  • Go at $8/mo gets you more messages, uploads and memory for well under half the price of Plus

  • Free tier includes chat, voice and real-time web and X search
  • SuperGrok adds higher limits, frontier models, and image and video generation
  • SuperGrok Plus ($100/mo) adds much higher usage and 1080p video
Catches
  • Free and Go may show ads. Plus ($20/mo) is the cheapest ad-free plan
  • No annual billing on Go, Plus or Pro, so no discount for committing
  • Most limits say 'limited' or 'expanded' rather than giving a number, so it's hard to know when you'll hit the wall
  • No published usage numbers on the pricing page. Limits are described, not counted
  • Shared usage means video and coding can eat into chat
  • SuperGrok costs $30/mo, $10 more than ChatGPT Plus or Claude Pro
