Grok has a personality, a real-time view of X that nobody else has, and models that have climbed the benchmarks quickly. Grok Imagine makes images and short video, Tasks run on a schedule, and the SuperGrok plan at $30 a month gives a serious amount of all of it.
The trade is the one every single-vendor plan makes. Your $30 buys xAI's models and only xAI's models, so on the day Claude edits better or Gemini reads a spreadsheet better, you are on the outside. Your conversations are used to train Grok unless you turn it off under data controls, and the heavier tiers climb to $300 a month.
Magai includes the Grok models in every plan, next to GPT, Claude, Gemini, Perplexity, DeepSeek and dozens more, in one thread you can hand between them. It starts at $20, and nothing you write, upload or generate trains any model.
