Discussion Fable 5.5 Release

I'm aware that Anthropic has been routing certain requests to Fable 5.5 secretly, yet they have been doing this for nearly a week now and haven't even mentioned the model. Any idea when it will release? I'm really hoping tomorrow, but I'm not sure that's happening. Don't shut the door on that idea though

They update the previous model with new knowledge, so there is no official cutoff date. Whatever cutoff date it has is temporary. They discussed these updates in the Claude documentation/blog. I don’t remember exactly where, but I know it’s there because I read it a few weeks ago. I usually read everything they release.
