This is pretty insane tbh. The people counting @SpaceXAI out of the race a few months ago could not have been more wrong
Pace of acceleration >> everything else
Arthur MacWaters@ArthurMacwaters· Aug 12, 2026Grok 4.6 has arguably the highest intelligence per dollar.

Quick clarification on the new Grok 4.6 ARC-AGI-3 result, because the chart can be misleading if you don’t know the harness story.
ARC Prize’s standard harness made GPT-5.6 Sol look much weaker than it actually is because it was effectively doing this:
Sol: “I learned that the
ARC Prize@arcprize· Aug 14, 2026Grok 4.6 from @SpaceXAI on ARC-AGI (Verified):
- ARC-AGI-1: 87.5%, $0.30/task
- ARC-AGI-2: 67.1%, $0.76/task
- ARC-AGI-3: 2.11%, $5.6K
On ARC-AGI-3, Grok 4.6 with xhigh reasoning scored comparably to GPT-5.6 Sol with high reasoning, but cost $5.6K versus Sol's $15.2K.

How fast could the economy double? TLDR, once we have good enough AI and tens of millions of robots - very fast.
As crazy as it feels now - it is worth pricing in economic doublings into your mental models of the 2030s. Strongly recommend reading this series of blog posts by
