HyperAgent

About

HyperAgent came out of FPT Software's AI4Code research group as a generalist alternative to single-purpose repair or localization systems: one four-agent pipeline switches between patch generation and fault-prediction modes depending on the task. A Planner decomposes the issue, a Navigator locates relevant code using Zoekt and universal-ctags indexes, a Code Editor writes changes, and an Executor runs them in a Jupyter kernel, with each agent configurable to a different LLM. It reported 31.4% on SWE-Bench Verified, 25% on Lite, 53.3% Pass@5 on RepoExec, and 249 fixed Defects4J bugs. The repo has seen no commits since November 2024 and functions as archived research code accompanying the arXiv paper.
