AnyAct: Universal Action for Self-Evolving Agents

Read the original on arXiv AI →

AnyAct introduces a universal action layer that consolidates diverse tool capabilities into a self‑evolving action space for AI agents operating in open‑world environments. It tackles the scale dilemma, tool non‑stationarity, and heterogeneous feedback by using hierarchical progressive retrieval and test‑time reliability evolution, while a heterogeneous observation grounding module unifies multi‑modal feedback. Evaluations on LiveMCPBench and the newly created OSMCP benchmark show state‑of‑the‑art performance, with significant gains in task success rate and reduced execution steps, especially for models with limited native capabilities.

Evolving Self-tuning Benchmarks for Long-Horizon Tool Use

The paper introduces TURTLE, an Unsupervised Environment Design framework that evolves tool‑use tasks for AI assistants by using a proposer, solver, and feedback generator powered by large language models. TURTLE automatically generates self‑tuning, long‑horizon benchmarks that increase task difficulty, diversity, and failure modes across multiple applications. Experiments on AppWorld, τ‑Bench, and AutomationBench demonstrate significant gains in hard task percentages and broader reasoning challenges.

CoworkOS:Scaling Agent Coworkers for Real-world Automation

CoworkOS is a general‑purpose harness designed for long‑horizon real‑world automation, separating task strategy from execution management. Its three‑layer architecture allows direct execution or delegation to subagents, while a shared application layer lets humans and agents collaboratively edit documents, designs, and 3D scenes. The system incorporates hierarchical workspaces and persistent semantic memory to maintain continuity across agents and sessions, and demonstrates strong performance across 12 benchmarks and six application categories, outperforming leading agents like Codex and DeepSeek Harness.
