Kudos to WRI on release of Wolfram (Mathematica) Version 15.

I jumped onto the new built-in AI Assistant following along Stephen's blog.

In my trials, each trial a clean session (exit notebook and kernels), the example chat prompt "solve for the eigenmodes of a pentagonal drum" yielded varying results, not too surprising, but the second session produced failing code (syntax).

Wanting to learn more, I browsed the Documentation Center ("Help"), searching on "AI Assistant" but the top hit, tutorial/AIAssistant, yielded a confusing page mixing the pre-V15 Notebook Assistant and V15 AI Assistant. There is better overview information available: AI Assistant and AI Access.

Regarding the latter link, I wonder what is gained over the free (V15 included) "Basic" AI Access level by the paid "Pro" and "Research" levels. I'd very much appreciate an example chat session comparison between the three showing how the higher-level LLMs improve results over the Basic level.
