## Our verdict

Mythos 5 succeeds the invitation-only Mythos Preview inside Project Glasswing, now sharing the exact capabilities, API surface and $10 / $50 pricing of Claude Fable 5, half the Preview's $25 / $125 list. If you held a Glasswing seat for the Preview, Mythos 5 is the upgrade; if you do not, the generally-available Fable 5 gives you the identical model.
