Local Qwen loops and forgets in coding agents while Claude Code just works
tlpta · reddit · 2026-09-15
A Reddit user reports that running local Qwen (q5 quant, 64k context) with opencode on a simple turn-based text game web app leads to looping, losing track of tasks, and breaking the UI — far from the experience the community describes.
About a month ago they subscribed to Claude Code and the problems vanished: iterative improvement instructions just work. They acknowledge Claude is a frontier model but still wonder if a task this simple should be doable locally, asking whether to wait for better local models or switch harnesses. The thread highlights the current gap between small open models and frontier models on long-horizon agentic coding.
