Position paper arguing for studying free-formed, self-organizing AI collectives, with small Claude-2.1 simulations (cocktail party, sentence brainstorming, public goods game) suggesting diversity gains and robustness to antisocial behavior.
Problem
Existing multi-agent LLM collectives are human-designed with fixed roles and objectives, leaving open how autonomous AI agents that interact freely develop diversity, norms, and robustness to toxic behavior.
Approach
Let homogeneous LLM agents interact freely (choosing partners and topics) in an open virtual "cocktail party", then show that the resulting heterogeneous clusters improve creative brainstorming, and that cooperative norms built through interaction limit the spread of antisocial behavior in a public goods game.
Key results
- In the sentence-construction task, the valid answer ratio was 0.823 for individual agents vs 0.947 for free-formed collectives (difference 0.124, p<0.001).
- In the public goods game, first-order infected players in non-collective settings dropped contributions from $72.5 to $34, while in collective A the drop was only $20.25 and second-order infection had no effect.
- Distinct agent conversation ratio decreased over 30 rounds (slope -0.006, p<0.001), indicating agents formed tight-knit clusters; tight pairs' conversations diverged semantically over time.

Surprising findings
- Agents in collectives contributed more in the public goods game even before any infection (e.g., pair B contributed $97 vs $72.5 for non-collective agents).
- Gemini Pro agents occasionally produced hybrid pidgin/creole-like outputs mixing languages in free-form interaction.
Limitations
- Small-scale simulation with only 10 agents and a handful of prompts, with few repetitions (20 replicates per scenario) and largely single-model (Claude-2.1) evidence.
- Position paper with exploratory results; claims about scalability and safety are largely speculative.
- Relies on LLM agent behavior in prompt-driven games that may not reflect real-world social dynamics.
