Setting Up a Local AI Coding Agent with Ollama and Aider
Short summary
A practical guide to running a fully local AI coding agent using Ollama on Windows and Aider inside WSL2 Ubuntu. The author details a CPU-only setup with qwen2.5-coder:14b, including WSL mirrored networking configuration to connect Aider to Ollama. The architecture keeps models on Windows while repos live in the Linux filesystem, avoiding duplicate installations and maintaining privacy.
- •Ollama runs on Windows serving qwen2.5-coder:14b; Aider runs in WSL2 Ubuntu connecting via localhost:11434
- •WSL mirrored networking mode required for Aider to reach Ollama on Windows
- •CPU-only inference works but is slower; setup validated on i7 with 48GB RAM and no dedicated GPU
