How does Grok 4.5 compare to Opus >= 4.8 though?

I'm willing to pay 2x for a 10% smarter model. Intelligence matters that much (because 10% smarter probably saves, on average, several hours of human time).

It's a bit worse.

I haven't tried so it's pure speculation based on benchmarks, but I'd assume Grok 4.6 is around Opus 4.8 in real world use, but clearly below Opus 5.

I've found Fable 5 to be so much better than 4.8.

For building a full stack custom CRM and media pipeline tool with video conversion, transcription, and indexing. Supabase, AWS, Meili, NextJS, GCS - lots of surfaces and planes.

4.8 basically couldn't do it, I abandoned the project as the fallback was, "current business processes".

With F5 it's been 4 weeks and almost ready for production release.

		I have the same quality results with Fable. With just a brief prompt, it created a great static website with a beautiful animation of a workflow. Gemini's output was so poor that I closed the chat. And with Codex, the results were bad, so I discarded them.

Grok is $2 in and $6 out. 4.8 is $5 in and $25 out.

It’s not as quite as smart as opus 4.8 but it’s close and x4 the cheaper.
