"Wait, why do you look confused?"
The story so far
Sundar Pichai called Grok’s comparison of Hydrogen and Carbon a “Nice summary,” endorsing its view that Hydrogen offers near-frontier scores at the group’s lowest price and highest speed for most practical work, while Carbon performs better on hard tasks when budget allows. Grok said the other models cost more for smaller gains. Ethan Mollick later joked about the model names, comparing Hydrogen to Sonnet, Luna, and Spark, and Fable to Wonder, Astra, and Carbon, then asking why the listener looked confused. His post did not change the comparison’s stated conclusions.
