GPT-5.6 Sol Early External Testing Leaked
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."
