Introducing Patch the Planet

Trail of Bits describes the first week of Patch the Planet, a partnership with OpenAI Daybreak pairing engineers and maintainers with frontier models like GPT-5.5-Cyber and Codex to find and fix bugs in open-source projects such as curl, aiohttp, RustCrypto, PyCA, python.org, PyPI, and Sigstore. It reports concrete outcomes: GPT-5.5-Cyber autonomously building a full fuzzing lab with OS-backpressure harnesses in under a day, Codex-driven CVE variant analysis and cross-library differential testing that found an AES-GCM issue in PyCA and X.509 discrepancies, 64 pull requests and 51 issues filed, and aiohttp maintainers fixing eight privately-reported bugs within hours. It closes with maintainer guidance on deduplication, false-positive filtering, and severity correction for the flood of AI-generated reports.

TL;DR Trail of Bits and OpenAI's Daybreak initiative use GPT-5.5-Cyber and Codex to autonomously fuzz, variant-analyze, and differentially test major open-source projects, landing real patches while offering maintainers a playbook for triaging AI-found bugs.
