Charm supports three execution lifecycles. Choose the lifecycle that matches how your agent should behave for users.

Comparison

​
Serverless

Serverless is the default lifecycle. Use it for tasks that can complete within a bounded execution window. Examples:
  • summarize a document,
  • generate a report,
  • transform data,
  • call external APIs.

​
Interactive

Interactive agents stream responses back to the user and work well for conversational interfaces. Use this for:
  • chat agents,
  • multi-turn assistants,
  • agents that need immediate UI feedback.

​
Daemon

Daemon agents run as long-lived machines. Use them when the agent needs to keep running after the initial request. Use this for:
  • Slack or Discord bots,
  • monitors,
  • scheduled or event-driven agents,
  • persistent background workflows.

​
Choosing a Mode

Start with serverless unless you specifically need streaming or always-on behavior. Move to interactive for chat UX and to daemon for background processes.
