The short version

  • Only Pi has a free tier, so it costs nothing to try first.
  • Each has a real cost: Grok pricing is not published; all access requires sales contact or account negotiation; Pi inflection AI's own homepage (2024 archive) pivoted its headline positioning to enterprise AI licensing rather than the consumer Pi assistant, with no consumer pricing or plans published on the corporate site
