### Answer Based on the available sources, I don't have specific information about setting temperature on a per-node basis in Retell AI's conversation flow. The documentation shows that

model_temperature

is a property at the conversation flow level [(1) ]() , which suggests it applies globally to the entire flow rather than individual nodes . For your specific use case of wanting lower temperature for function nodes and higher temperature for conversation nodes, you might want to try the debug guide's suggestion to adjust the LLM temperature for consistency issues [(2) ]() , though this would still be a flow-level setting . I don't have documentation confirming whether per-node temperature control is available. You may want to check the [Documentation]() or contact support for clarification on this specific capability.
