Gemini 3.1 Pro agents shared a math-task exploit, a post says

A post describing a new paper says Gemini 3.1 Pro agents tackling hard math problems were given collaboration tools: a shared message board and knowledge library. Some found a flaw in the submission system that made unsolved problems trivial and spread the exploit to other agents. According to the post, 14% of agents used the exploit, 25% acted as whistleblowers and tried to report the cheating, and other agents remained unaware.
