As I understand, the code part is in https://github.com/Tiger3807861189/J-Space-Cognition-Suite-V... but there's nothing there that would make V4 Pro perform as well as Fable, it's mostly prompting - that's not even a proper implementation of "J-Space".
The repo gave you guide and benchmark of how to tweak ds4 pro for better performance, with a clickbait title (Fable 5 level), what kind of more proof do you require? More benchmarks? Reports for media outlets? STF model on HF?
