AI coding agents failed spectacularly on new benchmark!

Alibaba tested AI coding agents on 100 real codebases, spanning 233 days each. The agents failed spectacularly.

Turns out passing tests once is easy. Maintaining code for 8 months without breaking everything is where AI collapses.

SWE-CI is the first benchmark that measures long-term code maintenance instead of one-shot bug fixes. Each task tracks 71 consecutive commits of real evolution.

Extremely bearish for AI coding use cases.
