To access private or gated repositories, you must use a token. By default, the token saved locally (using `huggingface-cli login`) will be used. If you want to authenticate explicitly, use the `--token` option:  
```bash
>>> huggingface-cli download gpt2 config.json --token=hf_****
/home/wauplin/.cache/huggingface/hub/models--gpt2/snapshots/11c5a3d5811f50298f278a704980280950aedb10/config.json
```
