Hi,
For regular NLU (not Now Assist / GenAI), the NLU model is trained inside your ServiceNow instance using the utterances and intents you define, and the training artifacts are stored locally in tables such as ml_solution and ml_model_artifact.
- The data used to train your NLU model does not leave the instance; it stays within your tenant and is not shared externally for model‑training purposes.
- There is no separate “opt‑in/opt‑out” for NLU data sharing because NLU training is instance‑local and not part of the Now Assist customer‑data‑sharing program.
The opt‑in/opt‑out controls you may see in documentation apply specifically to Now Assist / GenAI, where you can disable Now Assist or opt out of data sharing in the Now Assist Admin Console → Settings → Data sharing if you do not want your data used to improve ServiceNow’s AI models.
