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; Play.ht the vendor's own pricing FAQ as captured by the Internet Archive on 20 January 2022 states words do not roll over between subscription cycles and reset each renewal, that payments already made are non-refundable, and that running out of words requires a separate one-time purchase; no dollar figures appear in this capture but the mechanism is stated plainly by the vendor
  • They diverge on capability: AI21 Labs covers Jamba models, Play.ht covers 900+ voices.
