A: Hi Mehdi,

Thank you for your questions.

1) To train a model you need to have at least 20 documents reviewed and validated. Then click on the Models menu on the left sidebar and create a new model (There are multiple types, and depending on your use case, we can help you select the right model)

2) Huggingface is a repository of thousands of publically available AI models you can use, here is the list of their models: https://huggingface.co/models?pipeline_tag=token-classification&sort=trending

Please let me know if you have more questions, will be happy to help.

Best,

Walid
