Agent Runtime
The execution environment that runs AI agents, managing the loop of observation, reasoning, and action along with tool execution, memory, and error handling.
In Depth
The agent runtime is the infrastructure that brings an agent to life. It manages the core agent loop: send context to the LLM, parse the response, execute any tool calls, collect results, and loop back. Beyond this basic loop, a production runtime handles: concurrent agent execution, timeout and retry logic, memory management, cost tracking, rate limiting, and graceful degradation. The runtime is what makes the difference between a prototype agent running in a notebook and a production agent serving thousands of requests.
