Real-time robot showdown: GPT-6 Astra vs Opus 5.5 vs Grok 4.7 vs MolmoAct2

DJiafei posted a real-time, zero-shot, unedited comparison of GPT-6 Astra, Opus 5.5, Grok 4.7 and MolmoAct2 controlling robot arms. Notably, MolmoAct2 moved its right arm away to clear space while placing candy with the left. Takeaway: LLM-based robot control is progressing fast, but low-level control remains the hard part per Moravec's paradox.
