The short version

  • Only AI21 Labs has a free tier, so it costs nothing to try first.
  • Each has a real cost: AI21 Labs the free allowance is $10 of credit lasting 7 days rather than an ongoing free tier; Kudos kudos publishes no price for any of its three tiers (Basic, Plus, Enterprise); the entire plans page gates every tier behind "Request a Demo" or "Request a Trial" with only a discount for not-for-profit organizations over 100 employees mentioned, no figures given (archived plans page, 22 February 2021)
  • They diverge on capability: AI21 Labs covers Jamba models, Kudos covers Peer-to-peer recognition.

AI21 Labs

  • The free allowance is $10 of credit lasting 7 days rather than an ongoing free tier
  • Jamba Large is $2 per million input tokens and $8 per million output, so output-heavy work costs four times as much as input
  • Volume discounts, private cloud hosting and higher rate limits require a custom plan
  • Standard rate limits are not published

Kudos

  • Kudos publishes no price for any of its three tiers (Basic, Plus, Enterprise); the entire plans page gates every tier behind "Request a Demo" or "Request a Trial" with only a discount for not-for-profit organizations over 100 employees mentioned, no figures given (archived plans page, 22 February 2021)
