 # Structured tool chat
 
+:::info
+If you are using a functions-capable model like ChatOpenAI, we currently recommend that you use the [OpenAI Functions agent](/docs/modules/agents/agent_types/openai_functions_agent)
+for more complex tool calling.
+:::
+
 The structured tool chat agent is capable of using multi-input tools.
 
 Older agents are configured to specify an action input as a single string, but this agent can use the provided tools' `args_schema` to populate the action input.
