Self-Hosted AI

Private model hosting and GPU experimentation using local infrastructure rather than relying entirely on remote AI services.

Overview

What it is

The self-hosted AI project uses the homelab’s NVIDIA GPU capacity to experiment with local inference, private model serving, API-compatible endpoints and application integrations.

Goals

Learn GPU passthrough, model/runtime compatibility, container orchestration, authentication, performance limits and where local inference is genuinely useful.

Private by default

Local inference can keep selected workflows and datasets inside the lab.

Infrastructure learning

The project is as much about GPU/runtime integration as it is about models.

System Components

Stack & Capabilities

RTX A4000

Dedicated 16GB workstation GPU for CUDA workloads and local model inference.

LocalAI

Self-hosted model/API layer used to expose local inference services.

Containerization

AI services run inside the existing Proxmox and Docker environment.

Future RAG

A natural next step is retrieval over locally hosted documentation and project knowledge.
