Ask HW: Best frontier AI model for mind map generation?

For my children, I need to generate mindmaps from image taken from books.

I want to use a frontier model (i.e. Claude, Mistral, ChatGPT, Grok...) but I want the most effective in terms of cost and quality.

I was not impressed so much by Mapify or NotebookLM.

Do you have some skills / suggestions / successful stories to share?
