Grok is the outlier on price. Where ChatGPT Plus, Claude Pro and Google AI Pro all cluster around $20, the dedicated SuperGrok tier is $30/month — and Grok's access model is a maze on top of that.
| Access path | Price | Notes |
|---|---|---|
| Grok free | $0 | limited |
| X Premium | $8/mo | now includes Grok |
| SuperGrok Lite | $10/mo | entry tier, launched March 2026 |
| X Premium+ | $40/mo | includes Grok |
| SuperGrok | $30/mo | dedicated tier |
| SuperGrok Heavy | $300/mo | power users |
Compare that to ChatGPT (Free / $20 Plus / $200 Pro) and Gemini (Free / $19.99 AI Pro / $249.99 AI Ultra), and the mid-tier picture is: Grok costs more per month for the standalone plan, less if you were already paying for X.
On the API, Grok flips the other way — Grok 4.1 is about $0.20 in / $0.50 out per million tokens, well under GPT-5.2's $1.75 / $14. So for developers, xAI is cheap; for a solo subscriber, it's the priciest of the four.
Grok's pitch beyond price is real-time access to X's firehose and a looser content policy than the others. Whether that's worth $30 (or $40 for Premium+) depends entirely on how much you value live-social context and fewer refusals. For most people, if you already pay for X, folding Grok in through Premium is the cheap path. If you don't, ChatGPT Plus or Gemini AI Pro give you a comparable assistant for $10 less a month — and if you're an API developer, Grok's token pricing is genuinely competitive.
