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.
