The author evaluated Qwen 3.8 Flash Next (IQ3_XXS, IQ3_S, and the original Alibaba Cloud version accessed via OpenRouter API) using four coding assistants: GitHub Copilot, Qwen Code, OpenCode, and Codex Desktop. Despite identical model and prompt, each tool generated distinct outputs, and repeated runs of GitHub Copilot yielded differing results each time. The experiment highlights the influence of coding‑tool implementation on model behavior, though the test was limited in scope.
