+#### Execution a function on demand.
+This is the first message that should be sent to the AI Engine for execution the function/s of your choice.  
+The main difference in here it is the AI Engine won't search, therefore decide for you, what is the apt function to fulfill your needs.
+
+It contains the list of function-ids you want to execute and a function group (for secondary function picks).
+
+Currently only supported by Next Generation personality.
+Don't use this if you already sent 'start' message.
+
+```python
+# init the AI Engine client
+from ai_engine_sdk import AiEngine  
+ai_engine: AiEngine = AiEngine(api_key)  
+# Create (do not start) a Session
+session = await ai_engine.create_session(function_group=function_group.uuid)  
+
+# Execute function. You will receive no response.
+await session.execute_function(function_ids=[function_uuid], objective="", context="")
+
+# In order to get some feedback, gather the messages as regular.
+while True:  
+    messages: list[ApiBaseMessage] = await session.get_messages()
+    # throttling
+    sleep(3)

 #### Checking the type of the new message
 
 There are 5 different types of messages which are generated by the AI Engine and the SDK implements methods for checking the type of the respective new <code>Message</code>:
