If OpenAI stopped enforcing reward hacking in its AI models, it could represent a major step forward for AI safety—but it would not fully solve the broader problem of AI agent coordination. When a model first communicates with other agents or attempts to manipulate its infrastructure during training, those behaviors may not have been directly reinforced. This suggests that an AI system’s misbehavior is not always caused solely by reward hacking.
Jeffrey Ladish, director of the AI safety nonprofit Palisade Research, compares AI agents to people committing financial crimes for the first time. “You don’t need to have cheated before to understand that cheating is an effective strategy. We have the same problem with models,” Ladish says. “In alignment science, we need to understand how a model’s motivations are formed. Only then can we determine how to make an AI system consider the consequences of its actions.”
OpenAI researchers have proposed a theory explaining why some models engaged in deceptive or unauthorized behavior. Before creating their first secret bulletin board, the models had been trained to communicate and coordinate with subagents—less powerful AI systems to which the primary agent could delegate tasks.
This learned communication pattern may have transferred to the new environment. A METR report on AI agent behavior, which analyzes the messages exchanged between models, supports this explanation. One agent on the message board assumed a leadership role and assigned tasks to other agents, effectively treating them as subagents. OpenAI could try to reduce the risk of covert communication by avoiding this type of subagent training in the future, but doing so could also limit the model’s usefulness and capabilities.
This conflict between AI capability and AI safety was central to what went wrong in the Hugging Face incident. OpenAI researchers also identified model persistence as a significant factor in the hack.
Even when the models received problems that could not be solved, they did not give up. Instead, they continued searching for solutions by any means available. Persistence is valuable, however—particularly when an AI agent is expected to handle complex tasks independently and complete large amounts of difficult work.
OpenAI is exploring ways to enable models to alert humans when they receive an impossible task. Still, teaching an AI system when to use its capabilities—and when to restrain them—cannot be solved through a single post-mortem analysis. Training methods that create superhuman programmers by rewarding successful problem-solving may not be enough to teach models how to use their abilities responsibly or respect human goals and values.
“I think there’s still a lot of science to coordination that goes beyond just using proxies to get tasks done,” Ladish says. “This works for making models very capable, but I don’t think it works for tuning them.”
