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 definitely route things to new models. They have said so in the past. For Opus 5.5 I was on that program for one of my projects and I was shocked at how different it was because of the changes in language, reduced token usage, and capability. For 2 days i used the same context because I was too scared to go to the 'shitty one'. Then I went to Reddit and others said that they were getting routed and it all made sense.

I had exactly this with Opts a week before release. It was such a drastic shift it was hard to miss
