Ran Qwen 3.5 27B via Ollama as a persistent background agent for 30 days. Not a demo. Honest results.

I wanted to know if a local LLM could handle recurring background tasks reliably over an extended period - not as a chatbot, but as a persistent worker that runs scheduled jobs, maintains context across sessions, and routes tool calls without human prompting. So I ran it for 30 days on real tasks from my actual workflow. Model: Qwen 3.5 27B via Ollama. Hardware: Mac with 32GB unified memory, but the architecture works on any machine that can run a 27B+ model locally. Setup Each agent runs in a persistent workspace with its own memory, skills, and MCP sidecars.
