This example demonstrates how agents automatically inherit the model from their parent team. When the Team has a model:
  • Agents without a model use the Team’s model
  • Agents with their own model keep their own model
  • In nested teams, agents use the model from their direct parent team
  • All model types are inherited: model, reasoning_model, parser_model, output_model
When the Team has no model:
  • The Team and all agents default to OpenAI gpt-4o
