The short version

  • Each has a real cost: Replicate private model deployments are billed for all the time instances are online, including setup and idle time, not only for processing; Vellum pricing varies significantly by computational tier, making budget planning difficult
  • They diverge on capability: Replicate covers Model hosting, Vellum covers Persistent AI identity.
  • Prices and features above were last checked on 30 August 2026.
