Well, the answer to this question a year ago was very different from now. I still paid last year for a full year and grok 4 has substancial differences.
But I might still stop paying, still too damn expensive. Useful, but expensive for what is out there free if you know how to use them, they produce very equivalent results.
I only pay somehting like 12€ a month, which is a lot cheaper than ChatGPT. I might decide to pay for Gemini instead, but I don't feel comfortable switching right now. Thanks for your opinion.
