How to Deploy Llama 2 on DigitalOcean for $5/Month

Description and use

Deploying Llama 2 7B on DigitalOcean for $5/month cuts API costs to <$5/month using 4‑bit quantization and a Dockerized Flask API.

High cost of commercial AI APIs for high‑volume token workloads.

Running Llama 2 7B quantized on a $5/month Droplet reduces inference cost from ~$90/month to <$5/month, while providing a production‑grade REST API.

Create a $5/month DigitalOcean Droplet (Ubuntu 22.04, 1 GB RAM, 25 GB SSD).
SSH into the Droplet and update packages.
Install Docker and Docker‑Compose.
Create a non‑root user and add to docker group.
Create a project directory and write a Dockerfile that builds llama.cpp, installs Flask, downloads the 4‑bit quantized model, and exposes port 5000.
Write a simple Flask API server (api_server.py) that starts llama.cpp and handles inference requests.
Build the Docker image and run the container.
Verify the API is reachable (e.g., curl http://localhost:5000/health).
Optionally scale by increasing Droplet size or adding replicas.
Monitor usage and cost via DigitalOcean dashboard.
Use the REST API in your applications for content generation, support automation, or semantic search.

Run it yourself? That's $5/month, plus electricity you're paying for anyway.

Llama 2 7B quantized fits comfortably on $5/month hardware.
