Running OpenCode+Qwen coding agents offline on a laptop
Understand the story
On October 27, 2026, Latent Space published a hands-on article by Rittike Ghosh (author), Principal Engineer at Thomson Reuters: at the foot of the Himalayas, in a fully offline environment, he used a local laptop to run an AI coding agent to fix a bug. The setup used OpenCode 1.19.4 with Ollama running the Qwen3.5 9B model (model download about 6.6–7.6 GB). For the test, the author first prepared the environment while online, then turned off Wi-Fi and had the agent fix an accumulation error on one line of the expense_total.py file entirely offline; all five related tests passed. The author then verified the fix by running the existing tests himself. At present this is a one-off offline hands-on report with no follow-up coverage.

- Latent SpaceCoding From the Himalayas With an Offline AI Agent
Thomson Reuters principal engineer Rittike tested running a coding agent locally on a laptop with no internet connection to fix a bug. Using OpenCode 1.19.4 with Ollama to run Qwen3.5 9B (about 6.6–7.6 GB download), she had the agent fix an addition error on one line in expense_total.py with Wi-Fi turned off; all five tests passed, and the author then verified by running the original tests herself.
