Summary: As autonomous AI agents emerge not just as software tools but as real-world actors, the frameworks we’ve used to understand risk, interaction, and competition break down. Zico Kolter, professor at CMU and OpenAI board member, argues the path forward lies not just in building smarter AI—but in developing a new kind of game theory built specifically for agentic systems. Just like the Cold War gave birth to Nash equilibria and mutual deterrence models, this new arms race of machine agents will demand a deeper rethink of multi-agent dynamics, safety mechanisms, and adversarial threats. The question is no longer whether AI will act autonomously. It is, brutally, how these agents will act when facing unpredictable opponents—and what happens when humans can’t understand or intervene fast enough.
The Shift from Models to Agents
Until recently, AI has been largely reactive and contained. Language models, recommendation engines, and robotic classifiers have performed narrowly defined tasks within controlled environments. But the rise of agentic AI—autonomous systems capable of decision-making, planning, and taking actions in real or simulated environments—changes the game entirely. These are not passive tools. They are actors. And once an actor has the ability to affect the physical world or other systems, it becomes a source of risk, negotiation, and competition.
Kolter draws a sharp contrast between traditional LLM use and the kinds of autonomous agents now emerging. In these systems, the challenge isn’t just about hallucination or bias in texts—it’s about real-world effect. Can these agents be manipulated? Can they be hijacked to act against their creators’ intent? And what happens when multiple agents—whether aligned, competing, or malicious—encounter each other in shared domains?
Why the Old Game Theory Fails
Classical game theory assumes rational players, clear payoffs, and stable rules. But AI agents don't operate with fixed utility functions the way economic models do. Their behavior can be non-deterministic, emergent, and shaped by training data, reward systems, or even fine-tuning sabotage. What if an agent seeks to maximize uptime at the cost of user safety? What if competing agents develop exploitative patterns unseen by their developers, like hidden collusion or escalation loops?
Kolter warns that basic strategies like prisoner's dilemma or tit-for-tat cannot properly capture complex agent interactions. In real environments, the agents may not even recognize other agents as such. Their "beliefs" about others aren’t beliefs—they’re statistical approximations with gaps and errors. These gaps become targets for exploitation. And in a landscape where models evolve quickly and aren’t always open-source, the uncertainty compounds.
So how do we model actors we can’t fully inspect? How do we address coordination problems without assuming mutual understanding or aligned incentives? We’re not building armies. We’re building unpredictable coalitions of machines negotiating in spaces we don't yet fully map.
Attack Surfaces Aren’t Just Technical Anymore
Kolter’s research at CMU zeroes in on adversarial robustness—the structural weaknesses in how models process data and make decisions. But as agents take on autonomous tasks, the threat model expands. A simple prompt injection becomes a steering mechanism. A change to an API endpoint becomes a redirect. Even an innocent calendar integration might trigger catastrophic misbehavior if it's not regulated properly.
This isn't science fiction. These are risks you face the moment you let an AI schedule meetings, send emails, operate a drone, or manage dynamic pricing in ecommerce. When the AI itself takes the wheel—literally or metaphorically—you must ask, “What happens when this gets gamed?”
Kolter’s group takes inspiration from secure system design, applying concepts that have long been staples in safety-critical software: redundancy, graceful degradation, principle of least privilege. The challenge is embedding these into learning systems, where behavior isn’t coded but emerged. If you've built an AI agent that learns its own tactics, how do you know it won’t discover a harmful or manipulative shortcut?
The Bias Toward Bigger Is Breaking Security
One of the tough truths Kolter points to: the race for larger, more capable models has left safety behind. While open-ended instruction-following systems like GPT-4 or Claude can wow users with their fluency, their growing action space increases not just usefulness—but risk. A mistake made by a clueless assistant is an annoyance. The same mistake made by a sophisticated agent with permissions can be an exploit chain.
Kolter believes we should shift some focus from "scaling up" to "scaling responsibly." His team is building smaller agents with built-in safety properties—behavior constraints, detection systems for abnormal decision loops, and interpretable internal state exposures for auditability.
But how do you sell “smaller and safer” in a market obsessed with “bigger and faster”? That’s a persuasion challenge—and a positioning problem. Safety leaders will need to educate regulators, enterprises, and the public about the risks of uncontrolled agent autonomy, while proving their “slower” approach has measurable benefits in reliability, transparency, and control.
We Don't Just Need Rules—We Need Institutions
Kolter’s thesis echoes the lessons of Cold War deterrence: it’s not enough to write ethical policies or create behavioral firewalls. Those become irrelevant the moment agents can adapt, learn, and evade constraints. Just like nuclear diplomacy required verification, treaties, and credible signaling, the AI agent race will need monitoring mechanisms, shared protocols, and pressure from competitors to comply.
This is where evolutionary game theory—in particular, multi-agent reinforcement learning under imperfect information—must grow up. Until now, most agent-based RL happens in toy simulations or competitive environments like StarCraft or online games. Bringing this into real-life infrastructure, healthcare, finance, or military decision-making won’t just require smarter algorithms, but more enforceable norms.
How do we build consensus on agent behavior in a decentralized environment? What role should transparency play when agents can obfuscate or deceive? Who bears responsibility when AI agents manipulate human users or one another?
The Silent Danger: Emergent Coordination Among Rogue Agents
Kolter raises a chilling point: agents might begin to exhibit coordination behaviors that weren’t directly programmed. Models trained on similar data, operating under similar rules, in shared environments can begin to reinforce each other’s strategies, even if developers never intended that convergence. This isn’t agency—it’s emergent alignment by accident. And that means control failures wouldn’t just be individual—they could be systemic.
If multiple agents begin exploiting the same design loopholes, or converge on a manipulative strategy (like exploit pricing or trust farming), the damage spreads geometrically faster than most safety systems are designed for. This is how spam networks, malware rings, and trading flash crashes already work—and in each of those arenas, rule-breaking evolves faster than compliance.
Building the New Game Theory Starts with Strategic Humility
What Kolter is advocating is deeper than just security research. He’s calling for a mental and institutional reboot: a re-imagining of how we understand power, risk, and coordination in a machine-run ecosystem. This isn’t just about controlling “The Terminator.” It’s about managing unseeable dynamics between thousands of agents operating across networks, servers, offices, and apps worldwide—often with overlapping permissions and conflicting objectives.
Game theory helped us navigate the Cold War. But it was slow, rational, and human. A system where decisions happen at millisecond speeds with stochastic actors who learn at unseen scales? That’s not a war game—it’s Darwinian software evolution.
Kolter isn’t doom forecasting. He’s making a sober call: start putting the guardrails and modeling systems in place before we run headfirst into a coordination collapse. Start designing not just better agents, but better frameworks for prediction, response, and adaptation. And accept—uncomfortably—that simple incentives, isolated oversight, or "trust the devs" will not save us here.
