Community coverage notes Alibaba open-sourced its internal AI code-review assistant as Open Code Review (github.com/alibaba/open-code-review; npm @alibaba-group/open-code-review at 1.12.0). The CLI reads Git diffs, uses a tool-using agent for line-level structured comments, supports ocr scan for whole-file audits, and plugs into Claude Code, Codex, and Cursor. Official bench: 50 repos / 200 PRs / 10 languages with 1,505 annotated issues; same base model yields higher Precision and F1 than general-purpose Claude Code at ~1/9 the tokens, trading some recall for less noise.
