We can switch in a heartbeat to a competitor, what kept us to Claude was that it had better models for a while. Closing Fable off means they are squarely inferior now.
For me Opus 4.8 was a slow model with a strong habit of talking down to me in an obnoxious way that would not be possible to prompt away. GPT 5.5 is now my main driver for serious work.
I’m still rattled by all the DoD stuff in the spring. At which point I deleted my ChatGPT/OpenAI account.
But Anthropic’s games with Fable and false humility is getting a bit old. And increasingly it seems like Agent Orange is gonna implode rather than team up with someone like Sam Altman to form America’s Third Reich. Particularly post-midterms.
Nonetheless, wish there was a third option on par with them two. Maybe there is I need to investigate.

In my experience, all Anthropic models tend to produce hard-to-understand word soup. They're like the kind of person who likes to use fancy words just to show you how much smarter they are.
That doesn't mean those models are stupid or just pretending. I do think that Fable is the best we can get right now. Nevertheless, I prefer OpenAI models for easier tasks where the primary output is text and explanations, not code.
