The problem with Grok 4.7 is that it's not amazing at anything, and didn't even retain the blazing fast performance of Grok 4.5 which made it awesome for highly interactive workflows.

But despite all the negative coverage, I can say with confidence that Grok 4.7 is a great code reviewer. You know who says that? Every other model. A lot of my time is spent orchestrating code reviews. I will give the same prompt to three models, then give each model the responses from the other two models to assess and rank them. Finally I give the rankings and meta-rankings to Opus to synthesise a final report.

Right now, for the code I'm dealing with (embedded c++, python, swift, and CFML) I'm fairly consistently seeing every other model rate Opus 5.5 first, with Grok 4.7 a very close second, often finding real issues other models miss.
