The short version

  • Only H2O.ai 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; H2O.ai java is always required to run H2O-3 even when working from R or Python, and only a 64-bit JRE or JDK is supported
  • 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

H2O.ai

  • Java is always required to run H2O-3 even when working from R or Python, and only a 64-bit JRE or JDK is supported
  • Supported Java versions stop at Java SE 17; newer versions only run by forcing an unsupported version flag and are guaranteed for experiments rather than production
  • H2O-3 only supports numpy below version 2, so a numpy 2 environment must be downgraded
  • Supported Python versions are limited to 3.7 through 3.11
  • The Flow web UI requires an internet browser and is the only graphical interface
