About PromptFuzz

Prompt Fuzzing for Fuzz Driver Generation PromptFuzz is an automated tool that generates high-quality fuzz drivers for libraries via a fuzz loop constructed on mutating LLMs' prompts. The fuzz loop of PromptFuzz aims to guide the mutation of LLMs' prompts to generate programs that cover more reachable code and explore complex API interrelationships, which are effective for fuzzing. PromptFuzz is currently regarded as the leading approach for generating fuzz drivers both in academia and industry. The fuzz drivers generated by PromptFuzz achieved a branch coverage of 40.12\% on the tested libraries, which is 1.61x greater than OSS-Fuzz and 1.67x greater than Hopper. Besides, PromptFuzz detected 33 valid security bugs from 49 unique crashes. Relase Notes: Release v1.0.0. Support AFLPlusPlus, more libraries and fixed many panic bugs! (2026-04-10) Upgrade Clang and LLVM versions to 18! (2025-06-07) Upgrade asyncopenai sdk version to 0.28 to support OPENAI interface new features. (2025-06-05) Support OpenAI specification!
