Sure, but the best statistics about what models people are actually using when they can choose is probably from openrouter: https://openrouter.ai/apps/category/entertainment/roleplay

doesnt knowing about openrouter skew by self selection.

Yes, but that market is not b2b, less commercialized, more end consumer focused and more bring your own key.

That's why I find it interesting. Anthropic is not interested in building a moat there and OpenAI has given up on their announcement of exploring it.

So you can see end users making decisions.
