LLM agents use parallel exploration for better software change localization

Researchers have developed a novel approach for LLM agents to localize files for software changes, moving beyond linear exploration to a domain-scoped parallel agentic method. This new strategy aims to improve accuracy for changes spanning multiple subsystems. Initial benchmarks using SWE Bench Pro with Ansible showed that this non-linear, parallel agent system, utilizing a Haiku-class model, significantly outperformed other Haiku models and rivaled larger models like Codex 5.5 High.

    Exploration Structure in LLM Agents for Multi-File Change Localization

    Software engineering tools increasingly rely on LLM based agents to localize files to change to resolve a software issue. Most AI agents explore repositories linearly, that is, visiting one directory or file per step. We postulate that this is a structural mismatch for changes th…
