Grok vs ChatGPT: prices, the Super plan (formerly SuperGrok) and privacy

Grok or ChatGPT: plans and prices, what happened to SuperGrok, API rates and whether they train on your chats, with official sources and check dates.

By Cognenza editorial team · Updated · Euro prices as published for Spain; they may differ in your country.

Verdict

ChatGPT has the clearer free version; Grok is worth it if you already use X or want its API.

Main differences

  • Currency: Grok charges in dollars, VAT not included; ChatGPT shows euros in Spain.
  • Free plan: xAI does not publish its exact limit.
  • API: Grok 4.7 costs USD 2.00 input and USD 6.00 output per million tokens (prompts under 200K); GPT-6.1 Sol, USD 2.00 and USD 10.00.
  • API context: 500K on Grok 4.7 and 1,050,000 on GPT-6.1 Sol.
  • “SuperGrok” no longer appears on the pricing page: the plan is now called Super (USD 100 per month).
