Deploy a Pro AI Server with Hugging Face TGI

Your AI Intern Can’t Multitask

You’re a hero. You followed the previous lessons and built an amazing automation using a local LLM with Ollama. It summarizes sales calls, drafts follow-up emails, and updates the CRM. You show it to your sales team, and they love it. They all want to use it. Right now.

So, you give them the script. The first salesperson runs it. It works beautifully. Then the second salesperson runs it. The first person’s script slows to a crawl. The third person runs it, and your computer’s fan starts screaming like it’s trying to achieve liftoff. The whole system grinds to a halt. Every request is now stuck in a massive traffic jam, waiting for its turn to use the single-lane road that is your Ollama instance.

You’ve just discovered the difference between a personal hobby project and a real business service. Your brilliant AI intern can only talk to one person at a time. To serve a whole team, you don’t need an intern; you need to build a call center.

Why This Matters

This is the moment you graduate from building personal automations to creating scalable, internal AI services. The workflow we’re building today solves the critical problems that stop AI projects from being used across a business:

Blistering Speed. We’re moving from a general-purpose tool to a highly specialized, optimized server built by the experts at Hugging Face. On a GPU, the performance increase isn’t just noticeable; it’s night and day. This is the difference between a 10-second response and a 1-second response.
True Concurrency. This server is designed from the ground up to handle many requests at once. It’s like upgrading from a single-lane country road to an 8-lane superhighway. Your entire team can hit it simultaneously, and it won’t break a sweat.
Production-Ready Stability. This isn’t an experimental tool. Text Generation Inference (TGI) is the same software Hugging Face uses to power its own massive inference platform. It’s robust, reliable, and ready for serious work.

This workflow replaces the single-user, desktop-grade Ollama with an enterprise-grade, multi-user AI serving engine. You’re building the private AI cloud for your company.

What This Tool / Workflow Actually Is

We are using **Text Generation Inference (TGI)**, a free, open-source tool from Hugging Face.

Think of it this way: Ollama is like a powerful gaming PC. It’s easy to use, great for one person, and can run lots of different things. TGI is like a dedicated server blade in a Google data center. It has one hyper-specific job—serving LLMs at maximum speed—and it does that one job better than almost anything else on the planet.

We will run TGI using **Docker**. Docker is a tool that lets us run software in isolated packages called “containers.” It’s like getting a pre-configured, perfectly installed application in a box. We don’t have to worry about dependencies or complex setup; we just tell Docker to run the TGI box, and it handles everything.

What it does:
– Serves open-source LLMs from Hugging Face.
– Optimizes inference for crazy speed, especially on NVIDIA GPUs.
– Handles many simultaneous user requests through clever techniques like continuous batching.
– Provides an API that is (mostly) compatible with OpenAI’s standard.

What it does NOT do:
– It does not have a friendly user interface like Ollama. It’s a professional, command-line tool.
– It does not manage your models for you. You tell it which model to serve when you start it.

Prerequisites

This is a step up in technical skill, but it’s 100% achievable. You are building professional infrastructure now.

Docker Desktop Installed. This is non-negotiable. Go to the official Docker website and install it. It’s a standard installer. This is the magic box that will run our server.
An NVIDIA GPU with at least 12GB of VRAM. Let’s be honest. The main reason to use TGI is for GPU-accelerated speed. You *can* run it on a CPU, but it defeats the purpose. If you don’t have a GPU, you can rent one cheaply from services like Runpod or Vast.ai.
NVIDIA Drivers. Your GPU needs its standard drivers installed on your host machine.
A Hugging Face Account. We need an account to get an API token, which is required to download many models like Llama 3. It’s free.

Don’t be intimidated. You won’t be doing any complex configuration. You’ll be pasting one command.

Step-by-Step Tutorial

Let’s deploy a blazing fast Llama 3 server.

Step 1: Get Your Hugging Face Token

Log into your Hugging Face account, go to your Settings, then “Access Tokens.” Create a new token with “read” permissions. Copy it. You’ll need it in a second.

Step 2: The Magic Docker Command

Open your terminal or PowerShell. This single command will download and start the TGI server. It looks scary, but it’s just telling Docker how to set up the container.

Replace meta-llama/Llama-3-8B-Instruct with any model you want from the Hub, and replace YOUR_HF_TOKEN with the token you just copied.

docker run -d --gpus all -p 8080:80 \\ 
  -v ~/.cache/huggingface:/data \\ 
  --env HUGGING_FACE_HUB_TOKEN=YOUR_HF_TOKEN \\ 
  ghcr.io/huggingface/text-generation-inference:latest \\ 
  --model-id meta-llama/Llama-3-8B-Instruct

Let’s break that down so you know what you’re commanding your robot to do:

docker run -d: Run a container in detached (background) mode.
--gpus all: Give the container access to all your powerful GPUs.
-p 8080:80: Map port 8080 on your computer to port 80 inside the container. This is how we’ll talk to it.
-v ~/.cache/huggingface:/data: This is a smart trick. It maps a folder on your computer to a folder inside the container. This way, when TGI downloads the giant model file, it saves it on your machine. The next time you start the container, it won’t have to download it again.
--env HUGGING_FACE_HUB_TOKEN=...: This securely passes your API token to the container.
ghcr.io/...: This is the official TGI software image.
--model-id ...: This tells TGI which model to download and serve.

When you run this, Docker will start pulling the image and the model. This can take a while the first time. You can watch its progress by running docker logs -f <container_id> (get the ID from docker ps).

