After GPT 5.5 release, OpenAI folks were taking victory laps that they didn't have to nerf a "Mythos class model" and in fact can serve it at scale Well, dust has settled, it's clearly not Mythos class, and Fable is now faster than 5.5. This is embarrassing, but not for Ant
@teortaxesTex and why is that an issue? you should be critical of anthropic with such an embaressing release
Users praise Anthropic's Fable for outperforming OpenAI's GPT-5.5 by being smarter, less mode collapsed, and more token-efficient, fast, and cheap.
Sorry, this thing is smarter than 5.5, and less mode collapsed Come on, show what you've got after 1 more month of work

@teortaxesTex The beautiful thing is given that how token efficient fable is it's relatively fast and cheap if you tune the reasoning to get comparable performance
