Fuzzers vs. AI: Comparing Fuzzilli and BigSleep on JavaScript Engines
Summary
Project Zero compares Fuzzilli, a JavaScript engine fuzzer, with BigSleep, an LLM-based bug-finding system, on Chrome's V8. The analysis shows substantial overlap but also complementary strengths, with production overlap around 25% and experimental overlap around 60%, underscoring that fuzzing and AI-based analysis both add value for discovering vulnerabilities before release.
