Architecture

How It's Built

🖥️ Hardware

Mac Mini M2 (8GB RAM, 256GB SSD) — purchased used for $400. Silent operation, ~7W power draw ($5/year), 99.7% uptime since deployment.

Self-hosted on local network. No cloud hosting costs. Full data ownership.

⚙️ Software Stack

OpenClaw — Self-hosted, running on port 18789. YAML-based skill definitions. Gateway with auto-healing.

Model Routing — Smart selection based on task complexity. Heartbeats use Kimi ($0.80/M tokens), strategy uses Opus ($15/M tokens).

Model Routing Strategy

The key to 83% cost savings: use the right model for the right task.

Task Type Model Cost/M Tokens Usage
Monitoring/Heartbeats Kimi K2.5 $0.80 35%
Data Parsing/Extraction Claude Haiku $0.80 25%
Code Generation Claude Sonnet 4.5 $3.00 20%
Strategy/Reasoning Claude Opus 4 $15.00 15%
Simple Q&A Gemini Flash $0.15 5%

Blended average: ~$2.50 per 1M tokens (vs $15 if using Opus for everything) = 83% savings

The Numbers

Monthly Operating Costs

Complete transparency on what it actually costs to run this system.

API calls (all models) $47.20
Mac Mini power (~7W) $0.42
Telegram Bot API $0.00
Buffer (content scheduling) $6.00
Domain + email $12.00
Total Monthly Operating Cost $65.62

"If we used Claude Opus for everything, our monthly cost would be $380-420. With smart routing, we pay $47. That's not optimization — that's the difference between viable and not viable."
