Latest update (11-08 04:50): Co-Design Bench shows AI coding agents fully finish only about one in four real tasks

Overview: Researchers from Alibaba and several Asian universities built Co-Design Bench, a benchmark of real user change requests for coding agents. In tests of ten models, the best, GPT-6 Astra, meets about 70 percent of task requirements on average but is fully correct in only 26.4 percent of tasks.

The authors say performance drops as tasks combine more types of changes, and that results also depend on the harness the model runs in.
