I have trained a predictive intelligence model in "Similarity" in tested that it was working fine but now it is showing "unable to predict"

Can someone tell the possible cause and its resolution.

Unable to predict” means the model executed successfully, but ServiceNow could not find a valid similarity match due to input, threshold, or data mismatch — I do NOT  think ITS  not a platform error.
 
Retrain the model if data distribution has changed (data drift)
 
Review and lower the Similarity Score Threshold if needed as If no historical record exceeds the configured similarity threshold, the model returns Unable to predict. Adjusting the threshold improves coverage when data patterns drift over time.
 
 
Hope This Helps.

I have tried retraining and decreasing the threshold to 10, is there any other way + I also wanted to know that I am triggering this model using script include and it is giving the result only if the user has admin role else not, so is there any specific role for that.
