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

Otter.ai

  • Two separate limits apply at once, a monthly minute allowance and a per conversation cap, so a long meeting can be cut short with allowance remaining
  • The free plan cuts off at 30 minutes per conversation and 300 minutes a month
  • The Pro plan still caps a single conversation at 90 minutes
  • Even unlimited plans cap a conversation at 4 hours
  • Imported file transcription has its own separate monthly limit, at 6,000 minutes on Business
  • Paying monthly rather than annually roughly doubles the rate, from $8.33 to $16.99 on Pro
