The object form also accepts `speed`, `effort`, and `inference_geo` fields; see the tips under [Create an agent](https://platform.claude.com/docs/en/managed-agents/agent-setup#create-an-agent), [Effort levels](https://platform.claude.com/docs/en/build-with-claude/effort#effort-levels), and [Pin the inference geo](https://platform.claude.com/docs/en/managed-agents/agent-setup#pin-the-inference-geo). |

 You can also override `model`, `system`, `tools`, `mcp_servers`, and `skills` for a single session without changing the agent. An `effort` level set inside a per-session `model` override isn't applied, and because the override replaces the agent's `model` object in full, a session created with a `model` override runs at the model's default effort level; to run at a specific effort level, set `effort` on the agent and don't override `model` for that session. See [Override agent configuration for a session](https://platform.claude.com/docs/en/managed-agents/sessions#override-agent-configuration-for-a-session).
