AI Systems / Agents / Local-first

Local AI, built to actually do work.

Practical AI infrastructure and agent systems that I use every day: local-first, and built for real operation rather than demos.

AI Systems

One interface. Five systems. Shared context.

AgentHub is the front door to the systems I use every day. Obsidian keeps their knowledge persistent and shared.

You

AgentHub

Unified human ↔ agent interface

Five peer systems. Independent, and able to exchange information.

  • PersonalOS

    Goals, finance, routines, and life admin.

  • CareerOS

    Learning, interviews, roles, and follow-through.

  • FantasyOps

    Data, analysis, and recommendations.

  • Homelab Ops

    Services, health, automation, and incidents.

  • Local AI Platform

    Routing, inference, and local + cloud compute.

Obsidian

Shared Knowledge Base

persistent context • documentation • decisions • plans • runbooks • learnings • agent handoffs

Independent systems • shared memory • durable interfaces

AgentHub is the interface between you and your agents. It dispatches work to five independent peer systems: PersonalOS, CareerOS, FantasyOps, Homelab Ops, Local AI Platform. None of these is nested under another. All five can read from and write to Obsidian, the shared knowledge base.

How it works

From request to remembered result.

  1. 01

    Request work through AgentHub

  2. 02

    Route it to the appropriate agent, system, or compute

  3. 03

    Use domain workflows and shared Obsidian context

  4. 04

    Return the result and persist useful knowledge

Local AI Platform

Local and cloud intelligence, routed per task.

Local

Routine, privacy-sensitive, and available workloads.

Cloud

Specialized, high-complexity workloads.

Capacity, not utilization. Memory is physical per host, not pooled.

* MoE models can exceed 70B total parameters when their quantized weights fit local memory; only a subset of experts is active per token.

About

Nathan Jones

Systems engineer focused on AI infrastructure, agent systems, and practical personal software.

I build systems in my own lab and use them every day, with an emphasis on reliability, usability, and actually operating what I build.

Also a striving photographer.

Places, people, and everyday moments.
