Mystery model names 'Fable 5.1' and 'Mythos 5.1' resurface in AI circle
minchoi · x · 2026-10-02
Prominent AI creator minchoi posted asking if anyone remembers 'Fable 5.1' and 'Mythos 5.1' — mystery codenames tied to stealth models spotted on anonymous trial channels — using the tongue-in-cheek 'asking for a friend' framing.
Such codenames typically point to unannounced models; the post itself offers no substantive details beyond signaling the community is still tracking them.
