Where each one falls short

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

ADP

  • No pricing is published; every quote is custom and driven by employee count and which services are taken
  • Split into three separate products by company size, RUN for 1 to 49 employees, Workforce Now for 50 and above, and Lyric HCM for enterprise, so growing across a threshold means changing product rather than plan

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
