## Quick start
### Online serving (OpenAI API-Compatible server)
Deploy an OpenAI API-compatible server using FastDeploy with the following commands:
#### Start service
**Deploy the ERNIE-4.5-300B-A47B-Paddle model with WINT4 precision and 32K context length on 4 XPUs**
```bash
export XPU_VISIBLE_DEVICES="0,1,2,3" # Specify which cards to be used
python -m fastdeploy.entrypoints.openai.api_server \
--model baidu/ERNIE-4.5-300B-A47B-Paddle \
--port 8188 \
--tensor-parallel-size 4 \
--max-model-len 32768 \
--max-num-seqs 64 \
--quantization "wint4" \
--gpu-memory-utilization 0.9
```
**Note:** When deploying on 4 XPUs, only two configurations are supported which constrained by hardware limitations such as interconnect capabilities.
`export XPU_VISIBLE_DEVICES="0,1,2,3"`
or
`export XPU_VISIBLE_DEVICES="4,5,6,7"`
Refer to [Parameters](../../parameters.md) for more options.
All supported models can be found in the *Supported Models* section above.
#### Send requests
Send requests using either curl or Python
```bash
curl -X POST "http://0.0.0.0:8188/v1/chat/completions" \
-H "Content-Type: application/json" \
-d '{
"messages": [
{"role": "user", "content": "Where is the capital of China?"}
]
}'
```
```python
import openai
host = "0.0.0.0"
port = "8188"
client = openai.Client(base_url=f"http://{host}:{port}/v1", api_key="null")
response = client.completions.create(
model="null",
prompt="Where is the capital of China?",
stream=True,
)
for chunk in response:
print(chunk.choices[0].text, end='')
print('\n')
response = client.chat.completions.create(
model="null",
messages=[
{"role": "user", "content": "Where is the capital of China?"},
],
stream=True,
)
for chunk in response:
if chunk.choices[0].delta:
print(chunk.choices[0].delta.content, end='')
print('\n')
```
For detailed OpenAI protocol specifications, see [OpenAI Chat Compeltion API](https://platform.openai.com/docs/api-reference/chat/create). Differences from the standard OpenAI protocol are documented in [OpenAI Protocol-Compatible API Server](../../online_serving/README.md).
