Scoop: Anthropic reportedly prepping fresh Fable-class pretrain to launch before September IPO
teortaxesTex · x · 2026-09-09
Unverified scoop from account synthwavedd: Anthropic plans to launch a successor to Fable 5.1 before its late-September IPO, potentially slipping to early October. It would reportedly be Anthropic's first fresh pretrain for the Fable class, with the team confident it will dethrone Astra; insiders reportedly see Astra as impressive but not sleep-loss-inducing.
Replying, teortaxesTex notes OpenAI will also be further ahead by early October and frames the move as saving face before the IPO.
Caveat: this comes from an anonymous leak account and is not officially confirmed by Anthropic.
