A post on r/LocalLLaMA points to a new project called Memdoor. Memdoor builds coding agents from small open models. Open means anyone can download the models and run them at home.
The post makes a bold claim. Five small Qwen models, working as a team, matched Anthropic's Fable 5 on a hard coding test. Fable 5 is Anthropic's lead model for coding work. It already tops several big coding charts.
The test is called LiveCodeBench Hard. It checks how well a model solves tough coding problems. The team tried ten problems, five times each. The five-model team scored 9.8 out of 10. Fable 5, working alone, scored 9.
The builders add their own caution here. They say a sample this small makes two close scores read as the same number. The gap could be plain noise, their own words suggest, rather than a real win.
Memdoor splits the work five ways. One small model plans the task. Two models brainstorm ideas. One model writes the code. One model manages the whole run. A sixth worker model fixes bugs as they come up.
Readers found the claim fast. The Reddit post pulled 47 comments. A matching post on Hacker News pulled 257 points and 119 comments. The code itself holds 102 stars on GitHub, with 13 forks.
Qwen is a family of open models built by Alibaba. Memdoor's version, Qwen3.8-27B, stays far smaller than Fable 5. A smaller model costs less to run on everyday hardware.
Running the whole team still costs money and time. Each test run took real compute on a cloud server. The builders shared their full method on GitHub for anyone to check.
This story says something past one small test. Cheap open models now chase a frontier model's coding score. Any builder with a laptop can try the same trick. The claim stays modest, by the builders' own words. The attention around it keeps climbing.
