# US-only Serverless

> Run Serverless inference exclusively in the US

US-only Serverless serves inference exclusively from the US, making it a good fit for compliance needs.

## Available models

| Model   | `model` ID                              |
| ------- | --------------------------------------- |
| Kimi K3 | `accounts/fireworks/routers/kimi-k3-us` |

## How to use it

Use a US router from the table above as the `model` ID.

```bash theme={null}
curl https://api.fireworks.ai/inference/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $FIREWORKS_API_KEY" \
  -d '{
    "model": "accounts/fireworks/routers/kimi-k3-us",
    "messages": [{"role": "user", "content": "Hello"}]
  }'
```

```python theme={null}
from fireworks import Fireworks

client = Fireworks()

response = client.chat.completions.create(
    model="accounts/fireworks/routers/kimi-k3-us",
    messages=[{"role": "user", "content": "Hello"}],
)

print(response.choices[0].message.content)
```
