So I logged into the Claude Code and their fabled Fable 5 model is "not available". Because it's "so good" and "so dangerous" that I can't have it.
Judging by the amount of bugs in CC, this model can't be all that good.
But regardless, what is the point of paying to Anthropic if their models are not available to you? I am switching to GPT 5.5.
It's good. My brief exposure to it suggests it deserved a new product name.
I got to use it for a couple of days on Pro. Feature implementation actually fit into subscription usage, but then it went on chasing its tail fixing bugs it introduced and burning through about $15 in credits. It got the job done in the end, though. I'd say it's good, better than Opus, but I found that both GPT 5.4 and 5.5 are way better than Opus.
So Fable is as good as GPT 5.5, if not better.
