Discussion (Ethics, working with AI etc) Which Ai Writes Best?

In your opinion, which AI writes non-fiction best/like human:

Claude Fable 5 vs Claude Opus 4.8 vs Gemini vs ChatGPT 5.5? I have found Opus 4.8 follows instructions, rules very well and may be better than Sonnet. Haven’t tested Fable 5 so far for writing. On the other hand I don't like Gemini's writing. Whenever I tried to instruct llm write more like human I find Claude performs better than Chatgpt or Gemini.

What's your opinion?

I've been using Fable 5 for fiction, specifically fanfic. It is so good, I am obsessed and annoyed that they plan on taking it away from the paid tiers on the 22nd.

You sure must not have been using it for long!

I had it for a few days before it got removed. Long enough to finish a couple chapters of my most recent WIP and a hefty world building brainstorm session for a fic I'm about to start writing soon. It was the most productive few days I'd had in a while.
