World of SWECraft: Agent Collaboration at Scale via Simulated Software Worlds

Read the original on arXiv Computation and Language →

The paper introduces Software World, a framework that simulates multi‑agent collaboration within realistic software ecosystems. It generates environments of interdependent Python packages and lets agents maintain and improve them, measuring collective speedup in hidden dependent packages. Experiments across three worlds and eight models show that performance improvement scales with inference‑time compute, with the best model boosting downstream efficiency by up to 31%.

MASBench: Benchmarking LLM-based Multi-Agent Collaboration under Partial Observability

MASBench is a benchmark for evaluating large language model (LLM)-based multi‑agent systems (MAS) under partial observability, a realistic constraint where agents only see limited environmental information. The benchmark is structured into three progressive task categories—Reasoning, Scheduling, and Game—and assesses three collaboration mechanisms: Protocol, Memory, and Routing. It provides deterministic evaluation metrics such as performance score, communication cost, and cost effectiveness, and includes empirical results across various LLM backbones to guide effective MAS design.

OpenCollab: A Multi-Agent Coding Framework with Programmable Collaboration and Controllable Runtime

OpenCollab is a multi‑agent coding framework that unifies organization design, enforces experimental control on a shared runtime, and tracks execution via fine‑grained event streams. It introduces the metric Adherence to measure whether the declared organization is actually realized, showing that small configuration changes can shift adherence from 47.2% to 97.2%. Experiments demonstrate that a two‑coder workflow built on OpenCollab achieves new state‑of‑the‑art performance against mainstream harnesses while using the fewest tokens, and that a well‑designed organization can outperform strong existing harnesses.
