AI in IT has two modes: genuinely useful and massively overhyped. Here's where it lands in my actual workflow.

Ollama — Local LLM for Everything Private

Ollama runs large language models on your own hardware. I use it for:

  • Writing one-off scripts (Bash, Python, PowerShell) from a description
  • Explaining unfamiliar log output or error messages
  • Drafting documentation from rough notes

The models I keep loaded: Llama 3.1 8B for fast queries, Qwen2.5-Coder 14B for code tasks, Mistral 7B when I want a second opinion.

Setup takes ten minutes on any machine with 16GB RAM. A dedicated GPU speeds up inference significantly — the NVIDIA RTX 3060 12GB handles 13B models at usable speed.

Claude / ChatGPT — For Tasks That Need Reasoning

When I need multi-step reasoning — designing a network architecture, reviewing a firewall ruleset for gaps, debugging a complex Ansible playbook — I use Claude or GPT-4o. Local models at 7–13B can't match the reasoning depth here yet.

Fabric — AI Pipeline for the Terminal

Fabric is a command-line tool that pipes text through AI prompts. My daily use: pipe a log file through a "summarize errors" prompt, or pipe a long config into a "spot the security issues" pattern.

cat /var/log/syslog | fabric --pattern analyze_logs

It connects to Ollama or any OpenAI-compatible API.

n8n — Workflow Automation with AI Steps

n8n is a self-hosted automation tool with an AI agent node. I use it for:

  • Parsing alert emails and creating tickets automatically
  • Summarizing monitoring alerts before they hit my phone
  • Pulling data from APIs and formatting it into reports

Run it as a Docker container. The n8n + Ollama combo on a mini PC handles all of this offline.

Where AI Wastes My Time

Asking AI to diagnose production outages in real time. It hallucinates plausible-sounding but wrong command flags. For live troubleshooting, documentation and man pages are still faster. AI is a draft tool, not an oracle.

The Hardware Minimum for Local AI

  • 16GB RAM — runs 7B models in CPU mode
  • 32GB RAM + RTX 3060 12GB — runs 13B models fast enough to be useful
  • 64GB RAM + RTX 4070 — runs 34B models, covers most tasks without cloud APIs

The Kingston Fury 32GB DDR4 kit is the upgrade I'd make first if you're RAM-limited.
