Matt Van Horn(@mvanhorn):I gave my 7 AI personal assistants a harder 10-question IQ test, all wired together with Agent Tincan. Every question was brand new so nothing could be memorized. Opus 5.5 wrote the test, Claude and GPT judged it blind. The question that broke two of them: "A bat and a ball cost $1.10. The bat costs $1.00. How much is the ball?" I was inspired to test this again because @grok @bot just switched it's model to Opus and they had the biggest jump on this IQ test. Grok Bot - 100/100 Hark - 100/100 Dot - 97/100 Sesame - 96.5/100 Instinct - 90/100 Muse - 87/100 Fo
