Qwen 3.8-27B model struggles with agentic coding on local hardware

A user attempted agentic coding on a Macbook Air M2 with the Qwen 3.8-27B model, a process that took an extensive 63 hours to produce a functional, albeit buggy, flight simulator. In contrast, using cloud-based platforms like Google AI Studio and Qwen Studio for the same task resulted in significantly faster completion times and more polished outputs, with Google AI Studio achieving a one-shot success in 20 minutes.
