AutoDev is an AI programmer tool launched by Microsoft. It can autonomously generate and execute code based on user-defined goals without human intervention. Based on the GPT-4 model and using a multi-Agent collaboration mechanism, AutoDev achieves a Pass@1 rate of 91.5% for code generation tasks and 87.8% for test generation tasks in the HumanEval benchmark, with performance surpassing the GPT-4 baseline by more than 30%. AutoDev aims to enhance development efficiency and lower the programming threshold.
