The short version

  • Only Modal 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; Modal the Team plan carries a $250 monthly base fee and returns only $100 of that as free credits, so $150 is a flat charge before any compute
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Grok

  • Pricing is not published; all access requires sales contact or account negotiation
  • Limited ecosystem compared to OpenAI and Anthropic; fewer third-party integrations
  • Organisational reputation tied to Elon Musk; policy or direction changes may affect service continuity

Modal

  • The Team plan carries a $250 monthly base fee and returns only $100 of that as free credits, so $150 is a flat charge before any compute
  • Compute is billed per second across separate GPU and CPU meters, so total cost depends on execution time rather than any fixed rate
  • The Starter plan's $30 monthly free credit is the only allowance below the paid base fee
  • Enterprise volume discounts are custom and unpublished
