qwen2.5-coder is too slow for Claude Code on a Mac. Here's the fix.

Claude Code does not care where the model lives. Point it at a local model and it works with no network. I tested that at 35,000 feet, picked the wrong model first, and swapped mid-flight.

TL;DR

Claude Code reads two environment variables to decide where its model lives. Point them at Ollama and it runs fully offline.

I tested this on a real flight. Berlin, May 13, wifi off, cabin door closed.

I started on qwen2.5-coder:14b. It was too slow for anything agentic. One tool call sat for 25 seconds, the next for 52.
