neuraptic/nexusml — reverse-engineered prompt

Build me a Python based multimodal AutoML platform called NexusML. I want it to let people create classification and regression projects with as little manual setup as possible, upload and manage different kinds of data, train models, and work with results through a clean API and developer friendly package.

It should support multiple organizations, where each tenant has its own isolated workspace and members can collaborate without affecting anyone else. Use Auth0 for sign in and organization aware access, and support AWS S3 as a file storage option when it is configured. I also want subscription plan support so each organization can have limits for things like storage and compute, but you do not need to build real billing, just leave a clear extension point for that later.

Please make it installable with pip, target Python 3.10, include tests, and add a practical quick start and setup docs. Feel free to follow the repo docs and look up current Auth0 or S3 setup details online if needed.
