description: CopilotKit's no-external-process agent backend — runs the agent loop in-process via the runtime, no separate framework or service required.

The Built-in Agent is the simplest agent backend CopilotKit ships. Instead of proxying to an external framework process (LangGraph, Mastra, etc.), it instantiates `BuiltInAgent({ model, tools, prompt })` inside your runtime and runs the agent loop in-process. No separate agent server, no external framework install — direct connection to OpenAI / Anthropic / Google or any AI-SDK model with full support for tools, generative UI, and shared state.

{/* TODO: Placeholder. Expand with a one-page summary suitable for the "Agents & Backends" section: when to choose BIA vs an external framework, model support matrix, what BIA does and doesn't support (no subagents, no native HITL primitive), and a link out to the full BIA docs. */}
