I disagree. When I got Fable to engage with research questions before they tightened the guardrails it was a genuine step up from Opus 4.8. I see no real reason that what everybody reported isn't exactly what happened.

With these guardrails it is completely useless. The only hope is that they eventually convince the US Gov to let them use a saner classifier.

I had the same. Just before Fable became available, I was working on a document building on a ton of research that I wasn't entirely sure about (I don't think it counts as research itself, except in the Facebook sense). I had Opus and Gemini review it a couple of times until they and I thought it looked pretty good. Then Fable appeared, I had it review it, and it still found a ton of errors.

It's definitely good. Or at least it was. I'm not sure how badly they nerfed it.
