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; Apollo.io everything is metered in credits, and the free Starter plan runs on them too, so prospecting volume is capped rather than the feature set
  • They diverge on capability: AI21 Labs covers Jamba models, Apollo.io covers Contact database.

Where each one falls short

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

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

Apollo.io

  • Everything is metered in credits, and the free Starter plan runs on them too, so prospecting volume is capped rather than the feature set
  • Plans described as unlimited are capped in the fair use policy at 10,000 credits a month for non-paying accounts
  • Connecting a mailbox that is not Gmail or Microsoft requires a paid plan
  • How many records can be selected at once varies by tier
  • Running out of credits means buying more rather than waiting for a reset
