Skill-MAS: Evolving Meta-Skill for Automatic Multi-Agent Systems

arXiv:2606.18837v1 Announce Type: cross Abstract: Large Language Model (LLM)-based automatic Multi-Agent Systems (MAS) generation has become a crucial frontier for tackling complex tasks. However, existing methods face a dilemma between model capability and experience retention. Inference-time MAS leverages frozen frontier LLMs but repeats identical searches without learning from past experience. Conversely, Training-time MAS internalizes experience via gradient updates but is constrained by the low capability ceiling of smaller models, and is hard to scale to large frontier LLMs. To bridge th

Why this matters
Why now

The rapid advancement of Large Language Models has made LLM-based Multi-Agent Systems a crucial frontier, but current approaches struggle with balancing model capability and experience retention.

Why it’s important

This research addresses a fundamental limitation in AI agent development, potentially enabling more capable and efficient autonomous systems that learn from past interactions.

What changes

Existing trade-offs between using high-capability models versus models that retain experience could be overcome, accelerating the practical application of advanced multi-agent AI.
