Decision brief
LLMFuzzer is an open-source fuzzing framework tailored for testing the robustness of Large Language Models through their APIs.
Good fit when
- When ensuring custom LLM integrations are secure against unexpected inputs and edge cases
- During development phases of apps that heavily rely on LLMs for critical functionalities
Avoid when
- If the project exclusively uses proprietary closed-source models without accessible APIs
- For general software testing not involving interactions with or security checks of language models
