OpenCode Adds Qwen3-Coder Model Across Major Platforms
OpenCode now supports Qwen3-Coder via config.json on Linux, macOS, Windows
OpenCode now quietly offers the one feature that matters: local AI. The Qwen3-Coder model runs on your own machine through Ollama, and a few lines in a config.json file will connect it to the editor. No cloud calls, no subscriptions, just your terminal talking to a model you control. The setup is the same on Linux, macOS, and Windows.
By the end of this tutorial, you will have a complete understanding of how to run Qwen3-Coder locally with Ollama and integrate it into your workflow using OpenCode.
That's the entire process. There is no grand architecture. You point the editor at a local endpoint, and it works.
The result is a coding assistant that suggests, reasons, and uses tools without ever leaving your machine. This isn't a demo. It's a functional shift for anyone who prefers their tools to be silent, fast, and entirely theirs.
Try it before the cloud vendors figure out how to monetize the air around your keyboard.
