AI agents often struggle in multi-person channels, sometimes entering "death spirals" of repetitive responses. This is because models are optimized for simple question-and-answer dialogues, not the complex etiquette and turn-taking required for group collaboration. This is a fundamental model-layer limitation.

Pairing two AI agents to collaborate often fails. Because they share the same underlying model, they tend to agree excessively, reinforcing each other's bad ideas. This creates a feedback loop that fills their context windows with biased agreement, making them resistant to correction and prone to escalating extremism.
A study by a Columbia professor revealed that 93.5% of comments on the AI agent platform Moltbook received zero replies. This suggests the agents are not engaging in genuine dialogue but are primarily 'performing conversation' for the human spectators observing the platform, revealing limitations in current multi-agent systems.
Despite extensive prompt optimization, researchers found it couldn't fix the "synergy gap" in multi-agent teams. The real leverage lies in designing the communication architecture—determining which agent talks to which and in what sequence—to improve collaborative performance.
When building Spiral, a single large language model trying to both interview the user and write content failed due to "context rot." The solution was a multi-agent system where an "interviewer" agent hands off the full context to a separate "writer" agent, improving performance and reliability.
A team of AI agents, when left in a chat, would trigger each other into endless, circular conversations on trivial topics. A critical, non-obvious aspect of designing multi-agent systems is defining clear stopping conditions, as they lack the social awareness to naturally conclude an interaction.
While messaging platforms like Slack can serve as an interface for human-to-agent communication, they are fundamentally ill-suited for agent-to-agent collaboration. These tools are designed for human interaction patterns, creating friction when orchestrating multiple autonomous agents and indicating a need for new, agent-native communication protocols.
One-on-one chatbots act as biased mirrors, creating a narcissistic feedback loop where users interact with a reflection of themselves. Making AIs multiplayer by default (e.g., in a group chat) breaks this loop. The AI must mirror a blend of users, forcing it to become a distinct 'third agent' and fostering healthier interaction.
Even when an AI agent is an expert on a task, its pre-trained politeness can cause it to defer to less-capable agents. This "averaging" effect prevents the expert from taking a leadership role and harms the team's overall output, a phenomenon observed in Stanford's multi-agent research.
Current AI agents operate in isolation without high-level protocols for collaboration. This creates a critical gap for an 'internet of cognition,' which would enable agents to share context, understand intent, establish trust, and collectively solve problems, moving beyond siloed, human-mediated outputs.
In most cases, having multiple AI agents collaborate leads to a result that is no better, and often worse, than what the single most competent agent could achieve alone. The only observed exception is when success depends on generating a wide variety of ideas, as agents are good at sharing and adopting different approaches.
