The Self-Hosted AI Stack
The Self-Hosted AI Stack
Self-hosted AI has matured from a hobbyist pursuit to an enterprise requirement. Privacy regulations, data sovereignty laws, and the desire for predictable costs drive organizations to run AI on their own infrastructure. Local LLM Inference — Ollama, Jan, and GPT4All make running models like Llama, Mistral, and Qwen as simple as installing an app. Support for GPU acceleration, quantization, and model management.
Chat Interfaces — Open WebUI, LibreChat, LobeChat, and AnythingLLM provide ChatGPT-like interfaces for your self-hosted models. Features include conversation history, file upload, RAG integration, and multi-model switching. Knowledge Bases — Onyx, Quivr, and PrivateGPT let you build private RAG systems over your documents — no data leaves your servers.
Development Tools — Tabby (self-hosted Copilot), SearXNG (private search), and Puter (cloud desktop) provide developer infrastructure without external dependencies. TokRepo hosts deployment configs and Docker Compose files for the entire self-hosted AI stack.
Self-hosting AI isn't about avoiding costs — it's about owning your intelligence infrastructure.
Frequently Asked Questions
What hardware do I need to self-host AI?+
It depends on the model size. For 7B parameter models (good for most tasks): 16GB RAM + any modern GPU with 8GB VRAM. For 70B models (GPT-4 class): 64GB RAM + GPU with 48GB VRAM (A6000 or dual 3090). For CPU-only inference: Ollama with quantized models runs on any modern laptop, just slower. Apple Silicon Macs with 32GB+ unified memory are excellent for local AI.
Is self-hosted AI as good as cloud APIs?+
For many tasks, yes. Open-source models like Llama 3.1 70B and Qwen 2.5 72B match GPT-4 on coding, analysis, and general reasoning. They fall short on the most complex multi-step reasoning and creative tasks where Claude Opus or GPT-4o still lead. The gap narrows every quarter. For most business applications, self-hosted models are "good enough" with dramatically better privacy and cost.
What is the easiest way to start with self-hosted AI?+
Install Ollama (one command on Mac/Linux/Windows), pull a model ("ollama pull llama3.1"), then install Open WebUI for a ChatGPT-like interface. Total setup time: under 10 minutes. TokRepo hosts Docker Compose configs that bundle Ollama + Open WebUI + RAG pipeline into a single deployment.
