g:vim_ai_chat vs g:vim_ai_chat_default vs default.chat roles.ini

Why is there ..._chat and .._chat_default? Why is ..._chat_default not mentioned? Why does default.chat not change the options in either of these dictionaries?

I am not sure what is the issue. The default configuration and an alternative config using default role is documented in Configuration section

I am sorry, I could not find _chat_default. If so, I'd wonder why there's _chat instead of _chat_default, but _image_default.

For example, in the mentioned https://github.com/madox2/vim-ai?tab=readme-ov-file#configuration section I read Alternatively in

let g:vim_ai_chat = {
\ "options": {
\ "initial_prompt": "",
\ },
}

Alternatively you can use special default role:

[default.chat]
options.initial_prompt =

as both settings being equivalent, but the latter was ignored whereas the former was not.

Therefore I thought g:vim_ai_chat_default
was meant instead of g:vim_ai_chat since it's also g:vim_ai_image_default and not g:vim_ai_image.
But this setting seemed to be ignored was well.

Right, there is a mistake in documentation, variables with _default postfix were never meant to be used for configuration, those are just for internal purposes, I fixed it in accbca7

There was also a bug with population of image options, fixed in 430966f

So you should be able to configure with a variable g:vim_ai_chat or a [default.chat] role. Default role takes precedence
