I'm a huge fan of Mathematica; I've been a subscriber for many years. There's much to love about the product, but its AI assistant isn't among them.
Claude Caude is much better at Mathematica than Wolfram's own AI assistant. I think they flat-out acknowledge the very limited abilities of Mathematica's AI assistant in this version 15 announcement.
The Wolfram AI assistant is so bad I unsubscribed from it. By the sounds of it, a basic AI assistant is offered included with subscriptions now. I feel it's borderline criminal they were charging for their hallucinatory AI assistant in the past.
Honestly I've found even Gemini Flash is better than Wolfram assistant...
But that's fine. Mathematica client supports openrouter as LLM provider anyway so we can use whatever we want.
