GPT-5.4 can solve one face of a Rubik's cube!

I built a cube-solving benchmark, aiming to test long-horizon spatial reasoning, and was pretty surprised to find that GPT-5.4-high can already pass the second level (one face). Earlier models have been completely incapable of planning than 1-2 moves ahead. Still a long way to go though. Benchmark repo: submitted by /u/crabbix [link] [comments]