Step 3: Verify the Server is Running

Once it’s ready, you can send a test request using `curl` in your terminal.

curl http://127.0.0.1:8080/generate \\ 
    -X POST \\ 
    -d '{"inputs":"What is the capital of France?","parameters":{"max_new_tokens":20}}' \\ 
    -H 'Content-Type: application/json'

If you get a JSON response back with something like `{“generated_text”:”\
\
The capital of France is Paris”}`, you’ve done it. You are now running a production-grade AI server.

Complete Automation Example

The best part about TGI is that it can expose an OpenAI-compatible endpoint. This makes it a drop-in replacement for Ollama or even OpenAI’s own API. Let’s start the server with that compatibility mode enabled.

First, stop the old container with docker stop <container_id>.

Now, run this new command. We’re just adding one flag: --openai-port 8000.

docker run -d --gpus all -p 8080:80 -p 8000:8000 \\ 
  -v ~/.cache/huggingface:/data \\ 
  --env HUGGING_FACE_HUB_TOKEN=YOUR_HF_TOKEN \\ 
  ghcr.io/huggingface/text-generation-inference:latest \\ 
  --model-id meta-llama/Llama-3-8B-Instruct \\ 
  --openai-port 8000

Now, take the exact same Python script we used in the Ollama lesson and just change the port number. Create a file test_tgi.py:

from openai import OpenAI

# Point to our TGI server's OpenAI-compatible endpoint
client = OpenAI(
    base_url='http://localhost:8000/v1',
    api_key='tgi', # can be anything
)

response = client.chat.completions.create(
    model='meta-llama/Llama-3-8B-Instruct', # Model name is ignored by TGI but required by the library
    messages=[
        {"role": "user", "content": "Summarize the following text in one sentence: 'The team held a three-hour meeting to discuss the new project. They analyzed the requirements, assigned tasks, and set a deadline. Everyone left feeling optimistic.'"}
    ]
)

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

Run it with python test_tgi.py. You’ll get a perfect summary, served instantly from your new supercharged server. You just upgraded your entire automation’s engine without changing any of the code.

Real Business Use Cases

TGI’s speed and concurrency unlock automations that were previously impossible or too expensive.

Real-time Sales Call Assistant: An app that transcribes a sales call as it happens and uses TGI to provide the salesperson with real-time talking points and objection-handling suggestions. The low latency is critical.
Internal Company-Wide Search Engine (RAG): Build a RAG system over your company’s documents and host it on TGI. Now, all 200 employees can query it at the same time without slowdowns, creating a true private ChatGPT for your business.
Customer-Facing AI Feature: A SaaS application that offers an “AI-powered report generation” feature. The backend calls the company’s private TGI cluster, ensuring customer data stays private and costs are fixed, no matter how many users use the feature.
High-Throughput Document Processing: An insurance company needs to process 10,000 claims documents per day, extracting structured data. TGI’s ability to handle concurrent requests allows them to build a parallel pipeline that finishes the job in hours, not days.
Developer’s Shared AI Sandbox: Provide your entire development team with a single, powerful TGI endpoint for their experiments. This is cheaper and faster than giving everyone individual OpenAI accounts and allows you to control which models they use.

Common Mistakes & Gotchas

Running out of GPU Memory (VRAM): A 70B parameter model will not fit on a 24GB GPU. You must choose a model that fits in your available VRAM. Check the model’s page on Hugging Face for its size.
Docker Isn’t Running: The most common error is running docker run and getting `command not found`. You have to start the Docker Desktop application first.
Incorrect Port: Remember that TGI has its native API (port 8080 in our example) and the optional OpenAI-compatible API (port 8000). Make sure your code is pointing to the correct one.
Forgetting the Volume Mount (-v): If you forget this, Docker will re-download the multi-gigabyte model file every single time you restart the container. That’s a painful and slow mistake.
Gated Model Access: If you see an error about not being authorized, it’s because you either forgot the HF token or you haven’t gone to the model’s page on Hugging Face and clicked the button to accept its terms of service.

How This Fits Into a Bigger Automation System

Your TGI server is now the central brain of your company’s AI operations. It’s a foundational piece of infrastructure, a shared resource that everything else plugs into.

Centralized AI Gateway: All your other tools—your CrewAI agents, your Zapier webhooks, your custom scripts—should now point to your TGI server. This gives you a single point of control for logging, model versioning, and cost management (which is now just the cost of electricity/hosting).
Scalability and Redundancy: For mission-critical applications, you can run multiple TGI instances on different machines and put a load balancer in front of them. If one server goes down, traffic is automatically routed to the others.
Enabling Citizen Automators: You can now give non-technical people in your company access to a powerful AI via a simple API endpoint, without them needing to know anything about Docker, GPUs, or Python. They can hit it from Excel, a BI tool, or any other application that can make a web request.

What to Learn Next

You have become a professional AI administrator. You’ve built a fast, scalable, and robust AI service that can power your entire company. You’re serving a powerful, general-purpose model like Llama 3.

But it’s still a generalist. It knows about the world, but it doesn’t know the specific nuances of your business. It doesn’t write in your company’s unique brand voice. It doesn’t know your internal jargon. To get that, we can’t just use a model off the shelf. We have to teach it.

In the next lesson, we will take this powerful base model and **fine-tune** it. We’ll feed it examples of our own company’s data—our best sales emails, our clearest support tickets—and create a new, custom model that is a true expert in *our* business. This is how you build a proprietary AI asset that your competitors can’t replicate.
