The setup proxies requests to OpenAI's GPT-4o and Anthropic's Claude 3.5 Sonnet, centralizes API key management, and provides an admin dashboard for tracking per-user costs and issuing virtual keys.", "body_md": "As developers, we’ve all been there: you build an AI-powered feature, deploy it to production, and suddenly get slapped with a massive OpenAI or Anthropic API bill because a user ran a recursive loop, or because your team shared raw API keys across staging environments. 💸\n\nSharing master API keys is a major security risk, and tracking individual user costs across multiple models (GPT-4o, Claude 3.5 Sonnet, Llama-3) is a management nightmare.\n\nThere is a better way. By self-hosting **LiteLLM**, you can spin up a unified, private **LLM Gateway** that acts as a proxy between your applications and your AI providers. \n\nWith LiteLLM, you get:\n\nIn this guide, we'll deploy a production-ready LiteLLM Instance with a beautiful UI Admin Dashboard on a high-speed [Vultr High-Performance Cloud Instance](https://www.vultr.com/?ref=9925661) in under 10 minutes.\n\nWhen proxying API requests, **latency is everything**. Adding a proxy layer shouldn't introduce lag. [Vultr's High-Performance Cloud](https://www.vultr.com/?ref=9925661) offers high-frequency CPU cores and NVMe storage in over 32 global locations. This means your proxy can be co-located right next to your target audience (or your main application servers) to ensure sub-millisecond routing overhead.\n\nOnce your instance is ready, copy the IP address and connect to it via your terminal:\n\n```\nssh root@YOUR_VULTR_IP\n```\n\nUpdate your system packages and install Docker to manage our containers easily:\n\n```\nsudo apt update && sudo apt upgrade -y\nsudo apt install -y docker.io docker-compose\n```\n\nVerify the installation:\n\n```\ndocker --version && docker-compose --version\n```\n\nCreate a dedicated directory for LiteLLM:\n\n```\nmkdir litellm-gateway && cd litellm-gateway\n```\n\nNow, create a `litellm_config.yaml` file. This is where you configure the models you want to proxy. For this demo, we'll configure OpenAI's GPT-4o and Anthropic's Claude 3.5 Sonnet:\n\n```\nmodel_list:\n  - model_name: gpt-4o\n    litellm_params:\n      model: openai/gpt-4o\n      api_key: \"os.environ/OPENAI_API_KEY\"\n  - model_name: claude-3-5-sonnet\n    litellm_params:\n      model: anthropic/claude-3-5-sonnet-20240620\n      api_key: \"os.environ/ANTHROPIC_API_KEY\"\n\n# Configure global database for key management and logs\nrouter_settings:\n  routing_strategy: latency-based-routing\n\ngeneral_settings:\n  master_key: \"os.environ/LITELLM_MASTER_KEY\"\n```\n\nWe will set up three components:\n\nCreate a `docker-compose.yml` file in the same directory:\n\n```\nversion: '3.8'\n\nservices:\n  db:\n    image: postgres:16-alpine\n    container_name: litellm-db\n    environment:\n      POSTGRES_DB: litellm\n      POSTGRES_USER: litellm_user\n      POSTGRES_PASSWORD: super_secret_db_password\n    volumes:\n      - pgdata:/var/lib/postgresql/data\n    ports:\n      - \"5432:5432\"\n    restart: always\n\n  litellm:\n    image: ghcr.io/berriai/litellm:main-latest\n    container_name: litellm-proxy\n    ports:\n      - \"4000:4000\"\n    volumes:\n      - ./litellm_config.yaml:/app/config.yaml\n    environment:\n      - DATABASE_URL=postgresql://litellm_user:super_secret_db_password@db:5432/litellm\n      - LITELLM_MASTER_KEY=sk-your-super-secure-master-admin-key-12345\n      - OPENAI_API_KEY=your_actual_openai_api_key_here\n      - ANTHROPIC_API_KEY=your_actual_anthropic_api_key_here\n    depends_on:\n      - db\n    command: [\"--config\", \"/app/config.yaml\", \"--detailed_debug\"]\n    restart: always\n\nvolumes:\n  pgdata:\n```\n\n💡 *Note: Replace `your_actual_openai_api_key_here` and `your_actual_anthropic_api_key_here` with your real API keys, and change the `LITELLM_MASTER_KEY` to a secure, random string.*\n\nRun the Docker stack in detached mode:\n\n```\ndocker-compose up -d\n```\n\nCheck if everything is running correctly:\n\n```\ndocker-compose ps\n```\n\nYour gateway is now active!\n\n`http://YOUR_VULTR_IP:4000/ui`.` LITELLM_MASTER_KEY` you configured in your `docker-compose.yml` (e.g., `sk-your-super-secure-master-admin-key-12345`).\nFrom this dashboard, you can:\n\nTo consume your self-hosted gateway, you simply point your existing OpenAI SDK to your Vultr server. No code changes required!\n\n``` python\nfrom openai import OpenAI\n\nclient = OpenAI(\n    api_key=\"sk-the-virtual-key-you-created-in-dashboard\",\n    base_url=\"http://YOUR_VULTR_IP:4000\"\n)\n\n# Call any model you defined in your LiteLLM config!\nresponse = client.chat.completions.create(\n    model=\"claude-3-5-sonnet\",\n    messages=[{\"role\": \"user\", \"content\": \"Explain quantum computing in 2 sentences.\"}]\n)\n\nprint(response.choices[0].message.content)\n```\n\nBefore pointing production applications to your gateway, ensure you secure it with SSL. You can easily install **Nginx** and **Certbot** on your Vultr instance to get a free Let's Encrypt SSL certificate:\n\n```\nsudo apt install -y nginx certbot python3-certbot-nginx\n```\n\nConfigure Nginx to reverse proxy traffic from port `80`/` 443` to `http://localhost:4000` and run `sudo certbot --nginx` to enable HTTPS.\n\nReady to get your team's AI costs under lock and key?
