Is it even possible or are we just dreaming about next Fable

Astra represents the first significant competition for Anthropic, which is rumored to have internal models like "Model 2" and potentially Mythos, developed since April. There's speculation about whether Anthropic will release a new model, possibly Fable 5.2, before its IPO, or if Fable 5.1 is merely a placeholder. It seems unlikely a full new Fable will be released soon, given the impending IPO, but internal development of next-generation models is common practice.

This discussion uniquely speculates on Anthropic's internal model development, like "Model 2" and Mythos, and whether a new Fable version will launch before its IPO, unlike other reports.
