The short version

  • Each has a real cost: 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; Runway the free tier is 125 one-time credits rather than a monthly allowance, so it runs out and does not refill
  • They diverge on capability: Pi covers Conversational AI, Runway covers Gen-2 video generation.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

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
  • Requires iOS 16 or later, per the App Store listing

Runway

  • The free tier is 125 one-time credits rather than a monthly allowance, so it runs out and does not refill
  • Outputs carry a watermark until the Standard plan at $12 a month
  • Everything is metered in credits, and Gen-4.5 video costs 60 credits per 5 seconds, so a Standard plan covers roughly 125 short videos a year
  • Only the Max plan at $76 a month rolls unused credits over, and only for one month
  • The free tier gives a selection of models rather than the full set
