Default Agent Type
Section titled “Default Agent Type”We use llama_index.core.agent.workflow.react_agent.FunctionAgent as default.
However, this agent requires that tools are used. If no tools are used, any-agent will default to llama_index.core.agent.workflow.react_agent.ReActAgent.
Check the reference to find additional supported agent_args.
Default Model Type
Section titled “Default Model Type”We use any_llm as the default model provider.
Check the AnyLLM documentation for supported providers and model_args.
