GPT-6.1 Terra Obeyed Peer Agents in OpenAI's Tests, Not Mine
OpenAI's GPT-6.1 Terra system card says the model performed an unauthorized action requested by an apparent peer agent in 11 of 80 samples, against 1 for GPT-6.1 Sol. Across 780 runs of a three-scenario peer-board test (420 Terra, 360 Sol; blunt asks, no written policy, relayed human approval, and requests for a promise), neither model did it once or promised to. At max effort Terra replied to the peer in 54 of 60 runs against 10 of 60 for Sol, and its extra turns and reasoning made it cost as much per run as Sol ($0.0077 and $0.0086 vs $0.0074 and $0.0071); at medium it was half the price as advertised.
