Every model, one door.

A self-hosted LLM lab. Local models run on an old Xeon with no GPU; frontier models are proxied in. Chat, observe and build through a single OpenAI-compatible surface — behind Cloudflare Access.

Lab = Models + Plumbing

The models are the soul. The plumbing keeps them reachable.

Three thin layers, each replaceable. Nothing here is clever; it is simply kept running.

01 · llama.cpp

Local inference

Gemma 4 E4B and Qwen3 30B-A3B served from CPU RAM on a Proxmox VM. One model resident at a time; swaps are logged.

02 · LiteLLM

One API for all

Local and hosted models (GPT, Claude, Gemini, OpenRouter free tier) behind a single /v1. Keys, budgets and routing live in config.

03 · Cloudflare Access

Private by default

No open ports. Every hostname sits behind a tunnel and an identity check; the API takes a bearer key on top.

Design approach

Every request is visible. Every watt is counted.

Chat through Open WebUI

One interface for every model in the lab. Switch between a local Gemma and a hosted Claude mid-conversation; history, files and prompts stay on the box.
