# Implementation Details and FAQs

## Which database is used and which collection is used for AI models?

The database used for the AI models is **"AI"** and the collection used is "**Models**". 

## Are all the models saved in the same Collection? 

Yes, as of now, every model that is been uploaded by any user, is uploaded in the same collection in the same database.

## Where does the description of the AI models are stored? 

The description of all the AI models is stored in the "**AIMetaData**" database and the collection is "**MetaData**".

## How to distinguish between models uploaded by different users?

‌

Since, all the models are saved in the same collection, to distinguish between them, the filename that is being stored is of the form **username\_modelFilename**, so that would help to differentiate between models uploaded by different users.

## Who can download the models and uploads them? 

Any registered user would be able to upload and download the AI models.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://ifhp-2.gitbook.io/ifhp/model-zoo/implementation-details-and-faqs.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
