The simpliest usage should look like: (psuedo code)

session = create_session ( config(including model name and framework?), instruction );

request (session, prompt-string, callback-func, user-data);
wait-request (callback-func);

delete_session (session);

or

session = create_session ( config(including model name and framework?), instruction );

response = request (session, prompt-string, callback-func, user-data, sync=true);

delete_session (session);
