Rumor: Anthropic's Opus 5.2 and Fable 5.2 already tested, release may slip with IPO
kimmonismus · x · 2026-09-19
Leaker kimmonismus claims Anthropic's new models are confirmed — possibly Opus 5.2 and Fable 5.2, reportedly already tested and routed internally.
The complication: releases were planned ahead of Anthropic's IPO, which has now been postponed to November. That doesn't mean new models must wait until November, but the IPO delay could push back the model release a bit.
(Unconfirmed rumor.)
