# LLM Routing
|
|
This demo shows how you can arch gateway to manage keys and route to upstream LLM.
|
|
|
|
# Starting the demo
|
|
1. Please make sure the [pre-requisites](https://github.com/katanemo/arch/?tab=readme-ov-file#prerequisites) are installed correctly
|
|
1. Start Arch
|
|
```sh
|
|
sh run_demo.sh
|
|
```
|
|
1. Navigate to http://localhost:18080/
|
|
|
|
Following screen shows an example of interaction with arch gateway showing dynamic routing. You can select between different LLMs using "override model" option in the chat UI.
|
|
|
|
|
|
|
|
You can also pass in a header to override model when sending prompt. Following example shows how you can use `x-arch-llm-provider-hint` header to override model selection,
|
|
|
|
```bash
|
|
|
|
$ curl --header 'Content-Type: application/json' \
|
|
--header 'x-arch-llm-provider-hint: ministral-3b' \
|
|
--data '{"messages": [{"role": "user","content": "hello"}]}' \
|
|
http://localhost:12000/v1/chat/completions 2> /dev/null | jq .
|
|
{
|
|
"id": "xxx",
|
|
"object": "chat.completion",
|
|
"created": 1737760394,
|
|
"model": "ministral-3b-latest",
|
|
"choices": [
|
|
{
|
|
"index": 0,
|
|
"message": {
|
|
"role": "assistant",
|
|
"tool_calls": null,
|
|
"content": "Hello! How can I assist you today? Let's chat about anything you'd like. 😊"
|
|
},
|
|
"finish_reason": "stop"
|
|
}
|
|
],
|
|
"usage": {
|
|
"prompt_tokens": 4,
|
|
"total_tokens": 25,
|
|
"completion_tokens": 21
|
|
}
|
|
}
|
|
|
|
```

# Observability
|
|
Arch gateway publishes stats endpoint at http://localhost:19901/stats. In this demo we are using prometheus to pull stats from arch and we are using grafana to visualize the stats in dashboard. To see grafana dashboard follow instructions below,
|
|
|
|
1. Navigate to http://localhost:3000/ to open grafana UI (use admin/grafana as credentials)
|
|
1. From grafana left nav click on dashboards and select "Intelligent Gateway Overview" to view arch gateway stats
|
|
1. For tracing you can head over to http://localhost:16686/ to view recent traces.
|
|
|
|
Following is a screenshot of tracing UI showing call received by arch gateway and making upstream call to LLM,
