Claude's Mythos model Claude Fable 5 and Claude Mythos 5 From today through June 22, Fable 5 is included on Pro, Max, Team, and seat-based Enterprise plans at no extra cost. It was just released It'll take a few more tests, but so far it does seem like a huge step up, which is really exciting. Here's a quick side by side. Fable Opus From today through June 22, Fable 5 is included on Pro, Max, Team, and seat-based Enterprise plans at no extra cost. On June 23, we'll remove Fable 5 from those plans. Using it after that will require usage credits. If capacity allows, we'll extend the included window. After this point—when sufficient capacity allows us to do so—we aim to restore Fable 5 as a standard part of subscription plans. We intend to do this as quickly as we can.
