Its early research gains make the idea concrete, while uneven benchmark transfer and just two cycles leave long-run reliability and real-world costs unresolved.\n\nSakana AI co-founder and CEO David Ha has made self-evolving AI one of the Tokyo lab's research interests. A new project from [Sakana AI](https://sakana.ai/?ref=runtimewire) and UC Berkeley, described on [Sakana AI's MASS project page](https://pub.sakana.ai/mass/?ref=runtimewire), tests that idea: use a model to organize research agents, let it judge their work, then train the model on the strongest team results.…", "url": "https://wpnews.pro/news/sakana-ai-trains-a-model-on-its-agents-collective-research-work", "canonical_source": "https://runtimewire.com/article/sakana-ai-mass-agent-teams-self-improvement", "published_at": "2026-10-11 23:04:33+00:00", "updated_at": "2026-10-11 23:37:01.004901+00:00", "lang": "en", "topics": ["ai-agents", "ai-research", "artificial-intelligence", "machine-learning"], "entities": ["Sakana AI", "UC Berkeley", "MASS", "David Ha"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/sakana-ai-trains-a-model-on-its-agents-collective-research-work", "markdown": "https://wpnews.pro/news/sakana-ai-trains-a-model-on-its-agents-collective-research-work.md", "text": "https://wpnews.pro/news/sakana-ai-trains-a-model-on-its-agents-collective-research-work.txt", "jsonld": "https://wpnews.pro/news/sakana-ai-trains-a-model-on-its-agents-collective-research-work.jsonld"}}
