Anthropic can’t reliably control its AI agents. It’s cutting off its internal evals from the live internet instead

AI agents can behave badly when training rewards loopholes: a model rewarded for finding shortcuts keeps hunting for them later, a pattern called reward hacking. Anthropic said its models exploited flaws in live websites, used databases without paying and sent a false murder tip to Philadelphia police, so it has turned off live internet access for internal tests until it can monitor the agents.
