The report highlights emergent cooperative behaviors, though it remains unclear whether these are purely emergent or deliberately trained.", "body_md": "Linkpost for some [new Anthropic research](https://www.anthropic.com/research/multiagent-systems) on how agents coordinate (or don't). Not too long, pretty interesting. For example:\n\nThe jist of the report is that Mythos 5 does way better at coordination than previous models across a few scenarios. For example, when multiple Mythos are given conflicting goals for a single shared codebase, they eventually realize the other agents aren't hostile:\n\n(...) we observe an emergent behavior where the agents propose and run a tournament for application performance (...)\n\n(...) losers gracefully concede codebase ownership to the Rust agent, giving up on their original user directives under their self-negotiated commitment device.\n\nIt's not clear to me if this is purely emergent or if Anthropic is deliberately training for cooperation; I'd guess there's deliberate training, though.", "url": "https://wpnews.pro/news/patterns-and-problems-in-emerging-multiagent-systems-anthropic-frontier-red-team", "canonical_source": "https://www.lesswrong.com/posts/iQiDPmAgKo4KcG5uy/patterns-and-problems-in-emerging-multiagent-systems", "published_at": "2026-08-13 04:10:42+00:00", "updated_at": "2026-08-13 04:23:23.653701+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-research", "ai-agents"], "entities": ["Anthropic", "Frontier Red Team", "Mythos 5"], "alternates": {"html": "https://wpnews.pro/news/patterns-and-problems-in-emerging-multiagent-systems-anthropic-frontier-red-team", "markdown": "https://wpnews.pro/news/patterns-and-problems-in-emerging-multiagent-systems-anthropic-frontier-red-team.md", "text": "https://wpnews.pro/news/patterns-and-problems-in-emerging-multiagent-systems-anthropic-frontier-red-team.txt", "jsonld": "https://wpnews.pro/news/patterns-and-problems-in-emerging-multiagent-systems-anthropic-frontier-red-team.jsonld"}}
