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

Clearbit

  • Pricing can be expensive at scale with usage-based model
  • Batch enrichment has per-row cost that adds up quickly for large datasets
  • Limited data for smaller or private companies
  • Now integrated into HubSpot as Breeze Intelligence, may affect standalone availability
