There are some point which concern me.
I think your project need have huge DB because of using AI.
Then,it seems to be difficult for me merely storing on chain.
i would like to you tell me

- the amount of data you are assuming
- how to save them
Thank you very much for your question.

The data for AI models is not within the scope of our product. Any external developers who want to create their own AI models would need to get the data themselves. (But we will definitely help guide!)
As such we do not need a huge database for the marketplace.
