Closed-loop coding agents
Alibaba built a coding model that learns from its own users. The numbers are hard to ignore.
Alibaba's new coding model Qwen-Coder-Qoder beats Cursor Composer-1 on the Qoder Bench benchmark. Production metrics show a 3.85% code retention increase, a 61.5% drop in tool errors, and a 14.5% reduction in token use. The model trains on real agent traces through a rewarder-attacker framework against reward hacking.
