What is OpenModelZ?

OpenModelZ ( mdz ) is tool to deploy your models to any cluster (GCP, AWS, Lambda labs, your home lab, or even a single machine).

Getting models into production is hard for data scientists and SREs. You need to configure the monitoring, logging, and scaling infrastructure, with the right security and permissions. And then setup the domain, SSL, and load balancer. This can take weeks or months of work even for a single model deployment.

You can now use mdz deploy to effortlessly deploy your models. OpenModelZ handles all the infrastructure setup for you. Each deployment gets a public subdomain, like http://jupyter-9pnxd.2.242.22.143.modelz.live, making it easily accessible.

OpenModelZ

Benefits

OpenModelZ provides the following features out-of-the-box:

OpenModelZ is the foundational component of the ModelZ platform available at modelz.ai.

How it works

Get a server (could be a cloud VM, a home lab, or even a single machine) and run the mdz server start command. OpenModelZ will bootstrap the server for you.

$ mdz server start
🚧 Creating the server...
🚧 Initializing the load balancer...
🚧 Initializing the GPU resource...
🚧 Initializing the server...
🚧 Waiting for the server to be ready...
🐋 Checking if the server is running...
🐳 The server is running at http://146.235.213.84.modelz.live
🎉 You could set the environment variable to get started!

export MDZ_URL=http://146.235.213.84.modelz.live
$ export MDZ_URL=http://146.235.213.84.modelz.live

Then you could deploy your model with a single command mdz deploy and get the endpoint:

$ mdz deploy --image modelzai/gradio-stable-diffusion:23.03 --name sdw --port 7860 --gpu 1
Inference sd is created
$ mdz list
 NAME  ENDPOINT                                                 STATUS  INVOCATIONS  REPLICAS 
 sdw   http://sdw-qh2n0y28ybqc36oc.146.235.213.84.modelz.live   Ready           174  1/1      
       http://146.235.213.84.modelz.live/inference/sdw.default

Quick Start 🚀

Install mdz

You can install OpenModelZ using the following command:

pip install openmodelz

You could verify the installation by running the following command:

mdz

Once you've installed the mdz you can start deploying models and experimenting with them.

Bootstrap mdz

It's super easy to bootstrap the mdz server. You just need to find a server (could be a cloud VM, a home lab, or even a single machine) and run the mdz server start command.

Notice: We may require the root permission to bootstrap the mdz server on port 80.

🎉 You could set the environment variable to get started!

export MDZ_URL=http://192.168.71.93.modelz.live

The internal IP address will be used as the default endpoint of your deployments. You could provide the public IP address of your server to the mdz server start command to make it accessible from the outside world.

# Provide the public IP as an argument
$ mdz server start 1.2.3.4

You could also specify the registry mirror to speed up the image pulling process. Here is an example:

$ mdz server start --mirror-endpoints https://docker.mirrors.sjtug.sjtu.edu.cn

Create your first UI-based deployment

Once you've bootstrapped the mdz server, you can start deploying your first applications. We will use jupyter notebook as an example in this tutorial. You could use any docker image as your deployment.

$ mdz deploy --image jupyter/minimal-notebook:lab-4.0.3 --name jupyter --port 8888 --command "jupyter notebook --ip='*' --NotebookApp.token='' --NotebookApp.password=''"
Inference jupyter is created
$ mdz list
 NAME     ENDPOINT                                                   STATUS  INVOCATIONS  REPLICAS
 jupyter  http://jupyter-9pnxdkeb6jsfqkmq.192.168.71.93.modelz.live  Ready           488  1/1
          http://192.168.71.93/inference/jupyter.default

You could access the deployment by visiting the endpoint URL. The endpoint will be automatically generated for each deployment with the following format: <name>-<random-string>.<ip>.modelz.live.

It is http://jupyter-9pnxdkeb6jsfqkmq.192.168.71.93.modelz.live in this case. The endpoint could be accessed from the outside world as well if you've provided the public IP address of your server to the mdz server start command.

jupyter notebook

Create your first OpenAI compatible API server

You could also create API-based deployments. We will use OpenAI compatible API server with Bloomz 560M as an example in this tutorial.

