The short version

  • Each has a real cost: AI21 Labs the free allowance is $10 of credit lasting 7 days rather than an ongoing free tier; Humanloop the free plan caps at 2 members, 50 eval runs, and 10,000 logs per month; every tier above that requires contacting sales, with no self-serve paid plan published, as of August 2026.
