Need inputs on license usage

I am planning to deploy dify open source platform in one of my client organisation, and the client is planning to use it as a internal platform tool within their organisation where all the users are belonging to the organisation but they are from different teams.

As per the license terms is this a single tenant or multi tenant? and if considered as a multi tenant, does anybody have licensing cost for these kind of self hosted cases?
