I Designed the AI Agent as a Runtime from Day One, Not as a Chat with Functions

The author designed an AI agent as a runtime from day one, not as a chat with functions. This approach allows the agent to take action and carry tasks beyond a single message. The key difference is that the task can live longer than one message, enabling the agent to perform complex tasks and workflows. This is in contrast to traditional AI chats that only respond to a single request. The author's approach is necessary for a real agent to perform tasks such as setting reminders, searching, and making plans.
