This started back in February and looking at commits, Fable did only a small part of the latest commits. 19 commits out of 2000:

And maybe it wasn't even Fable, they might have downgraded to Opus.
This is the kind of frequent misinformation that makes me skeptical of Anthropic LLM claims. Whenever I compare them to GPT 5.5 on my web dev workflows, they seem to trade blows, even Fable, which I started testing since it was re-enabled.
Also I bet any decent LLM could have done such port. Think GLM 5.2 or similar which would probably work better because it doesn't constantly try to guess if I'm a terrorist trying to hack goverments or develop some biological weapon.
People just don't have the resources to compare LLMs and imply whatever they used is the best thing ever and unlocked some new workflow.
I have seen little improvement since Opus 4.6.
