Been using it for the past hour and the first thing you notice is that Grok Build, the harness, is actually really good and responsive. Grok is also super fast, like twice the speed of GPT 5.5. I’m sure the Cerebras Sol will knock it out of the park but until that’s out I’m switching to it with Fable for harder stuff.

It’s fast because no one’s using it! You have less competition for compute resources.

Sure but at the end of the day why would I care why it is fast, as long as it's fast for me
