# Supported Models

FastDeploy currently supports the following models, which can be downloaded automatically during FastDeploy deployment.Specify the ``model`` parameter as the model name in the table below to automatically download model weights (all supports resumable downloads). The following three download sources are supported:

- [AIStudio](https://aistudio.baidu.com/modelsoverview)
- [ModelScope](https://www.modelscope.cn/models)
- [HuggingFace](https://huggingface.co/models)

When using automatic download, the default download source is AIStudio. Users can modify the default download source by setting the ``FD_MODEL_SOURCE`` environment variable, which can be set to “AISTUDIO”, ‘MODELSCOPE’ or “HUGGINGFACE”. The default download path is ``~/`` (i.e., the user's home directory). Users can modify the default download path by setting the ``FD_MODEL_CACHE`` environment variable, e.g.:

```bash
export FD_MODEL_SOURCE=AISTUDIO # "AISTUDIO", "MODELSCOPE" or "HUGGINGFACE"
export FD_MODEL_CACHE=/ssd1/download_models
```

> ⭐ **Note**: Models marked with an asterisk can directly use **HuggingFace Torch weights** and support **FP8/WINT8/WINT4** as well as **BF16**. When running inference, you need to enable **`--load_choices "default_v1"`**.

> Example launch Command using baidu/ERNIE-4.5-21B-A3B-PT:
```
python -m fastdeploy.entrypoints.openai.api_server \
       --model baidu/ERNIE-4.5-0.3B-PT \
       --port 8180 \
       --metrics-port 8181 \
       --engine-worker-queue-port 8182 \
       --max-model-len 32768 \
       --max-num-seqs 32 \
       --load_choices "default_v1"
```
