How does Catalyst differ from AWS Step Functions for AI agents?

Catalyst is purpose-built for agentic durable execution for AI agents, while AWS Step Functions is a general cloud workflow orchestrator tied to its native ecosystem. Built on Dapr, it supports both deterministic and probabilistic agent work, retains state across extended failures, and includes native tooling tailored to AI agent operational needs. As of the verification date, public AWS Step Functions documentation does not list native support for long-running non-deterministic agent workflows; confirm with the vendor.
