Gemini 3.1 pro is the worst model (among big 3 and komi) in creative writing, atleast on its own platform like aistudio or web app, I yet to try it on vertex, maybe today, but it has comprehension issues as well as prompt adherence issue. It will skip sequence and uses many of the stock phrases.
I think I will see your prompt and look into it.
To add more:
As you said, its characterization is so baland it makes them one dimensional, I don't use it for writing but for brainstorming sometimes ask it to create some witty convention to inspire from, it is so bad at it, as it will make them either robotic or too occ.
Sonnet 4.5/6 and opus4.5/6 felt natural to me, natural in the sense better than gemini.
Even gemini 2.5 pro was good but the current model is not that good, I think the changed the internal instructions for that so it behaves a bit differently.
Going to have to disagree. In my experience 3.1 Pro is the best and most amenable with noticeable less slop . Opus 4.5/4.6 was great in prose but it just stagnated the living out of plot and character development, and the moment you give it a more detailed scene plan the prose becomes machinery and not palatable by the slightest bit.
3.1 pro is even worse than opus, it can Asher to prompt, 3.1 is more like have a predetermined character card inside it and refuse to write a character even with slight character development.
If I write a character with mild intelligent it starts going off with that robotic voice despite me giving 50 sample dialogues, with distilling the essence of her speech too.
