Where each one falls short

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

Letta

  • The Developer API plan charges $0.10 per active agent per month plus $0.00015 per second of tool execution on top of a $20 per month base and pay-as-you-go LLM usage, as of August 2026.

Paragon

  • No price is published for either plan, and both require a quote
  • Cost scales with the number of customer tenants using the integrations, so the bill follows an end customer count rather than the vendor's own usage
  • SAML SSO, self hosting, dynamic field mapping and SLAs are all Enterprise only
