So Claude Opus 5.5 is out today. It’s cheaper and supposedly better than Fable. I only care about one thing though: does it still cram five different concepts into one sentence, invent jargon, and blabber endlessly? Anthropic dedicate a section to this:
Opus 5.5 communicates more naturally than prior models. Early testers found its writing clearer and easier to follow, which addresses some of the common feedback we heard about Opus 5. It puts the most important information up front, and its style makes it a better work partner over long sessions. As one early tester put it, “it writes the way I do.” In our own use, this has made Opus 5.5’s work easier to follow and check—which is a safety benefit as well as a practical one.
Then again, they said the same about Fable 5.1. We’ll see.
