I use both Grok 4.5 and Opus 5. They’re both very good and Grok is faster and cheaper.

Opus 5 is terrible. I'd even say it's a step backwards from 4.8. I'm getting high error rates from it, and then it catches the error, and then it sometimes errors the error fix (!).

Just today I had to switch another agent to Fable with the instruction, "Please clean up the mess that Opus 5 made, thanks"

The other day, Sol called Opus 5's handoff (a skill I have that is basically a compaction, but just written to a file not tied to one LLM) "incoherent", that was a new one.

Opus 4.8 or Fable (at great expense) are the only ones that aren't frustrating for me.
