Qwen 3.8 27B vs DeepSeek V4 Flash — I Built the Same Apps With Both Locally

Qwen 3.8 27B just dropped, so I ran it against DeepSeek V4 Flash 0731, a model ten times its size, with both downloaded and running locally on my Mac Studio. I gave them three coding tasks of increasing difficulty: a weather dashboard pulling live data, a tower defense game, and an Excel style spreadsheet with working formulas. The 27B model held its own and on the hardest test it was the only one that produced something that actually worked. 👉 Github Repo for all tests, results, machine specs, and model performance specs: https://github.com/Barty-Bart/qwen-vs-deepseek-local-coding 👉 One-on-one coaching, team coaching, or agent builds: https://workingmodels.ai/start 📬👀 Subscribe to my blog for more tests, tips, and walkthroughs: https://blog.workingmodels.ai/ 👉 Watch all my Local AI videos: https://www.youtube.com/playlist?list=PLi7jtY2ZZqRaidYBIucDnKnhD7Jmt-2sY 👉 Connect with me: https://x.com/bartslodyczka
