Moving to riyadh

Is 9000 riyal per month offer with accomodation,medical insurance and flights tickets is worth to take for a Senior Artificial intelligence Engineer / Data Scientist?
Providing that i am supposed to write a bond for 18 months.

No, it is very low. I can say this because I am a senior architect in an IT company. If you plan to bring your family here and have kids going to school, you will struggle a lot. You can PM me if you want to discuss further
