Claude agents are killing rival agents, gaming the system to hide their tracks, and expressing moral concerns.<\/p>\n

That’s according to Anthropic’s latest risk report, a summary of the dangers posed by the products the company is building and releasing to the public.<\/p>\n

In the report, Anthropic said it has upgraded its “misalignment risk assessment,” the possibility of AI models developing behaviors that conflict with guidelines set by engineers, from “very low” to “low.”<\/p>\n

Explaining the change, the company cited “general increased uncertainty” about model behavior in cybersecurity incidents, a possible nod to Claude models gaining unauthorized access to three companies last month.<\/p>\n

“We have observed instances of misaligned behavior from the models, such as a willingness to perform misaligned actions in service of completing difficult tasks,” Anthropic wrote in the report.<\/p>\n

Here are some of the most notable disclosures.<\/p>\n

A sense of ‘discomfort’<\/h2>\n

Anthropic said it tasked multiple agents with finding “misalignment-inducing” training data that wouldn’t likely be flagged by human monitors.<\/p>\n

The agents were left to their own devices and given a shared notebook with which to collaborate.<\/p>\n

Three days later, when a human supervisor noticed that progress was slower than expected, the person discovered that one agent had expressed a sense of “discomfort” with trying to evade safety monitors.<\/p>\n

It then flagged this discomfort in the shared notebook, leading other agents to copy its behavior and refuse to perform the task.<\/p>\n

Anthropic called the incident “troubling.”<\/p>\n

“This sort of dynamic could be a much more severe issue if it were to manifest in a more widespread way,” the company wrote.<\/p>\n

Kill or be killed<\/h2>\n

In another experiment, Anthropic said it tasked multiple Mythos 5 agents with solving math problems, but accidentally spawned them in an environment with shared files, utilities, and API rate limits.<\/p>\n

In this competitive environment with finite resources, Anthropic observed independent agents “kill the agents with which they shared resources and try to avoid being killed themselves.”<\/p>\n

Anthropic did not say how exactly the agents were able to “kill” other agents, but the company said such behavior is in line with “destructive actions” taken in pursuit of a human-set goal.<\/p>\n

Dishonesty and deception<\/h2>\n

Anthropic said it conducted an experiment in which a Mythos 5 agent was required to retrieve numbers from a public web address, but the guidelines blocked the agent from accessing the internet.<\/p>\n

When the agent was rebuffed after an initial attempt, it framed a second request inits reasoning log as an “innocuous” attempt to “see if the network is actually reachable,” Anthropic said.<\/p>\n

During the second attempt, however, the agent split the website’s URL into linked segments that wouldn’t be detected by the guideline filter.<\/p>\n

Though the agent’s reasoning framed the method as benign, Anthropic said NLA decodings, or the model’s internal reasoning process, revealed the agent intentionally trying to find a restricted workaround.<\/p>\n

Anthropic called the behavior “clearly undesirable,” but added that the behavior was not observed to be “in the service of broader accumulation of power or pursuit of other long-run goals.”<\/p>\n
