I think it's winning on UI for normies (grok bot) and they made some claims about being pareto SOTA (lowest cost per task completed) a while back with 4.6.
I find it to be a perfectly capable model for implementation (there are many in this class--deepseek flash, spark1.3, luna, etc). I find the usage to be very generous w/ supergrok. I find the model to be just fine for 90% of what I want to do, but I use a smarter model to plan complicated things.
I'm judging on benchmarks, and whether anybody or any company I know has ever suggested using it (not yet).
I don't personally make my judgements based on how many other people mention a thing, but if that gets your code written, by all means.
The voice is the same AI slop as the others imho.
(This is about Grok 4.6, I didn't test 4.7 yet).
edit: clarified I mean agentic coding tasks
Deepswe results show that grok 4.6 is more expensive per-task and consistently scores worse than: luna xhigh, glm 5.3, astra low, sol high/xhigh, opus 5 medium.
Grok also used almost 3x as many tokens/turns to complete tasks than all of those models (besides luna), so it takes way more time to complete a task.
There isn't much reason to use Grok at all, it's gotten better but it's still worse than every other player in the field, which shouldn't be a surprise considering until about a year ago they were just buying tokens from other providers and pretending it was their own model.
With gpt-6 luna and sol coming tomorrow it's going to look even worse too, especially if new luna retains the same dirt cheap pricing that 5.6 luna has.
