Manage Your API Services with Llama-Nexus

This tutorial shows you how to use Llama-Nexus to manage multiple OpenAI-compatible API services.

Install the Llama-Nexus software​

The following command installs the Linux on x86 version of llama-nexus.

curl -LO https://github.com/LlamaEdge/llama-nexus/releases/download/0.5.0/llama-nexus-unknown-linux-gnu-x86_64.tar.gz

tar xvf llama-nexus-unknown-linux-gnu-x86_64.tar

Download for your platfrom here: https://github.com/LlamaEdge/llama-nexus/releases/tag/0.5.0

Start Llama-Nexus​

./llama-nexus --config config.toml

By default, Llama-Nexus listens on port 3389.

Register a chat service​

Assuming you already have an OpenAI-compatible API server for your LLM, let‘s register it with Llama-Nexus.

If you’d like to run a model locally, refer to the Quick Start with LlamaEdge guide.

Register the LLM chat API server for the /chat/completions endpoint:

curl --location 'http://localhost:3389/admin/servers/register' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer YOUR_API_KEY_GOES_HERE' \
--data '{
    "url": "http://localhost:8080",
    "kind": "chat"
}'

To register multiple services, repeat the request with different URLs.

For other types of models, please check the Register guide

Call the service​

Since Llama-Nexus is OpenAI-compatible, you can use any OpenAI-compatible client or the API spec to call your services:

curl -X POST http://localhost:9095/v1/chat/completions \
  -H 'accept: application/json' \
  -H 'Content-Type: application/json' \
  -d '{"messages":[{"role":"system", "content": "You are a helpful assistant."},{"role":"user", "content": "What is the weather in Singapore?"}]}'
