Introducing Multi-Agent Self-Supervision (MASS): Recursive self-improvement through collective intelligence 🧵 Blog: pub.sakana.ai/mass/ Paper: arxiv.org/abs/2610.12176 Code: github.com/SakanaAI/mass
- A new arxiv paper proposes MASS, which alternates evolutionary workflow optimization with supervised fine-tuning on self-generated multi-agent trajectories.
- With Qwen3.6-27B over two MASS cycles, the authors report 1.2-1.6x higher performance per output tokens on four open-ended public benchmarks.
- Multi-agent traces look more training-efficient: a student trained on them beats a single-agent student trained on 1.4x more tokens.
