How much reverse engineering code do AI models write?
190,658 of the 450,474 commits in 838 public reverse engineering projects credit an AI, or 42% of them. Claude is credited on 183,907 and GPT / Codex on 10,022.
We count the AI co-author credits that coding tools write into each project's public git history. Every listed project page shows its own figures, and the census is rerun about once a week.

A commit crediting two models counts once for each. These figures show how much a model is used, and the models page covers how well they do on benchmarks.
AI-credited commits week by week
Reports from 27 October 2026 said Anthropic had steered Claude Code away from recreating specific existing games (PCWorld).

What this can and can't tell you
- It is a minimum. A commit counts only if it names an AI as co-author or author, and many tools and people leave that out.
- Commit counts measure activity. An agent that commits every few minutes counts for far more than a person who squashes a week of work, and the 10 busiest projects account for 39% of AI-credited commits.
- It doesn't show whether the result works. For that, see each project's reported outcome.
- Each commit counts once. Forks repeat their parent's history, so commits are matched by hash and forks are grouped into one project by their first commit.
- The repositories are the 859 that our discovery had found on GitHub by 10 Nov 2026: 508 listed in the directory and the rest awaiting review. Recently active repositories are easier to find, so recent weeks can look busier than they were. Figures for individual projects are published only for listed entries.