$ mdz deploy --image modelzai/llm-bloomz-560m:23.07.4 --name simple-server
Inference simple-server is created
$ mdz list
 NAME           ENDPOINT                                                         STATUS  INVOCATIONS  REPLICAS 
 jupyter        http://jupyter-9pnxdkeb6jsfqkmq.192.168.71.93.modelz.live        Ready           488  1/1      
                http://192.168.71.93/inference/jupyter.default                                                 
 simple-server  http://simple-server-lagn8m9m8648q6kx.192.168.71.93.modelz.live  Ready             0  1/1      
                http://192.168.71.93/inference/simple-server.default

You could use OpenAI python package and the endpoint http://simple-server-lagn8m9m8648q6kx.192.168.71.93.modelz.live in this case, to interact with the deployment.

import openai
openai.api_base="http://simple-server-lagn8m9m8648q6kx.192.168.71.93.modelz.live"
openai.api_key="any"

# create a chat completion
chat_completion = openai.ChatCompletion.create(model="bloomz", messages=[
    {"role": "user", "content": "Who are you?"},
    {"role": "assistant", "content": "I am a student"},
    {"role": "user", "content": "What do you learn?"},
], max_tokens=100)

Scale your deployment

You could scale your deployment by using the mdz scale command.

$ mdz scale simple-server --replicas 3

The requests will be load balanced between the replicas of your deployment.

You could also tell the mdz to autoscale your deployment based on the inflight requests. Please check out the Autoscaling documentation for more details.

Debug your deployment

Sometimes you may want to debug your deployment. You could use the mdz logs command to get the logs of your deployment.

$ mdz logs simple-server
simple-server-6756dd67ff-4bf4g: 10.42.0.1 - - [27/Jul/2023 02:32:16] "GET / HTTP/1.1" 200 -
simple-server-6756dd67ff-4bf4g: 10.42.0.1 - - [27/Jul/2023 02:32:16] "GET / HTTP/1.1" 200 -
simple-server-6756dd67ff-4bf4g: 10.42.0.1 - - [27/Jul/2023 02:32:17] "GET / HTTP/1.1" 200 -

You could also use the mdz exec command to execute a command in the container of your deployment. You do not need to ssh into the server to do that.

$ mdz exec simple-server ps
PID   USER     TIME   COMMAND
    1 root       0:00 /usr/bin/dumb-init /bin/sh -c python3 -m http.server 80
    7 root       0:00 /bin/sh -c python3 -m http.server 80
    8 root       0:00 python3 -m http.server 80
    9 root       0:00 ps
$ mdz exec simple-server -ti bash
bash-4.4#

Or you could port-forward the deployment to your local machine and debug it locally.

$ mdz port-forward simple-server 7860
Forwarding inference simple-server to local port 7860

Add more servers

You could add more servers to your cluster by using the mdz server join command. The mdz server will be bootstrapped on the server and join the cluster automatically.

$ mdz server join <internal ip address of the previous server>
$ mdz server list
 NAME   PHASE  ALLOCATABLE      CAPACITY        
 node1  Ready  cpu: 16          cpu: 16         
               mem: 32784748Ki  mem: 32784748Ki 
               gpu: 1           gpu: 1      
 node2  Ready  cpu: 16          cpu: 16         
               mem: 32784748Ki  mem: 32784748Ki 
               gpu: 1           gpu: 1

Label your servers

You could label your servers to deploy your models to specific servers. For example, you could label your servers with gpu=true and deploy your models to servers with GPUs.

$ mdz server label node3 gpu=true type=nvidia-a100
$ mdz deploy ... --node-labels gpu=true,type=nvidia-a100

Architecture

OpenModelZ is inspired by the k3s and OpenFaaS, but designed specifically for machine learning deployment. We keep the core of the system simple, and easy to extend.

You do not need to read this section if you just want to deploy your models. But if you want to understand how OpenModelZ works, this section is for you.

OpenModelZ

OpenModelZ is composed of two components:

A request will be routed to the inference servers by the load balancer. And the autoscaler will scale the number of inference servers based on the workload. We provide a domain *.modelz.live by default, with the help of a wildcard DNS server to support the public accessible subdomain for each deployment. You could also use your own domain.

You could check out the architecture documentation for more details.
