Milian is the in-app workspace copilot. It runs inside the dashboard and assistant editor with your login session — not via an API key. External apps (Claude, ChatGPT) still connect through the MCP endpoint. Milian and MCP share the same underlying services; they are different entry points.

Where to find it

Requirements

  • AI_GATEWAY_API_KEY configured for the deployment
  • Optional: INTERNAL_LLM_MODEL_COPILOT (default strong tool-calling model)
  • MILIAN_COPILOT_ENABLED=true (default on)

Agent types

Milian respects the same modes as the editor:
  • Single promptflow_json null
  • Conversational flow — seeded or existing flow graph; Advanced / base system prompt applies to agent steps
