haider1 · x · 2026-07-19
A post claims that **GPT-5.6 Sol** was given to external testers two months ago, around the same time the public received **5.5**. The author mentions that the ARC-AGI team stated they had access for **4 times** longer than OpenAI's usual release window, hinting that much of this chaos might stem from the **US government**. Finally, they contrast this by noting that "Kimi K3 might be released before 5.6."
