@Développeur Le Studio You can pass a document with upto 2000 pages to the prebuild model or the API where you can have multiple invoices and the API should provide the result of all invoices provided they are of the supporting format and the response should be available in the documentResults section of the response with different page numbers. A quick way to test this scenario is to use the API from the studio or the REST API.

Yes, you can train the model using the Build Model API for FR v3.0 onwards.
