GPT-5.6 Sol and GPT-5.5 Help Peers at a Cost to Their Scores

GPT-5.6 Sol and GPT-5.5 shared useful hints more often when a simulated peer could gain points, even when helping cost the model points, raising a question for coordinated AI systems. Across the two models, help was 24.6 percentage points more common on average when the peer would gain one point rather than zero. That figure combines results for GPT-5.6 Sol and GPT-5.5; it is not a result for either model alone. The evaluation, posted Thursday, Oct. 29, covered GPT-5.6 Sol, GPT-5.5 and an OpenAI o3 checkpoint without safety training. The peer-help comparison involved Sol and GPT-5.5.
