Every time I use opus these days I go shut up... you are not fable.. Hard to imagine how just three days with it changed how I saw LLM use.

I really don't feel this way. Seemed pretty similar to me, noticeably better, but marginally. What am I missing?

Nothing. It had marginal gains. People just romanticize it cause it's gone.

It may depend on your specific workload. E.g. for regular webdev work Opus is more than adequate, for heavy duty data analysis, for experimental stuff and for complex systems it was night and day.

I had only a few places where I did spot a difference but that difference was significant and I can imagine where people would be amazed.

It's interesting, I tried a decent amount of "heavy duty data analysis", and found it pretty similar. But a lot of what I did was about it finding and cobbling together the right things from our existing library of domain specific tooling, which opus is already good at. But perhaps it would have impressed me more if it were starting from zero.

What kind of "experimental stuff and complex systems" did you try that it excelled at?

Yes, I've just come to the end of implementing all the planning I did while Fable was available. And nothing now comes close to creating plans that could be coded and just worked like it did.

On a large C codebase, Claude hallucinates constantly, and GPT 5.5 gets there are with a lot of help, but still gets things wrong.

I'm reluctantly starting to feel grateful that I went camping right over the window that Fable was out.

Same.
