- It's not "incrementally better". It's a complete game changer. Opus 4.8 on max thinking does X amount of mistakes in my commercial work. Fable 5 did 5% of X. Counted. I barely had anything to contribute in the work sessions, for a full week I could count on my two hands the total amount of times I actually caught Fable 5 -- and one part of those were not true mistakes, more like divergence from policy in our `CLAUDE.md` files.

- It's not "security focused". It's simply better in every way _plus_ it's also security-conscious.

- It legitimately accelerated my work. I don't have too much unknowns in my work, I simply have way too much to do. Fable 5 was an objective and measurable improvement over Opus 4.8. Returning to it after Fable 5 was removed was extremely discouraging and frustrating, and still is to some extent.

> It’s lots of fun to pretend it’s some step-change that’s too dangerous for general release

Maybe, but not as much fun as tearing down a straw man apparently. :)

> (Just to be clear, I think the gatekeeping is ridiculous, especially given the above)

It's ridiculous for multiple other reasons but ridiculous nonetheless.

Fable wasn’t available for a full week. It was released on June 9 and made unavailable June 12.
