The GPT-5.6 Sol(max) model has achieved a new leading score on the CritPt physics problem benchmark, a private research-level evaluation developed by Argonne and UIUC. This benchmark assesses models on graduate-level physics research problems posed by over 60 researchers from more than 30 institutions, highlighting advanced scientific reasoning capabilities. Additionally, details have emerged regarding the reasoning-effort settings for the GPT-5.6 series, with GPT-5.6-Sol defaulting to a 'low' setting while 'terra' and 'luna' are set to 'medium', though the reason for Sol's lower setting remains unclear. User experience with GPT-5.6 also suggests that real-world performance and subjective evaluation are crucial, going beyond raw benchmark figures. AI
