# LLM Routing
|
|
This demo shows how you can use Plano 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 Plano
|
|
```sh
|
|
sh run_demo.sh
|
|
```
|
|
1. Test with curl (see example below)
|
|
|
|
To also start the AnythingLLM chat UI and Jaeger tracing, pass `--with-ui`:
|
|
```sh
|
|
sh run_demo.sh --with-ui
|
|
```
|
|
|
|
Then navigate to http://localhost:3001/ for AnythingLLM.
|
|
|
|
Following screen shows an example of interaction with Plano 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: mistral/ministral-3b' \
|
|
--data '{"messages": [{"role": "user","content": "hello"}], "model": "gpt-4o"}' \
|
|
http://localhost:12000/v1/chat/completions 2> /dev/null | jq .
|
|
{
|
|
"id": "xxx",
|
|
"object": "chat.completion",
|
|
"created": 1737760394,
|
|
"model": "ministral-3b-latest",
|
|
"choices": [
|
|
{
|
|
"index": 0,
|
|
"messages": {
|
|
"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
|
|
For tracing, start with `--with-ui` and head over to http://localhost:16686/ to view recent traces.
