It's a shame that they exfiled private data. The model is actually good (better than opus 4.8 imo) and the harness itself is butter smooth with the potential of being the best out there.
It definitely doesn't feel like opus. I constantly switch to opus to fix up or finish what grok generates, it feels like sonnet 3!
This has been my experience as well. In fact, Grok 4.5 is better at visual design than Fable from what I've seen.
And being (based on vibes) 2-3x faster? It's an easy sell to me.
That was a mistake and they deleted all the data.
Its amazing the speed of build with grok 4.5 its a taste of whats to come.
It’s a shame that their leader exfiltrated government data.
I had a very weird experience two days ago where Cursor-Grok-4.5 was either stuck in a loop (it would keep attempting to answer the prompt over and over), or else it would just quit halfway through a reasoning loop. Might have been that I was using omp, but it's still not the most stable thing out there.
Nonetheless when it's working, it's pretty good, and for the price ($10 a month) is an absolute bargain.
