Tuning a Local Coding Agent: Oh My Pi and Qwen3.8-27B on Two RTX 3090s

Running a coding agent at home

Coding agents read your repository, run commands, edit files and keep going until a task is done. Most people use them through a subscription or an API that bills per token. You can also run one on your own machine, with no usage bill, and your code stays home.

I’ve started to use Oh My Pi , usually called omp, a fork of the open-source Pi coding agent, with Qwen3.8-27B, an open-weights model that fits on consumer graphics cards. The server is vLLM on two used RTX 3090s.
