Self-Hosted AI Server & Agents

An always-on home server that runs local LLMs, AI agents and my own apps, all on hardware I control.

Why I Built It: I wanted hands-on experience running capable AI privately, end to end: the hardware, model serving, agents, networking, and the day-to-day operations work of keeping it all running. It now hosts my local models, my agents, Finance AI Copilot and a personal productivity app.

Hardware

  • Compact always-on server: AMD Ryzen AI Max+ 395 with Radeon 8060S graphics and unified memory shared between CPU and GPU, running headless Ubuntu.
  • Unified memory: system RAM is shared with the GPU, so a 35-billion-parameter model fits entirely in memory.

Model Serving

  • LM Studio serves Qwen3.6-35B-A3B, a mixture-of-experts model, at about 65 tokens per second, with Gemma 4 31B for some agent paths.
  • One large model resident at a time: a deliberate rule that keeps memory predictable and stops models from evicting each other mid-run.
  • Long context: a 262K-token window for document-heavy work and remote coding.

Agents & Automation

  • Four-agent automation pipeline: planner, responder, auditor and memory agents that bridge Discord to the Claude Code CLI, with a config-driven skills loader.
  • Always-on assistant agent: runs in Discord on the local model, with a single front-door channel and per-tool call limits as guardrails.

Apps & Services

  • Life OS: a personal capture and productivity app I built with Next.js, Prisma and SQLite, with an inbox, notes, buckets, a focus engine, video notes and an email-watch agent for Gmail.
  • Private search and alerts: self-hosted SearXNG for search and ntfy for push notifications.
  • Networking: Docker services across a four-machine Tailscale mesh, so every device reaches the server privately.
  • Remote development: VS Code over the tailnet, with local coding models through Roo Code.

What's Next

A six-phase build plan to turn the stack into one coherent assistant: a hardened foundation, a guarded gateway in front of every agent, a structured model of goals and commitments, one unified memory with citations, follow-through on commitments, and a proper interface with evals.
