the DeepSeek.com API.
To work with DeepSeek's models, you need to set the `DEEPSEEK_API_KEY` environment variable with your [DeepSeek API key](https://platform.deepseek.com/api_keys).
The DeepSeek Chat V3 model has a top score on aider's code editing benchmark.
First, install aider:
{% include install.md %}
Then configure your API keys:
```
export DEEPSEEK_API_KEY=<key> # Mac/Linux
setx DEEPSEEK_API_KEY <key> # Windows, restart shell after setx
```
Start working with aider and DeepSeek on your codebase:
```bash
# Change directory into your codebase
cd /to/your/project
# Use DeepSeek Chat v3
aider --model deepseek/deepseek-chat
```
